DK-LOK® VR Series Tube Fittings
DK-LOK VR Series Tube Fitting is an inventive solution for safe installation & leak-tight tubing system, and facilitates visual inspection in installation as well as
in service.
Features
Patented \"HOOK\" Design
• Outstanding Vibration Resistant Design with patented HOOK
• Red Ring in Body facilitates Visual Inspection in Make-Up as well as in Operation
• Sturdy Stainless Steel Construction
The Patented Groove constructed both on Stainless Steel DK-LOK Tube Fitting Nut and Body locks the Nut up on the Body mechanically at 1 1/4 turns beyond the finger tight.
The Hooked (made-up) DK-LOK tube fitting provides LIFETIME Leak-Tight Sealing unless the fitting is manually un-tightened by spanDK-LOK® VR Series Tube Fittings

Prevention of Over-Tightening
The patented GROOVE constructed both on Nut and Body allows no over-tightening beyond 1 1/4 turns in the initial & re-tightening installation.
Over-tightening is not feasible in the DK-LOK VR Series Tube Fitting mechanically that is designed to provide precise 1 1/4 make-up turns keeping the four
components of front, back ferrule, nut and body fatigue-free for extended lifetime service.
The red color on body identifies DK-LOK VR Series Tube Fittings. It is disappeared by the nut when the fitting's make-up is completed with 1 1/4 turns beyond
finger tight position.
The identification helps fitters eliminate the make-up inspection with a gap gauge; it further facilitates operator's visual inspection on the running system.
illustration
As shown on above illustration, nothing is defferent from the design of Standard DK-LOK Tube Fittings except the construction area of groove on body. The gap
between body and tube thread is enhanced where the groove is on.
DK-LOK VR Series Tube Fitting is identical to the standard DK-LOK Twin Ferrule Tube Fitting in pressure-temperature rating, installation and re-installation.

For safe, reliable and leak-free DK-Lok fitting
system, tubing should be considered as one
of fitting components.
• Tubing is assembled by simple wrench
make-up on DK-Lok fitting. This results in
less assembly and maintenance costs.
• Tubing assembly on DK-Lok Fitting is
re-usable.
• Tubing is bendable. It allows lower pressure drop with fewer
connections. This in turn reduces system costs because of less
fabricating manpower
• Pipe threading or welding is diffcult to disassemble and
re-assemble.
• Piping requires skilled worker for welding & threading.
Careful handling and storage practices will protect tubing from
unnecessary scratches, nicks, or degrading the good tubing surface
finish.
•Tubing ends should be capped so any foreign materials will not
fall inside during transportation and storage.
• Do not drag across tubing rack, cement, gravel or any rough
surface.
• Do use correct tube cutter for tube material. The wrong cutter
may result in excessive deformation of the tube end.
• Do not cut deep with each turn of cutting.
• Tube cutters and hacksaws should be sharp enough.
• Hacksaw blades should have at least 32 teeth per inch.
• Do deburr tube ends before inserting in fittings.
• Tubing must be softer than fitting material. The metal tubing
must be fully annealed and suitable for bending and flaring.
• Tubing hardness must be selected according to the information
in the table 2 to 13.
• Tubing must have a surface free from scratches, draw mark, dirt,
dust and at spots.
• Tubing in oval or out-of-roundness way not fit into the fitting.
Do not force the tubing into the fitting; it may damage the fitting
sealing system on nut, ferrules, and body.
• The table 2 to 13 list tubing working pressure ratings in a wide
range of wall thickness. A too thin wall may collapse and a too
thick wall may not properly be deformed by the ferrule action.
• Do not use tubing wall thickness not listed in the table 2 to 13.
• Welded tubing should have a not measurable bead on its outside
diameter.
• The pressure rating of DK-Lok Tube Fitting is rated to the working
pressure of connective tubing.
• The allowable working pressure of tubing in various materials is
listed in the table 2 to 13.
Using like tubing and fitting material is essential for leak-free sealing
system.
Unlike material may have different mechanical properties that may
adversely affect the fitting seal on tubing.
The only exception is copper tubing with brass DK-Lok fitting.
DK-Lok Tube Fitting is designed for a wide rang of leak-free application
including gas leak proof and vacuum tight service.
Gases (helium, hydrogen, nitrogen, air, etc.) can escape even the most
minute leak-path due to their very small molecules.
Tube therefore must be handled not to have scratches, draw mark,
nicks, flat sports, dirt, and dust
Use NOT thin wall tubing for gas applications.
Heavier wall tubing resists the ferrule action whereas thin walltubing
may collapse with little resistance to ferrule action.
For Gas service, use the tubing wall listed on un-shadowed section in
table 2 to 13.
Pressure 500 psig (34.5 bar) or higher is considered generally high
pressure. In the high pressure system scratches, draw mark, nicks,
flat sports, and dirt on tubing may cause leakage.
• For gas application, select the gas applicable tubing wall
thickness from Table 2 to 13.
• Follow the suggestion on tubing selection, handling, and
installation.
DK-Lok Tube Fittings have been proved to be excellent vacuum tight
seal in many applications including analytical industry.
DK-Lok Tube Fittings comply with the leakage requirements of TA-LUFT
2002.
DK-Lok Fittings in SS316 Stainless Steel provide highly reliable
performance on cryogenic application.
Cryogenic temperature is considered to be temperatures below
-100℉ (-73℃).

• According to the requirements of ASME B31.3 Process Piping Code and ASME B31.1 Power Piping Code, allowable working pressure
calculated at -20 to 100℉ (-28 to 37℃) using S value of 20,000 psi.
• Pressure calculations are based on maximum O.D. and minimum wall thickness and no allowance is made for corrosion and erosion.
i.e., ASTM A269 1/2 in. OD x 0.035 in.WT: OD tolerance ± 0.005 in., WT tolerance ± 15%.
Calculations are based on 0.505 in.OD x 0.0298 in. WT.
• Safety Factor is 3.75 to 1, considering ultimate tensile strength of 75,000 psi.
Weld Stainless Steel Tubing Allowable Working Pressure
To determine the working pressure of weld tubing to the requirements of ASME B31.3 Code, de-rating factors below must be applied. For single weld tubing multiply by 0.80, and for double weld tubing multiply by 0.85.
Example: SS316 seamless 1/2 in. O.D. x 0.065 in. WT allowable working pressure: 4700 psi. To determine the work pressure of the single weld tubing, multiply 4700 psi by 0.80.
4700 psig x 0.80 = 3760 psig at -20 to 100℉ (-28 to 37℃).

Pressure ratings of DK-Lok tube port is governed by the connective tubing pressure rating. The allowable working pressure of those fittings with
both DK-Lok port and pipe end port are determined by the lower pressure port.
Care must be taken as fitting with elastomer O-ring sealmay have lower
temperature rating.
Kalrez®: DupPont™
Pipe thread sealant for tapered pipe thread assembly is essential to
ensure leak-free thread sealing. Sealant usually contains a lubricant.
Thread sealant fills the voids between the threads and prevents
thread galling.
Wrap PTFE tape clockwise from first thread. Do not overhang the first
thread; the tape may get into the fluid system.
Pressure Equivalents:
1 bar = 100 kPa = 14.503 psi 1 kPa = 0.01 bar = 0.145 psi

Male Connector
DMCT
Thermocouple Connector
Connects fractional tube to female ISO tapered thread
Most DK-Lok male connectors can be bored-through thermocouple fittings except
those fittings with small male thread like 1/8 in.
To order, insert T in DMC male connector part number. Example: DMCT8-8N-S
DK-Lok bored-through fittings have no shoulder or sizing angle inside the body. This
allows thermocouples or dip tubes to pass beyond the fitting male thread.
Assembly instruction
1. Position the length of thermocouple to pass through fitting male thread and hold
it to prevent shifting during assembly.
2. Wrench tightens the nut 1 1/4 turns from finger tight position, keeping the body
steady with backup wrench.
• Tighten the nut 3/4 turn for 1/8, and 3/16; 3, and 4mm Tube Fittings.

