Ville Platte, LA
Cameron’s Valves & Measurement (V&M) group is a leading provider of valves and
measurement systems to the oil and gas industry. The group’s products are primarily used to
control, direct and measure the flow of oil and gas as it is moved from individual wellheads
through flow lines, gathering lines and transmission systems to refineries, petrochemical
plants and industrial centers for processing.
The Engineered & Process Valves division provides a wide range of valves for use in natural
gas, LNG, crude oil and refined products transmission lines. The traditional CAMERON®
fully-welded ball valve product line has been combined with the GROVE®, RING-O®, TOM
WHEATLEY®, ENTECH™ and TK® product lines. This broad offering has significantly
strengthened Cameron’s ability to serve as a single source for a wide scope of customer
requirements. The division also provides critical service valves for refinery, chemical and
petrochemical processing businesses and for associated storage terminal applications,
particularly through the ORBIT® and GENERAL VALVE®. These brands are complimented by
WKM®, TBV™ and Texsteam™ valve products and considerably expand the scope of this
division’s product offerings.
The WKM Saf-T-Seal gate valve’s smooth continuous bore minimizes turbulence. In full
bore valves pressure drop is no more than through an equal length of the same size pipe.
Seat faces are outside the flow stream and thus protected from contact with the lading
whether the valve is open or closed. The WKM Sat-T-Seal gate valve’s full round bore
makes it possible to run pigs, scrapers or hot tap cutters through the valves without
danger of damaging the valve, lodging the scraper, or jamming it with metal cutting.

WKM® SAF-T-SEAL® API 6D THROUGH CONDUIT GATE VALVES
DESIGN
The WKM Saf-T-Seal valve’s through conduit design provides these specific advantages resulting in reliable
performance and long life:
Protection of Seat Faces
•
S eat faces are outside the flow
stream and in full contact with the
gate, in both fully open and fully
closed positions. Seat life is thus
greatly extended.
Smooth, Continuous
Conduit for Flow
•
estructive turbulence is
D
eliminated. In a full bore valve,
pressure drop through the valve is
no greater than that through an
equal length of equal diameter
pipe.
Block-and-Bleed Capability
•
T he valve in closed position forms a
tight mechanical seal on both seats
simultaneously, which allows the
body cavity to be bled.

OPERATING PRINCIPLES
The WKM Saf-T-Seal gate valve is a simple, yet rugged and
reliable, through conduit gate valve. It utilizes two floating
seats to provide a complete seal with the gate. Each seat
contains a metal seat face plus a peripheral seal.
The full bore design has the same pressure drop as an
equivalent length of pipe and allows passage of all types of
scrapers (pigs).
The body center section is cast as a single piece to provide
the necessary strength to resist pipeline bending moments.
At very low pressure, the rear wave spring urges the seat
toward the gate to provide an initial seal. A plastic face seal
helps initialize the seal and provides a wiping action to help
keep the gate sealing surfaces free of debris. High
temperature valves do not have the insert. The gate is
pressed metal-to-metal against the wide flat seat face at
higher pressures. Likewise, the seat is pressed metal-tometal to the body at the higher pressure. The seat faces are
outside of the flow stream and thus protected when the
valve is in the full open or closed position. Excess body
pressure is automatically vented to the upstream conduit by
the seat. External body cavity relief systems are not required.
WKM Saf-T-Seal gate valves do not depend on lubricant for
a seal in normal operation. However, lubricants / sealants
can be injected to promote smooth operation. Seat sealant
can also be injected to affect a seal in an emergency should
the seats become damaged due to foreign matter.
The stem is sealed by the Cameron SLS Stem Seal System.
Refer to page 7 for details.
The bonnet seal is made by an O-ring. High temperature
valves use a spiral wound metal gasket with a non-asbestos
filler.
The valve stroke is established by manufacturing tolerances
and cannot get out of adjustment.
WKM Saf-T-Seal gate valves are supplied with indicator
rods for position indication as a standard for handwheel and
bevel gear operated valves.
WKM Saf-T-Seal Options are:
• Available with handwheel operators, bevel gear
operators, or less gearing (bare stem). Electric motor
operators or Piston actuators from a variety of suppliers
can be offered
• Available as surface safety valves with SAF-T-GARD

Features
Through Conduit Design: Smooth Bore, Minimum Pressure Drop, Protected Seat Faces
The WKM Saf-T-Seal gate valve’s smooth, continuous bore
minimizes turbulence. In full bore valves pressure drop is no
more than through an equal length of the same size pipe. Seat
faces are outside the flow stream and thus protected from
contact with the lading whether the valve is open or closed.
The WKM Saf-T-Seal gate valve’s full round bore makes it
possible to run pigs, scrapers or hot tap cutters through the
valves without danger of damaging the valve, lodging the
scraper, or jamming it with metal cutting.
Double-Sealing Replaceable Seats
Seats can be removed and replaced while the valve is in the
line. Seats are provided with plastic inserts and thus affect a
double seal, an initial plastic-to-metal seal in addition to a
metal-to-metal that seals both, upstream and downstream.
Gate and Stems
On-Line Overhaul
WKM Saf-T-Seal gate valves can be overhauled right on the
line. Gate, seats and other internal parts can be removed
and replaced by a trained serviceman without excessive
shutdown time.
WKM Saf-T-Seal gates and stems are Nickel
Plated. HF-6 overlay is available on request for the
gate and seat sealing surfaces.
Extensions
For valves which are to be buried,
operated from a catwalk, or
otherwise difficult to reach, stem and
body fitting extensions can be
supplied in virtually any desired length
in 6 in. increments from the minimum
extension length that can be
furnished. Extensions come as original
equipment or can be field-installed on
valves already in service.

