➀ Downstream pressure 500 psig (34.4 bar) max when valve requires
adjustment at pressure due to strength limitations of the fine-pitch threads
and high operating torque.
➁ Stainless steel L series valves are not recommended for shutoff in vacuum
or gas service, or for repetitive shutoff in liquid service.

Testing
Every Swagelok S, M, and L series metering valve is factory tested
with nitrogen at 1000 psig (69 bar). Shell testing is performed to a
requirement of no detectable leakage with a liquid leak detector.
Every Swagelok L series metering valve is tested for bubbletight seat shutoff at 100 psig (6.8 bar) differential pressure.
Every Swagelok 31 series needle valve is factory tested
with nitrogen at 1000 psig (69 bar). Seats have a maximum
allowable leak rate of 0.1 std cm3/min.
S Series M Series L Series
Wetted components listed in italics.
➀ Anaerobic-type adhesive.
➁ Straight and double-pattern M series valves.
➂ Angle and cross-pattern M series valves do not
contain a body seal.
1a Cleaning and Packaging
Swagelok metering valves with VCR end connections are
processed in accordance with Swagelok Special Cleaning and
Packaging (SC-11) (MS-06-63), page 1175, to ensure compliance
with product cleanliness requirements stated in ASTM G93 Level C.
Swagelok metering valves with other end connections are
processed in accordance with Swagelok Standard Cleaning
and Packaging (SC-10) (MS-06-62), page 1174; special
cleaning and packaging are available as an option.

Ordering Information
Select an ordering number.
S, M, and L Series
For brass S, M, and L series valves,
replace SS with B.
Example: B-SS1
M series valve shown.
S series—0.16 in. (4.1 mm) maximum panel
thickness.
M and L series—0.13 in. (3.3 mm) maximum panel
thickness.
Factory Flow Setting
The handle stop is set at 4 to 10 std
cm3/min with 15 psig (1.0 bar) inlet
pressure.
 Adjusting stop to lower flow setting
can damage valve and stem tip.
31 Series
For angle-pattern 31 series valves, add
-A to the ordering number.

Example: SS-31RS4-BL
Handle Kits
Handle kits contain handle, brass insert, and instructions.
To order a black phenolic handle, use kit ordering number
PH-5K -14K-BK.
For colored phenolic handles, replace -BK in the kit ordering
number with a handle color designator.
Example: PH-5K-14K-BL
Adjustable-Torque Handle
S Series
Vernier Handle
S, M, and L Series
■ Enhances control for setting flows.
■ Features PTFE packing and two topmounted torque adjustment screws.
■ Is available in stainless steel material

chrome-plated brass on brass
valves, as standard.
To order, add -OH to the ordering
number.
Example: SS-SS1-OH
Adjustable-Torque Handle Kits
Kits contain all parts necessary to
add an adjustable-torque handle to an
existing valve.
Slotted Handle
S and M Series
■ Helps ensure repeatable flow
adjustments.
■ Provides readings accurate to
1/25 turn.
To order, add -VH to an S series
ordering number or -MH to an M or L
series ordering number.
Examples: SS-SS1-VH
SS-2MG-MH
Vernier Handle Kits
Kits contain all parts necessary to add
a vernier handle to an existing valve.
■ Allows flow setting adjustment with a
screwdriver.
■ Is for use in installations where
handle is not easily accessible.
■ Is available in stainless steel material
on stainless steel valves and in
chrome-plated brass on brass
valves, as standard.
■ Allows valve to be panel mounted
without removing handle.

High-Temperature Stem Packing Material
31 Series
Grafoil packing extends the temperature rating to 850°F
(454°C) and requires fluorinated tungsten disulfide-based
lubricant. To order, add -G to the ordering number.
Example: SS-31RS4-G
Stem Packing Kits
PTFE and Grafoil packing kits are available. Kits include
packing, lubricant, and instructions. Select a kit ordering
number.
Stem O-Ring Materials
S, M, and L Series
Buna N O-rings are standard for brass valves; fluorocarbon
FKM O-rings are standard for stainless steel valves. When
ordering optional stem O-ring materials:
■ S series—stem and guide O-rings are replaced with the
optional material, except for the Kalrez® option; for Kalrez
material, the stem O-ring is replaced and the guide O-ring
remains the standard material.
■ S series and M series—body seal material may change, as
shown in the table below.
To order optional O-ring materials, add the desired O-ring
material designator to the ordering number.
Example: SS-SS1-BU
Special Cleaning and Packaging (SC-11)
All Series
Swagelok metering valves with VCR end connections are
processed in accordance with Swagelok Special Cleaning
and Packaging (SC-11) (MS-06-63), page 1175, to ensure
compliance with product cleanliness requirements stated in
ASTM G93 Level C.
To order special cleaning and packaging for metering valves
with other end connections, add -SC11 to the valve ordering
number.
Example: SS-SS1-SC11