ISO 228-1
ISO Pipe Thread
The International Standards Organization prepares the ISO 228-1 and ISO 7-1 international standard to standardize the nomenclature of several
international pipe threads.
ISO 228-1 represents internal and external parallel pipe threads where pressure-tight joints are not made on the threads.
Compressing two tightening surfaces outside the threads or interposing a gasket seal will make the internal and external thread
assembly pressure-tight joint.
ISO 228-1 standardizes the following internationalpipe threads.
1. BS 2779 (BSPP) 2. DIN-ISO 228/1 3. JIS B0202 (PF)
A self-centering taper is constructed at male thread end. This taper centers a bonded gasket
to seal up on the face of the female threaded component.
DGB: NBR inner ring bonded to carbon steel outer ring.
DGV: FKM inner ring bonded to stainless steel outer ring.
A Metal Gasket performs the sealing between the reverse bevel of the fitting and the face of
the female threaded component.
A gasket is dropped into the flat bottom of the female thread. The face of the male thread
exerts a load on the gasket to seal

ISO 7-1
ISO 7-1 represents internal and external pipe tapered threads where pressure-tight joints are made by interference fit.
This thread requires sealant to fillthe voids between male and female threads that also prevents galling on threads.
The sealant usually contains lubricant.
ISO 7-1 standardizes the following international pipe threads.
1. BS 21(BSPT) 2. JIS B0203(PT) 3.DIN 2999 (male thread only)
• 55° thread angle
• Pitch measured in millimeters
• Truncation of root and crest are round
• Taper angle 1° 47’
• 60° thread angle
• Pitch measured in inches
• Truncation of root and crest are flat
• Taper angle 1° 47’

Installation Instructions
Machined Ferrule End and Tube Stub End
Port Connector is useful for close connection of two DK-Lok ports.
Be aware that Port Connector consists of machined ferrule end,
and tube stub end.
These two ends require different installation.
Machined Ferrule End
Refers to Fig. 1 & 2.
1. Remove the nut and ferrules from DK-Lok port 1.
2. Place the nut over the machined ferrule end of the port connector.
3. Finger-tighten the nut onto the port 1.
4. Wrench-tighten the nut 1/4 turn, keeping the body steady with a
backup wrench.
• Do not tighten 1 1/4 turns. This is not the standard ferrule.
• Tightens 1/8 turn for 1/16, and 1/8 in.; 3, and 4mm Tube Fittings.
Tube Stub End
Refers to Fig. 3.
1. Insert the tube stub end into the port 2 until it is bottomed on the
shoulder of the body.
2. Finger-tighten the nut on port 2.
3. Wrench-tighten the nut 1 1/4 turns, keeping the port 2 body steady
with a backup wrench.
• Tighten the nut 3/4 turn for 1/16. and 1/8 in.; and 3, and 4mm Tube
Fittings.
• For re-use, see re-assembly instruction.

DK-Lok weld ends are constructed to SCH. 80 or greater
1. Remove the nut and ferrules from the DK-Lok port.
• This protects the nut and ferrules from weld heat.
2. Cover the DK-Lok port threads with a protective device
such as DK-Lok Plug (DP).
• This protects threads and sealing surface on the DK-Lok port.
• Finger-tighten the DP to use it many times.
3. Tack weld at four positions 90 degree apart.
• This holds the fitting in alignment and concentricity.
4. Complete the welding.
5. Remove the protective device and replace the nut and ferrules.

Pre-Swaging
Units
This no-go gap gauge is useful tool to inspect the DK-Lok initially pulled-up.
Marking on tubing prior to make-up with DK-Lok.
On initial assembly, apply DK-Lok no-go gap inspection gauge to make sure
that the make-up distance is sufficiently pulled-up.
Refer to Fig 1.
1. The gap gauge does not fit the gap between the nut and the body hex.
This ensures that the fitting is sufficiently tightened on initial assembly.
Refer to Fig 2.
2. The gap gauge fits the gap between the nut and the body hex.
The fitting requires an additional tightening.
Operation Instructions
1. Insert tubing into DTM untilit is bottomed on tool.
2. Mark the tube at the top of the DTM with a pen.
3. Remove the tube from the DTM and insert into DK-Lok fitting untilit is bottomed on the shoulder of the fitting body.
4. If the marking can be seen above the fitting nut, it indicates the tube not fully bottomed inside the fitting.
Pre-swaging DK-Lok ferrules onto tubing.
Pre-swaging unit must be used to install 1 1/4, 1 1/2, and 2 in. and

Insert the tubing into the DK-Lok tube fitting until the tubing end
bottoms on the shoulder of the fitting body.
• Make sure the nut finger-tight
1. Insert tubing on the Dk-Lok tube fitting until the tubing end bottoms on the shoulder of the fitting body.
2. Wrench-tighten the nut until the tubing dose not rotate by hand or moves axially in the tting. 3. Scribe the nut at 6 o’clock position.
4. Wrench-tighten the nut to the 9 o’clock position, holding the body with a back up wrench.
• Only 3/4 turn to the 3 o’clock position is required for 1/16, 1/8, and 3/16 in.; 2, 3 and 4mm Tube Fittings.
DK-Lok Tube Fittings are gaugeable. This allows insraller to inspect that the make-up distance is sufficiently pulled-up on initial assembly.
Refer to page on 77 for Gap Gauge Operation Instructions.
DK-Lok Gap Gauge is applicable to those Dk-Lok fittings made out of SS316, Carbon steel, Brass, and Exotic alloy materials
DK-Lok can be used many times. Prior to re-assembly, ensure the components are clean and free of defects.
1. Insert the ferrules swaged tubing into the body until the front ferrule seats rmly. 2. Hand-tighten the nut.
3. Wrench-tighten the nut to the previously pulled-up position; at this point, a sharp rise in torque is felt. 4. Tighten slightly with a wrench.
In case tube bend is too close to a fitting, the bend section
shall enter the fitting.
This may not allow the tube to be bottomed in the fitting,
resulting in leaks.
Keep the proper straight length of tube as shown in the tables.
• Do not bend a tube in the fitting.
Use tube bender prior to installation onto fitting.
Do not force the tubing into the tting when it dose not
smoothly go in. It may be a deformed oval.
Scribe the nut at the 6 o’clock position and wrench-tighten the nut 1 1/4
turns to the 9 o’clock position, holding the body with a back up wrench.
• Tighten the nut 3/4 turn to the 3 o’clock position for 1/16, 1/8, and
3/16 in.; 2, 3, and 4mm Tube Fittings.
INSTALLATION INSTRUCTIONS
This instruction applies to DK-Lok Tube Fittings as well as DK-Lok Z series Tube Fittings.
DK-Lok is supplied finger-tight and ready for immediate use. Therefore fitting disassembly is not necessary for installation.
Prior to installation, make sure to have tube-end cut 90 degree, and remove burrs from inside and outside tube ends.
Use proper tube cutter and maintain a sharp cutting wheel on it.

JIS Bite Type Tube Fittings
DK Bite Type Tube Fitting is manufactured to JIS B2351 & KS B1535 under
strict ISO 9001 procedure and Type approved by DNV - Norway.
Bite type fitting consists of three parts : Body, Sleeve and Nut, and is
designed to work over medium and heavy wall tubing. See Fig-1
Allowable working temperature
Pressure reduction with temperature
Standard of DK Bite Type Fitting
Fitting Material Pressure Ranges
Pressure is rated at ambient temperature.
Note : temperature limits can greatly depend on the medium.
Note : When seal is used in the fitting, com pare allowable working
temperature between seal and fitting material and apply
the lowest temperature
When tightening nut, sleeve is driven forward on the tube then bites the
tube with the edge of sleeve, this is how sealing is achieved and results in
internal ridge inside the tube. See Fig-2
Following pressure reduction is applicable to the rating in the fitting
material pressure range for the elevated temperatures.

Preparing the tube
Tube and Bite type tube fitting are an intrinsic part of a tube system,
therefore Dk strongly advises you to take care in handling the tube in
order to have the pressure tight system.
1. Cut the tube square
2. Deburr inside and outside tube end
Tube Bending
Keeping a certain length of tubing straight from fitting shoulder to the
starting point of tube bend prevents the deformed section at a bend
entering the fitting. This will ensure safety system.
To ensure pressure-tight connection, all Dk Bite type fittings must be
disassembled prior to service to check up if small ridge inside the tube
is completely formed around front edge of sleeve. Otherwise tighten
slightly more to have it.
Sleeve may rotate on the tube that doesn't mean wrong installation. The
sleeve shall be refitted once the nut is retightened.
One of Dk Bite Type Fitting benefits is reusable many times. Further to
check up the bite condition, you need to know how to do reassembly.
Note : In case of thin wall tubing make-up, more than 1-1/2 turns may be
required.
Surface Protection
Tubing Selection
Assembly Instructions
Checking up the Bite condition
Using the same tube material as fitting is essential for the same pressure
reduction, thermal compatibility and corrosion resistance.
Note : Do not bend a tube placed in the fittings.
This may cause leakage.
1. Minimum straight length of tube from the starting point of tube bend
to the tube end may be 3 times height of the nut
Assembly Instructions
Step 1. Cut the tube at right angle with a reliable tube cutter and de-burr
inside and outside tube end with a deburring tool.
Step 2. Set a nut and sleeve on the tube. Make sure the sleeve and the nut
are facing the fitting.
Step 3. Lubricate fitting threads and sleeve. Insert tube end into fitting
body until it is firmly seated on bottom (fitting shoulder) and
hand-tighten the nut
Step 4. Tighten nut 1-1/2 turns with a wrench by holding fitting body with
a back up wrench. Marking the nut may be necessary for counting
the number of turn.
Note : In case you see no ridge formed on the tube, this would be
possibly resulted from not fully bottomed tube or not fully
tightened nut. In heavy wall tubing, though you may not see the
ridge, the pressure-tight seal is made as far as the sleeve firmly
bites the tube and is constrained axially.

Fitting can be used many times. To ensure this, parts must be clean and
free of defects.
Step 1. Insert the tube into fitting body until sleeve seats firmly in the
fitting and hand-tighten the nut.
Step 2. Tighten the nut with a wrench by holding the fitting body with a
backup wrench until a sharp rise in torque is felt. Further tighten
the nut 1/4 to 1/2 turn.
Now the reassembly is complete and ready to service.
In most cases, leakage problem occurs :
1. When the tube is not fully bottomed
2. When the nut is not tightened enough
3. When the tube is of scratches or oval
If you still face a leakage problem even if you went through above 1 to 3,
it may be the problem of extremely hard tube which is not suitable for
bending.
Note : Steel sleeve is not supposed to be loose back and forth beyond
bite point whereas Stainless sleeve could possibly move back
and forth due to its more spring-like characteristics.

is a flareless metric fitting that
consists of a body, a progressive
ring (sleeve) and a nut. On assembly,
two cutting edges of the progressive
ring bite into the outer surface of
the tube ensuring the holding for
high Tube pressure.
Available in three series, DK DIN bite
type tube fittings and accessories are
manufactured in accordance with DIN2353/DIN EN ISO8434-1
The fittings and components in this catalog are intended solely
for the assembly of connections for fluid applications.
Recommended pressure reductions (determined by the fluid
medium) for higher service temperatures.
Pressure Load Capability
Definition of pressures specified in the catalog:
a)Nominal pressure PN
The nominal pressure as referred to in DIN 2401, part 1 draft.
b)Working pressure PB
The permissible working pressure for a component is based on
the material and the operation temperature (TB) during trouble- free operation (DIN 2401, part 1 draft).
Brass*:Pressure range of brass should be adapter 30% below of the steel.
Pressure Ranges
DK DIN bite type tube fitting produces a low to high pressure, leak free connection of tubes and components in fluid
systems. The basic function of the DK DIN bite type tube
fitting is the controlled progressive bite of the ring (sleeve)
into the tube due to a unique internal geometry.
The front cutting edge (A) has already started cutting into
the tube before the second cutting edge (B) starts. As soon
as both cutting edges have cut the tube to the designed
depth further advance is limited by the stop edge (C).
Owing to the design of both cutting edges and stop edge
all forces arising are equally distributed. This distribution
along with the specially designed interior collar (D) of the
ring guarantees increased safety, particularly with regard
to vibration and flexure stresses. The design and function of
the cutting ring ensure that service vibration loading is not
present in the areas of the tubing where the bite is made.
The stop edge causes a sharp increase in tightening forces
which is clearly perceptible. After assembly, a visible collar
(E) of cut tube material must completely fill the space in front
of the first cutting edge. With stainless steel tube and
hose connections made from free cutting steel, the collar is
less due to the harder material.
During assembly, it is absolutely essential that the tube is
held firmly against the stop in the inner cone of the fitting; if
not, the cutting process will not take place satisfactorily. Reassembly can be performed an unlimited number of times.
If the tube material used deviates from the fitting material, the
tube is to be checked separately with regard to the permissible temperature range and the possible pressure reductions
required. Male stud fittings may require additional pressure
reductions, due to the mating port material, and the sealing
mechanism must also be taken into account. For male stud fittings with cutting face, additional sealants may be required.

DK DIN Bite Type Tube Fitting
This assembly instruction applicable to DIN 2353 fittings shows suitable make-up of fittings into seamless pipe in accordance
with DIN 3859.
3 Methods might be employed for assembling -
In order to ensure positive assembly, stainless steel fittings should be always pre-assembly
In and oiled pre-assembly tool. (see page 8)
◆ Assemble the fitting body directly.
• Assemble the fitting body directly.
• Using pre-swaging tool for assembly.
• Assemble standpipe & cone fitting with O-ring
1.0 Saw the tube at right angle. An angular offset of 1/2° in relation to the tube axis is
permissible.
1.1 After clean, lightly deburr tube ends at the inside and outside edge.
1.2 Don’t use a tube cutter because this would cause formation of considerable burrs and an
angular cut.
Use sawing machine or device instead.
2.0 Lubricate thread and inside of fitting body also cutting ring and thread of nut.
Don’t use grease.
2.1 Place nut and cutting ring on tube shown.
Ensure cutting ring and nut are facin g the right way.
3.0 Press tube into fitting body, up to tube abutment, then hand-tighten the nut.
4.0 Make sure the nut is in hand tight position, then the 1 1/2 turns with wrench by holding fitting body
with a second wrench. (Never turn fitting body, hold body and turn nut)
Caution!
Any deviating number of tighting turns reduces the nominal pressure and the service life of the fitting
and may cause leakages or slipping of the tube.
www.dklok.com 8
for DIN 2353
◆ Using pre-swaging tool for assembly.
5.0 Check penetration of cutting edge.
A visible ring of material should fill the space in front of the cutting ring and face.
Cutting ring may turn on tube, but should not be capable of axial displacement.
6.0 Each time the fitting is disassembled, the nut must be retightened firmly using the
same torque as required for final assembly.
7.0 Minimum length of straight tube and for tube bends, up to start of the bending radius
must be at least twice(2 X H) the nut length(H)
1.0 In order to ensure positive assembly DK-Lok Corporation DIN fittings should always be
pre-assembled in on oiled pre-assembly tool.
For direct assembly, torque-controled assembly or mechanical pre-assembly, which are
also possible.
Please refer to separate assembly instructions.
2.0 Saw the tube at right angle. An angular offset of 1/2° in relation to the tube axis is
permissible.
2.1 After clean, lightly deburr tube end at the inside and outside edge.
2.2 Don’t use a tube cutter because this would cause formation of considerable burrs and an
angular cut.
Use sawing machine or device instead.

3.0 Lubricate thread and inside of fittings body also cutting ring and thread of nut. Don’t use
grease.
3.1 Please nut and cutting ring on tube shown.
Ensure cutting ring and nut are facting the right away.
4.0 Press tube into fitting body, up to tube abutment, then hand-tighten the nut.
5.0 Make sure the nut is in hand tight position, then the 1 1/4 turns with wrench by hoIding fitting body
with a second wrench(Never turn fitting body, hold body and turn nut)
Caution!
Application of deviating numbers of tightening turns reduces the nominal pressure rating and the life
of the fitting which cause leakage or slipping of the tube.
6.0 Check penetration of cutting edge.
A visible ring of material should fill the space in front of the cutting ring and face.
Cutting ring may turn on tube but should not be capable of axial displacement.
7.0 Tighten nut until a noticeable increase in force is required.
Beyond this point, tighten the nut by 1/4 turn with wrench for final assembly.
Hold fitting body by means of a wrench.
7.1 With unfavorable mounting conditions and great tube dimensions, final assembly must
be completed in via with the fitting body.
Caution!
Any deviating number of tightening turns reduces the nominal pressure and the service life
of the fitting and may cause leakages or slipping of the fitting.

for DIN 2353
◆ Assemble standpipe & cone fitting with O-ring.
8.0 Each time the fitting is disassembled, the nut must be retightened firmly using the same
torque as required for final assembly.
9.0 Minimum lingth of straight tube and for tube bends, up to start of the bending radius
must be at least twice(2XH) the nut length(H)
1.0 Standpipes are generally supplied with pre-assembled cutting ring
Tighten the nut 1/4 turn with wrench beyond the point of a noticeable increase in force.
Hold fitting body firmly by means of wrench
1.1 With unfavorable mounting conditions and great tube dimensions, final assembly must be
completed in a vice with the fitting body to be subsequently installed.
Caution!
Any deviating number of tightening turns reduces the nominal pressure and the service life
of the fitting and may cause leakages or slipping of the fitting.
2.0 Oil O-ring
Tighten nut 1/4 of a turn beyond the point of a noticeable increase in force.
Hold fitting body firmly by means of wrench.
2.1 With unfavorable mounting conditions and great tube dimensions, final assembly must be
completed in a vice with the fitting body to be subsequently installed.
Caution!
Any deviating number of tightening turns reduces the nominal pressure and the service life
of the fitting and may cause leakages or slipping of the fitting.

Note :
This table is not intended to restrict the
use of pipe of thinner or thicker wall with
Fittings. Pipe actually used may be thinner or
thicker in nominal wall than that shown in
table 3. When thinner pipe is used, its strength
may govern the rating. When thicker pipe
is used (e.g.,for mechanical strength), the
strength of the Fittings governs the rating.

Features of DK-Lok Thread Fittings
• Wrench flat body design allowing standard Hex. wrench assembly.
• Attractive finishes to suit precision equipment.
• Much less-weight design compared to Class 3000 pipe fittings.
• Fine pipe thread construction equals or exceeds the requirement of ASME B1.20.1 to ensure maximum thread engagement.
• Male pipe threads capped for protection from damages.
• Fitting materials available in SS316, Brass and Carbon Steel.
• Pressure ratings listed are for temperature up to 37℃ (100℉)
• Pressure rating is calculated at -28 to 37℃ (-20 to 100℉) using allowable stress value of 20,000psi for SS316, 10,000psi for Brass, and 20,000psi for Carbon
Steel as per ASME B31.3 Process Piping Code.
• To determine the working pressure of ASME B31.1 Power Piping Code, multiply the ASME B31.3 rating by 0.94. Brass pressure ratings remain the same.
• The pressure ratings of reducing hex bushing (GHB), pipe plug (GP), and shaped fittings such as Elbow, Tee, Crosses are not covered in this table. See the
pressure rating in the dimensional table.

SNUBBER FITTING GS
Snubber fitting consists of fitting and sintered SS316 element.
This protects pressure gauge or instruments from system
pressure surge and shock.
The sintered element damps (snubs) the line pressure shock
but It eventually allows the gauge to readout the line pressure,
reducing the gauge’s response time.

Features
Technical information
DK-Lok weld fittings are designed to provide permanent weld connections in pressure impulse, system vibration, and temperature cycling.
Tube socket end design meets and exceeds the requirments of ASME B16.11 for ease of tube socket welding.
Use like tubing and fitting material. This ensure the same coefficient of expansion & reduction in the thermal cycle and the same corrosion resistance.
Standard fitting material is Stainless steel ASTM A276 type 316 of bar stock and ASTM A182 F316 of forging.
Pressure ratings shown in the dimensional tables are calculated in accordance with the requirements of ASME B31.3

• DK-Lok weld tube socket ports have a tapered sizing angle
at the end that holds tubing properly and provides approx.
1.5mm(0.08\") welding gap as specified in ASME B16.11.
This feature allows consistent welding assembly as well as
pre-assembly of many tubing runs before welding.
• Fittings are available in stainless steel only. Thus the part
number of table below contains the material designator-S.

High Pressure Relief Valve – Field Adjustable
When the pressure inside the system rises above the set pressure, the pressure is released to protect the system from overpressure.
• Pressure range; 1,000 ~ 10,000 psig, 10,000 ~ 20,000 psig
• Setting pressure accuracy; ±8%
• Inlet port; NPT 1/4“ or 1/4\", Outlet port; NPT 1/4\"
• Operating temperature; -20 ~ 65°C (Nylon), -20 ~ 204°C (PTFE)
• Adapters allow connection of various pressure specifications and sizes.
• Long Life due to mold springs and soft seat.
• The pressure setting is easily adjustable by the customer by directly adjusting the mood wrench bolt at the top of the valve.
Features
Application
The relief valve opens when the pressure applied to the
stem exceeds the set pressure, and closes when the
pressure falls bello the set pressure.

High Pressure Air Operated Valves
DK-NV
Air Operated Valves
It is an air pressure valve that automatically opens and closes the valve at the bottom by using air pressure.
• Normal open or normal close type are available.
• Normal open type; Normally, when the valve is open, air is supplied and the valve is closed.
• Normal close type; Normally, when the valve is close, air is supplied and the valve is open.
• Minimum air pressure for operation; 5 kgf/cm2
• The lower body through which the fluid or gas flows is of the same type as the high pressure needle valve.
• It is possible to adjust the tension of the spring by adjusting the upper bolt.
• When control of the system is required, the valve can be operated remotely via AOV.
• Because it uses air as the driving pressure, it is safer than electrical control which is dangerous for explosion.

Description of Operation
Normal-Open Type
1. In normal operation, the stem
connected to the circular plate is
lifted up and the valve remains
open.
2. At this time, when the air pressure
is applied from above, the circular
plate moves downward due to the
air pressure.
3. The stem connected to the circular
plate is also moved downwards to
block the open orifice, thus
blocking the fluid flow.
4. To reopen the valve, shut off the
incoming air pressure and exhaust
the air already in the product.
5. The restoring force of the spring
at the bottom causes the circular
plate and the stem to move up
again, and the valve opens and the
fluid flows again.
Normal-Close Type
1. In normal operation, the stem
connected to the circular plate is
lifted down and the valve remains
close.
2. At this time, if the air pressure is
applied from the lower side, the
circular plate moves upward due to
the inflating air pressure.
3. The closed orifice is opened and
fluid flows.
4. To close the valve again, shut off
the incoming air pressure and
exhaust the air already in the
product.
5. The restoring force of the spring at
the upper part causes the circular
plate and the stem to come down
again, closing the valve to block
the flow of the fluid.

What is HD Series O-Ring Face Seal Fittings?
HD Series O-Ring Face Seal Fittings is manufactured in strict accordance with the requirements of SAE J1453. HD Series O-Ring Face Seal Fittings are composed
of Body, Nut, O-ring and Sleeve, and can be completely sealed by O-ring. A 90-degree expanded tubing or brazed sleeve compresses and seals the O-ring in the
precision machined groove of the fitting body. This approach is suitable for higher pressure hydraulic systems and provides superior sealing performance. It is
also suitable for piping systems with high vibration and continuous impact pressure. HD Series O-Ring Face Seal Fittings are available in a variety of sizes for tube
diameters and wall thicknesses and are easily adaptable to tubes of inches and meters.
The outer diameter and the wall thickness of the tube is applicable please refer to Table 1.

Design and Construction
HD Series O-Ring Face Seal Fittings consist of four main parts:
Body, Sleeve, O-ring and nut.
Body
• The fitting body can be suitably applied to the piping system by
providing various shapes and flow paths.
• O-ring grooves on the body surface are machined precisely to
ensure perfect sealing.
• In addition, O-ring grooves of all fitting bodies include an O-ring
of an appropriate size basically for convenient use.
• Straight-line products are basically made of cold drawn bar
stock, Elbow, Tee and Cross are forged to improve strength and
extend life.
• O-ring grooves meet the improved dimensional requirements to
prevent O-ring deviation of Style \"B\" of SAE J1453.
Sleeve for 90° expanded tubing
• This is a method of compressing the O-ring of the fitting body by
expanding the tube end to 90°.
• With the sleeve in place, leaving the correct length for a 90°
expansion at the end of the tube, use a 90° expander to
expand the tube.
• When the tube is extended to 90°, the tube and the sleeve are
fixed to each other, and the 90° expansion surface should have
a good roughness.
• Tubes with poor surface roughness are damaged when they
come into contact with the O-ring of the body, resulting in
reduced sealing capacity and reduced service life.
Brazed sleeve
• It brazes and secures the tube and sleeve, and the sleeve
compresses the O-ring of the fitting body.
• Since the sleeve surface contacts the O-ring of the fitting body,
the sleeve itself should have good roughness.
Nut
• The screws of the body and the nut are manufactured according
to ASME / ANSI B1.1.
• Stainless steel is silver plated on the threads of the nut to
prevent galling of the screws during assembly.
• Carbon steel is basically galvanized.

Design Features Applications
V81 series ball valve offers a safe and reliable performance for a wide
range of onshore and offshore applications: water, oil, gas,
petrochemical and general duty applications.
Every valve is factory tested with nitrogen
gas @41 bar (600 psig) for leakage at the
seat to a maximum allowable leak rate of
0.1 SCCM.
The packing is tested with nitrogen for no
detectable leakage.
• Compact barstock construction for high integrity
• Blow-out proof design with internally loaded stem
• Floating Ball design providing seat wear compensation
• Micro-finished ball ensures a leak-tight shut-off on pressure
• Standard lever handle, optional butterfly and dielectric handle.

Features of V82 Series
Operation & Packing Adjustment
Application
Factory Test and Packaging
• V82 valves are designed to control fluid in full open and closed position; using V82 valves to throttle the flow may reduce the valve life.
• Valves that have not been actuated for a period of time may have a higher initial actuation torque.
• Every valve working pressure is adjusted for factory test at 1,000 psig (68.9 bar) @ 21°C (70°F). For use in higher pressure or lower
temperature range, the valve packing may be required for re-adjustment.
• Packing adjustment may be required during the valve in service.
• Analytical market requiring a valve with lowest dead volume to prevent fluid entrapment which can cause contamination.
• Control Sampling Systems, and Process Instrumentation market requiring a valve with compact size, high flow capacity and
directional indication of flow.
• Every valve is factory tested with nitrogen gas at 1,000 psig (68.9 bar) for leakage at seat to a maximum allowable leak rate of 0.1
SCCM.The packing is tested with nitrogen gas for no detectable leakage.
• Every valve is cleaned and packaged in accordance with DK cleaning standard DC-01
V82 series Ball valves are classified into 3 types according to the temperature range in use. V82 series is for general use and VL82 is
adequate to the low temperature range. VG82 can be used in the widen temperature range from low to high temperature. The exact
temperature range of each type is referred to the technical data of the type.
• Sealing is achieved without system pressure • Pressure up to 3000 psig (206 bar)
• Bi-directional flow • Lowest dead space design
• Nylon Directional handle - indicates the flow through the valve.
• Panel mounting nut - is standard and permits valve to panel or actuator.
• Top-loaded packing - allows packing adjustment with the valve in-line.
• Capsule packing - fills voids in the valve body and prevents fluid entrapment.
- allows lowest dead space.
• Support rings and discs - retains the capsule packing and prevent cold flow.
• Integral ball stem - machined from single piece bar stock.
- eliminates the backlash during handle actuation.
• One-piece body - reduces the number of potential leak points.

• Pressure and temperature compensation seat design.
• Swing-out design for fast and easy maintenance with the valve in-line.
• Chevron packing design.
• 2-way (on-off) valves with quarter-turn actuation.
Two flats on stem (10) and lever handle (13) indicate open or closed
position of the valve.
Built-in manual locking device (14) allows locking the
valve with a detent either in open or closed position.
You may also apply a pad-lock to this device. Pad-lock
hole: 8 mm (0.314 in.)
Compensation seat design requires no
pressure to create a seal.
Under high pressure, seats react on the ball
movement for sealing at upstream and
downstream.

Features
Operation and Packing Adjustment
Application
Factory Test, Cleaning and Packaging
• VH86 valves are designed to control fluid in full open and closed position, using VH86 valves to throttle the flow may reduce the
valve life.
• Stem packing can be adjustable with the handle disassembled. Tighten packing bolt clockwise to tighten the stem packing.
• Valves that have not been actuated for a period of time may have a higher initial actuation torque.
• If the valve system needs to be tested at higher pressure than the valve maximum pressure, the valve must be in open position
during the test so as not to damage the valve seat.
• Optional Sour Gas Service applicable.
VH86 series ball valve offers a safe and reliable performance in a wide range of onshore and offshore applications: Water, oil, gas,
petrochemical in heavy duty applications.
• Every valve is factory tested with nitrogen gas at 1,000 psig (68.9 bar) for leakage at seat to a maximum allowable leak rate of
0.1 SCCM. The packing is tested with nitrogen gas for no detectable leakage.
• Every valve is cleaned and packaged in accordance with DK cleaning standard DC-01.
• High flow in a compact design.
• High pressure capacity designed for blow-out proof with internally loaded ball stem.
• Micro-finished ball provides a positive seal.
• 90 degree actuation for 2-way and 180 degree actuation for 3-way ball valves.
• Panel mounting as standard.
• Chevron stem seal, adjustable with the handle disassembled.
• Handle indicates flow direction.
• Low operating torques and positive handle stops.
• Optional pneumatic actuation.

Every valve is factory tested with nitrogen gas at 68.9bar (1,000psig) for leakage to a maximum allowable leak rate of 0.1 SCCM at seat.
Hydraulic shell test is optionally performed at 1.5 times the working pressure to a requirement of no detectable leakage with a
liquid leak detector.
Every valve is cleaned and packaged in accordance with DK-Lok cleaning standard DC-01. Special cleaning and packaging in accordance
with DK-Lok standard DC-11 ensures compliance with product cleaning of ASTM G93 Level C is available on request for
valves with PCTFE and PTFE seats.
VCT86 and VCT863 Series valve provides leak-tight integrity in both low and high pressure systems in CNG and NGV applications.
Valves with PAI seat HNBR O-ring are compatible with CNG fluid.
• The Trunnion ball valve is featured by blowout-proof design
with cylindrical extensions at the top and bottom of the ball.
• The trunnion prevents the ball from shifting and permits the
ball to rotate on a vertical axis.
• Integral ball stem machined from single piece of bar stock
eliminates the backlash during handle actuation.
• Panel mounting nut is standard permitting valve to panel or
actuator
• Valves that have not been actuated for a period of time may
have a higher initial actuation torque.
• VT86 Series ball valves are designed to control fluid in full open
and full closed position.

• Fixed cracking pressure valves : V33, VP33, VH36, VCH36 Series
• Adjustable cracking pressure valves : VA33, VDA33 Series
• Lift Check valves : VL36 Series
• Cracking Pressure : Valve poppet is actuated when the pressure difference between the inlet (upstream) and the outlet (downstream)
reaches the range of cracking pressure.
• Reseal Pressure : Valves that have higher cracking pressure can be resealed to bubble-tight by the spring force.
The reseal pressure is the pressure at the same flow direction, but lower than the cracking pressure.
• Back Pressure : Valves that have cracking pressure of 5 psig (0.34 bar) and lower may not be able to return to the bubble-tight seal.
This may require back pressure to press the seal to form a bubble-tight contact in addition to the spring force.

The spring loaded poppet keeps the valve open position in the normal operation.
When an excess flow occurs downstream, the poppet immediately moves to the tripped position to stop rapid release of system fluid.
The valve returns to open position when pressure equalizes through the bleed vent constructed on poppet. The spring in the
poppet resets the valve to open position. The least volume of flow goes through the bleed vent that is less than 1% of the valve
flow rate while the valve in the tripped position.
Spring-loaded poppet design allows valve for use in vertical, horizontal or in any orientation.
• Every valve is factory tested for performance in the tripped and open position.
• Valves are cleaned and packaged as per the requirements of DK Tech’s product cleaning standard of DC-01.
• Oil free special cleaning and packaging in compliance with ASTM G93 Level C is available on request.

• Precise cracking pressure with high reliability. • Reliable Reseal performance.
• Keeping the sealing to 95~98% of Set Pressure at least. • Tamper proof design.
V61 Series Vent relief valves is designed to vent out the excess pressure from the line automatically to keep the required line pressure safely when the line pressure is exceeded
over the limitation unusually. This valves can be used in the case that the working fluid is
not harmful when vented out. The level of cracking pressure should be set by adjusting
the force of the spring in the valve before this valve is installed in the system.
This valve should be positioned perpendicularly to the direction of fluid flow in the line
and that position should be considered and the vented fluid should be not directed
to the personnel operating and the parts that has any influences on that. The line system
should be run to check the performance of the valve after the personnel operating
move to the safty zone. Because this valve is opened automatically when the excess of
the required line pressure.

To order, specify the set pressure on the valve ordering number.
Example : V66-D-4T-60BAR or V66-D-4T-870PSI
To order, select an applicable spring from the spring designator table
1 & 2. Spring kit includes spring, sticker and wire. Example : RVS-A
To order, do not specify spring designator on the ordering number.
Example : V66-D-4T
Note : The valve with no spring installed is supplied with the label
stated “NO SPRING INSTALLED” on the adjusting cap.
The valve user shall set a specific cracking pressure of the valve
supplied.
1. To increase the cracking pressure of the valve, turn the adjusting cap
clockwise to compress the spring.
2. To reduce the cracking pressure, turn counterclockwise.
3. Start the pump with the spring relaxed (eight threads showing
with the Locking Nut at bottom), with the discharging port open,
check the gauge pressure as you turn the adjusting cap clockwise to
increase the pressure to the desired operating range.
4. If the system has more than one outlet, set the valve pressure with
one outlet open, and then check again with all outlets open to make
sure that the set pressure is within the desired operating range.
5. Set the Locking Nut and the wire to maintain the set cracking pressure.
• Install the valve between the pump outlet as close as possible, and any shutoff
device in the discharge line. The preferable mounting position is vertical
with the adjusting cap at the top.
• D-Pro relief valve bypasses the system fluid to prevent instrument or sensitive
gauge in the system from excess pressure.
• When the inlet pressure overcomes the set spring pressure on the poppet,
the poppet lifts off the valve seat, allowing flow to bypass and thereby
balance the system pressure.
• If the valve has not been actuated for a period of time, it may initially crack
above the set cracking pressure.
• Cracking pressure is only sensitive to inlet pressure, and is not affected by
outlet pressure.
• Cv reduction : Valve flow may be reduced by the restriction of pipe and
tubing connected.

*Grafoil TM UCAR We reserve the right to change the specifications stated in this catalog for our coutinuing program of valve improvement.
Grafoil is a high temperature packing material that requires a load on the material to generate a seal. In air, Grafoil maximum temperature is 973°F
(523°C), in steam, Grafoil goes up to the maximum temperature of 1,200°F (648°C). Grafoil packing is not for use with pneumatic actuating valves.
Valve with standard globe and ball disc is designed for use in a fully open or fully
closed position.
Refer to Cv in the ordering information and dimensions table on Page 2.
Valve flow may be reduced by the restriction of pipe and tubing connected.
Valve ratings may be limited to the maximum working pressure of connective pipe and tubing. For valve rating with DK-Lok tube fitting end connections,
refer to DK-Lok catalog providing suggested working pressures in various tubing OD, wall thicknesses, and materials.
Extreme temperature fluctuations while valve in service may require packing adjustment. Valves that have not been actuated for a period of time
may have a higher initial actuation torque.
SS316 and C276 valve with PEEK packing is limited to maximum 600 °F (315 °C) rating; Alloy 400 valve with PEEK packing is limited to maximum 500
°F (260 °C) rating.

Operation
Information
Curve 1 - 6 indicate the minimum actuator pressure to open or close pneumatic actuators against
system pressure.
To prolong valve life, actuators should be operated at minimum air actuator pressures.
Curves shown are based on packing bolt factory adjustment.
Packing bolt adjustment may be required to maintain the valve leak-tight.
If the packing bolt is over-tightened, the actuating pressure can not overcome the friction force
between the over-tightened packing and the stem
If the packing bolt is under-tightened for low system pressures, it may leak at high system pressures.
However, packing bolt torque must be sufficiently maintained to prevent packing from leakage.
Normally
Closed Actuators
Adjusting the actuator stem drive nut affects the actuator inside the spring force.
This will also have implications for other actuator components sequentially.
All dimensions are in millimeters unless otherwise specified and only for reference subject to change. www.dklok.com

To order valves with a pneumatic double acting actuator, insert the desired
actuator designator from the chart in the valve ordering number.
Example: V16B-D6T-PK-B-BD-S

• The High Pressure Regulator valve is featured by controlling the pressure toward
downstream from zero to 1,000 psig (68.9 barg) precisely and keeping the downstream
pressure constantly after adjusting, though the upstream pressure may be fluctuated
unexpectedly.
• The diaphragm made of thin plate of stainless steel is positioned between the body and
housing to make sure of stable sealing characteristics and keep the control volume.

Safe Valve Selection
The selection of a valve for any application or system design must be considered to ensure safe performance. Valve function, valve rating, material
compatibility, proper installation, operation and maintenance retain the sole responsibility of the system designer and the user. DK-Lok accepts no
liability for any improper selection, installation, operation or maintenance.
Every valve is factory tested with nitrogen gas @1,000 psig (68.9 barg) for leakage to a maximum allowable leak rate of 0.1 SCCM at
seat. Hydraulic shell test is optionally performed at 1.5 times the working pressure to a requirement of no detectable leakage with
a liquid leak detector.
Every valve is cleaned and packaged in accordance with DK-Lok cleaning standard DC-01. Special cleaning and packaging in accordance
with DK-Lok DC-11 ensures compliance with product cleaning of ASTM G93 Level C is available on request for valves with PCTFE and
PTFE seats.

DK-Lok VBV Series Bleed Valves are designed to
vent the signal line pressure to atmosphere
before an instrument is removed and to assist in
calibration of control devices.
These are for use on instrumentation devices such
as gauge root valves and multi-valve manifolds.
Optional barbed vent tube enables containment
of fluid vented. The VBV Series are also ideal in
bleeding hydraulic systems.
Position the vent tube so that system fluid is not directed to personnel operating.
Slowly open the valve. This valve has no stem seal packing;
small amounts of fluid will go through the stem thread when they are opened.
Therefore suitable measures should be taken to protect personnel operating.
To order, add the valve body material as a suffix to the basic ordering number. S: Stainless, C: Steel. Example: VBV-M-2N-S
* Carbon Steel bodies are white galvanized for corrosion resistance.

Every valve is tested with the nitrogen @ 68 bar (1,000 psi) for leakage
at the seat to a maximum allowable leak rate of 0.1 scc/min.
The valve with PTFE ball is tested at 0.69 bar (10 psi) for leakage at the
seat to a maximum allowance leak rate of 0.1 scc/min.
DK-Lok VPV series purge valve requires a quarter turn of cap with a wrench from finger-tight for a
leak-tight seal on the first make-up.
To ensure seal to the rated pressure, snug with a wrench.
Always open the valve slowly.
These valves have no seal on cap. Therefore media may flow through the cap thread when the valves
are opened.
Operating personnel should take suitable measures to be protected from system fluids.

Manifolds and Gauge Root Valves
• D-Pro Manifolds and Gauge root valves are designed to ASME
B16.34 Class 2500 for pressure-temperature ratings.
• Pressure boundary wetted parts are selected to Chapter
III, 123 Materials of ASME B31.1.
• Valve ratings are based on ASME process piping code B31.3.
• To determine pressure rating at 37 °C (100 °F) in accordance with
Power piping code B31.1, multiply by 0.94 for stainless steel.
• Extreme or rapid temperature cycle while valve in service may
require packing adjustment. Tighten the packing bolt 1/16 turn
clockwise.
• Valves that have not been actuated for a period of time may
have a higher initial actuation torque.
• Every manifolds and gauge root valve is factory tested with
nitrogen @ 69 bar (1000 psig) for leakage at the seat to a
maximum allowable leak rate of 0.1 SCCM.
• Stem packing is tested for no detectable leakage.
• Optional hydrostatic shell test is performed with pure water
at 1.5 times the working pressure.
• For use valve in sour gas, materials for wetted components are
selected in accordance with NACE MR0175 latest revision.

Manifolds and Gauge Root Valves
• D-Pro Manifolds and Gauge root valves are designed to ASME
B16.34 Class 2500 for pressure-temperature ratings.
• Pressure boundary wetted parts are selected to Chapter
III, 123 Materials of ASME B31.1.
• Valve ratings are based on ASME process piping code B31.3.
• To determine pressure rating at 37 °C (100 °F) in accordance with
Power piping code B31.1, multiply by 0.94 for stainless steel.
• Extreme or rapid temperature cycle while valve in service may
require packing adjustment. Tighten the packing bolt 1/16 turn
clockwise.
• Valves that have not been actuated for a period of time may
have a higher initial actuation torque.
• Every manifolds and gauge root valve is factory tested with
nitrogen @ 69 bar (1000 psig) for leakage at the seat to a
maximum allowable leak rate of 0.1 SCCM.
• Stem packing is tested for no detectable leakage.
• Optional hydrostatic shell test is performed with pure water
at 1.5 times the working pressure.
• For use valve in sour gas, materials for wetted components are
selected in accordance with NACE MR0175 latest revision.

V13W Series
Rev. 01-01
Aug. 2023

Rev.01-01
Aug.2023
V13W series bellows valve offers the most difficult fluid handling appli- cation. This design with the secondary sealing system fits to the need
for a safe and reliable system.
Applications include cryogenic to high temperatures, high pressure to
vacuum in power plants, instrumentation, panels, and critical sampling
system for toxic, radioactive, and hazardous fluids.
Bellows subassembly (Figure 1)
Welding upper end of the bellows to 12. stem (weld 1) and the other
end to 19. stem weld ring (weld 2), this bellows is then welded to the
valve body (weld 3).
Bellows subassembly with the three places of welding provides all metal, hermetical sealed valve. This primary seal offers a complete sealing
between the system and atmosphere where leakage is not accepted.
Secondary seal (6), (18).
All welded stainless steel valves with secondary seal makes this valve for
the most difficult fluid containment applications.
Secondary sealing prevents leakage to atmosphere in the event of a
bellows rupture due to excessive pressurization. Leakage past the primary seal is contained by secondary seal.
Actuator threads (2)
Hardened 440C stainless steel actuator is for maximum strength, wear
resistance, and positive stem retraction.
Acme power transmission threads constructed on actuator (2) and the
bonnet (8) for low operation torque and to handle the extreme force
transmitted to the threads in high pressure bellows valve. The threads
are not in contact with the process fluid and are protected from atomospheric containments by the packing (6).
Valve actuation
Valves in high pressure tend to stick in the closed position. The ball
bearing (9), and double pin (10) on a shoulder of stem extension (11)
provide positive lifting of stem (12) and stem retraction.
Compressing or stretching the bellows allows linear motion of the stem
with the convolutions.
Ported bonnet nut (15)
This allows monitoring sealing condition of weld 3 (Figure 1) and low
seal O-ring (18).
Turns to Open
Bellows valves operated by manual actuating bar handle requires
around 1 3/4 turns on the V13WA series and 2 1/2 turns on the V13WB
& V13WC series to open the vales to full flow.
A jam nut (4) is provided for locking the gland nut (3).
Additional Features
• Non-rotating stem disc (17).
• Standard panel (14) and bottom mounting.
• Union bonnet construction allows packing (6) replacement
for maintenance.
• Safety back-seat sealing in the valve closed position.
• DK-Lok tube fitting and socket or butt weld end connections.
• Regulating stem disc for V13WA series.

Sintered Elements Technical Information
V73 Series In-line Filters
• Stainless steel 316 sintered
• High heat resistance and thermal stability up to 1,500°F(815°C)
• High permeability with low-pressure drop.
• Shape-stability with self-supporting structural elements
• Suitable for compression, vibration, and high impulse pressures.
• Precise filtration because pore size and distribution are exact and uniform.
• Chemical resistance against acids and caustic solutions in various ranges of pH.
• The sintered elements don’t permit the contaminants in the gas and liquid to pass through the elements when they are bigger
than the pore size of micron.
• Contaminants are trapped by element pores and it results in pressure buildup.
• Contamination comes earlier when ow volume is high and media is not clean.
• The filtering elements need to be replaced for minimum pressure drop as well as system purity.
Note : Clean filter valve components whenever the element is replaced.

Factory Test
Cleaning
Materials of Construction
Every pressure reducing valve is factory tested for pressure reducing.
This test is to find out whether the pressure of outlet is adjustable by 28 psig(2kg/cm2), 43 psig(3kg/cm2) and 71 psig(5kg/cm2) when
the inlet pressure comes in 1850 psig(130kg/cm2).
Every pressure reducing valve is cleaned and packaged in accordance with the requirements of our cleaning standard of DC-01.

Note:
Tubing has many benefits against piping
• Pipe threading or welding is difficult to disassemble and
re-assemble.
• Piping requires skilled worker for welding & threading.
• Piping is bulky.
• Tubing is assembled by simple wrench make-up on DK-Lok Tube
Fittings reducing assembly time and the overall cost of
installation.
• Tubing is bendable, allowing lower pressure drop with fewer
connections. This in turn reduces costs with less fabricating
manpower.
For safe, reliable and leak-free tubing system for use with DK-Lok
Fittings , tubing should be considered as one of fitting components.
The following parameters should be considered when ordering
instrumentation bright annealed seamless and welded tubing.
1. Tubing Selection
2. Tubing Handling
3. Tubing Installation
4. System Pressure
5. Welded Tubing Working Pressure
For the best performance with DK-Lok fittings, DK offers ASTM A269
and A213 bright annealed DK-Lok tubing 1/8 in. to 1 in. OD with the
following features:
• Seamless and suitable for bending and flaring.
• Free of scratches, drawing, dirt, and dust and other contamination.
• Chemically cleaned and passivated surface.
• Cold drawn and bright annealed.
• Hardness 80 HRB or less.
• Marking on tubing includes OD, wall thickness(WT), material grade,
specification, heat code, and country of origin.
• Tubing ends to be capped.
• A certain quantity to be packaged in a protective cover and
then packed in a wooden crate.
6 meter tubing cut length variations as per the requirement of ASTM
A450 standard.
ASTM A269 specifies permissible variation in tubing OD and WT, reads:
Tubing ovality variation in OD as per the requirements of ASTM A269.
For tubing OD 1/8 in. and smaller, DK supplies +/- 0.003 inch
variations for the leak-free performance with stainless steel 316
DK-Lok Fittings.
Tubing WT variations as specified in the ASTM A269 standard.
See Table 4 and 5.
Bright annealed with thermocouple clean level on the inside
surface as per ASTM A632 S3.
1. Tubing must be softer than fitting material. The metal tubing
must be fully annealed and suitable for bending and flaring.
2. Tubing hardness must be selected according to the information
in the table 4 and 5.
3. Tubing must have a surface free from scratches, draw mark, dirt,
durst and flat spots.
4. Tubing in oval or out-of-roundness may not fit into the fitting.
Do not force the tubing into the fitting; it may damage the fitting
sealing system on the nut, ferrules, and body.
Using like tubing and fitting material is essential for the thermal
compatibility and corrosion resistance. Different materials have
different hardness level that may adversely affect the fitting seal
on tubing. The only exception is copper tubing with brass DK-Lok
Fittings.
The table 4 and 5 show tubing working pressure ratings in a wide
range of wall thickness. A too thin of a wall may collapse and too
thick wall may not properly be deformed by the ferrule action.
DK-Lok Fittings are not recommended for tube wall thickness not
listed in the table 4 and 5.
Gases such as nitrogen, air, hydrogen and helium, can escape
even the most minute leak path due to their small molecules.
Heavy wall tubing resists ferrule action by coining out minor
defects of the tube surface whereas a thin wall may collapse with
little resistance to ferrule action. For gas service, use heavy wall in
white in table 4 and 5.
The weld bead should not be noticeable visually on the outside
of the tube.

Careful handling and storage practices will protect tubing from unnecessary scratches, nicks and or degrading good tubing surface finish
• Tubing ends should be capped so any foreign materials will not fall inside during transportation and storage.
• Do not drag across tubing rack, cement, gravel or any rough surface.
• Do use correct tube cutter for tube material. The wrong cutter may result in excessive deformation of the tube end.
• Do not cut deep with each turn of cutter.
• Tube cutters and hacksaws should be sharp enough.
• Hacksaw blades should have at least 32 teeth per inch.
• Deburring tube ends before inserting in the tube fittings helps prevent against system containments.
When tube bend is too close to a fitting, the bend section shall enter
the fitting. This may not allow the tube to be bottomed out in the
fitting, and may result in leakage.
Keep the proper straight length of tube as shown in table 1 below.
• Do not bend a tube in the fitting. Use tube bender.
As per ASME B31.3 Code for weld tubing working pressure, de-rating
factors below must be applied. For double butt weld tubing multiply
by 0.85 and for single butt weld tubing multiply by 0.80.
When Elastomer seal is used in the system, care must be taken for
allowable working temperature. See Table 3

DK-Lok Fitting pressure ratings are governed by the connective
tubing pressure rating. To determine allowable working pressure at
elevated temperature, multiply the working pressure at ambient
temperature shown in table 4 and 5 by the factor shown in table 2.
Example:
SS316 seamless tubing 1/2 in. O.D. x 0.065 in. WT
at 700 F. 4700 psig x 0.82 = 3854 psig.
Therefore 3854 psig is the maximum allowable working pressure
at 700 of for SS316 seamless 1/2 in. O.D. x 0.065 in. wall thickness tubing.
Example:
SS316 single butt weld tubing 1/2 in. O.D. x 0.065 in.
4700 psig x 0.80 = 3760 psig at -20 to 100°F (-28 to 37°C).