MODELS C6, C2B AND C2C
Excellent Block-and-Bleed Capability – Automatic Relief of Excess Body Pressure
1. With equal pressure through the valve, and gate in closed position, an initial seal (1) is formed with the
raised plastic ring on the faces of the seats. The seat
inserts clean both sides of the gate each time the valve is
opened or closed.
2. As line pressure (2) is applied to the valve, it acts on
the gate, forcing it against the plastic ring on the downstream seat, compressing it until the gate rests against the steel seat. Thus, a double seal is formed –
First, a plastic-to-metal seal; then metal-to-metal. The seal
is also forced firmly into its recess. The O-ring (3) prevents
any downstream flow at this point.
3. An upstream seal is provided when body pressure is bled off.
This is caused by the force of line pressure acting against the
upstream seat (4) moving the seat against the gate and
providing a tight plastic-to-metal seal at this point. At the same
time, the O-ring (5) forms a tight seal with the seat recess.
4. Valve automatically relieves itself of excessive body pressure. When body pressure exceeds line pressure, from such causes as thermal expansion, the upstream seat
is forced back into its recess and the excess pressure in the
body is bled between the seat and the gate into the line.

WKM Saf-T-Seal gate valves do not depend on grease for a
seal in normal operation. However, in the event of damage
to sealing members, sealant can be injected to effect a seal
until the valve can be repaired.
In valves of the 6 in. (150 mm) size and larger, the sealant is
pumped through body fittings directly into a groove on the
face of the seat. In smaller valves the sealant is injected
through fittings into the valve body.
Re-Packing Under Pressure
The WKM Saf-T-Seal gate valve is equipped with Cameron
“SLS” stem packing in an enclosed packing box. Plastic stem
packing can be added while the valve is under pressure in
case of an emergency.

MODEL C6B (Cont.)
Description
The SLS Stem Seal is a system designed to provide optimum
performance with a minimum of maintenance. This seal is
hydrocarbon fugitive emissions tested and has demonstrated
seal ability not to exceed 500 ppm leakage. The SLS Stem
Sealing System has passed Fire Tests per API 6FA, BS 6755
Part 11, and ISO 10497.*
It consists of the following:
• Single Spring Loaded Lip Seal
• Lantern Ring
• Chevron Ring(s)
• Lower Pedestal
• Upper Adapter
* Editions in effect at the time of testing.
Note: Model C6B Saf-T-Seal Only.
Model C6B Details
The Single Spring Loaded Lip Seal (SLS) is a self-adjusting seal
that is designed to be maintenance free. It does not depend
on plastic packing to seal. The SLS Seal consists of a shell
and a metal spring. The shell contains four (4) separate
sealing bands to promote reliability. It is made of a filled
PTFE compound which is compatible with virtually all media/
ladings. The metal spring provides the initial seal and
provides uniform loading over a wide temperature range. It
is made from a corrosion resistant alloy making it suitable for
most all line media. The lantern ring acts as a spacer and
along with the upper adapter, acts as a bearing to center the
stem. The lower pedestal supports the SLS Seal and acts as a
stem scraper to keep contaminants away from the sealing
members. The Chevron ring(s) provide a seal should it be
necessary to inject plastic packing and helps keep foreign
matter away from the seal. The system works without a
plastic injectable. In an emergency, plastic packing can be
injected into the packing box to affect a temporary seal
while the valve is under pressure.
Metal upper adapter
centers the stem
Vee ring(s) provide
a seal should it be
necessary to inject
plastic packing and

WKM SAF-T-GARD ® PNEUMATIC DIAPHRAGM ACTUATOR
MA 12 SERIES
Description
For use with 2 in. (50 mm), 3 in. (80
mm) and 4 in. (100 mm) nominal
gate valves (Family Group Code
Y55012).
The new Cameron Saf-T-Gard diaphragm actuator product line has been developed
by using the superior features of field proven products and then combining them
with innovative technology. Particular attention has been given to safety, ease of
maintenance and cost of manufacturing.
The Cameron pneumatic diaphragm actuator series is designed to be used with all
manufacturer’s gate valves in nominal sizes of 2 in. to 6 in. (50 mm to 150 mm). Its
simple design and operating principle make this diaphragm actuator inherently
trouble free, avoiding most of the problems such as galling, misalignment, distortion
and O-ring failures commonly associated with piston type actuators.
Design Advantages
Stronger Actuator
Mounting Arrangement
Unlike other designs, the mounting bolts
on Cameron actuators are positioned
parallel to the center line of the
actuator, which loads the mounting
bolts in tension. This design is not
subject to bending and shear forces;
hence, withstanding greater separation
forces than other actuators on the
market.
Corrosion Resistant Materials
All Cameron diaphragm actuators are
manufactured to NACE MR0175, in
addition all non-stainless components
are coated with Xylan to maximize
corrosion resistance.
Superior Diaphragm Design
Cameron diaphragm material is
stronger than most designs currently on
the market, resulting in extended
service life and higher operating
pressures. Unique sealing grooves
provide additional grip and improve the
outer seal of the diaphragm housing.
The Saf-T-Gard diaphragm actuators are interchangeable with other models in the
product line, which minimizes the amount of spare parts necessary for maintenance.

WKM SAF-T-GARD ® PNEUMATIC PISTON ACTUATOR
MP 13 Series
Description
For use with 2 in., 3 in. and 4 in.
(50 mm, 80 mm and 100 mm)
nominal gate valves (Family Group
Code Y55013).
The Cameron pneumatic piston actuator product line has been developed by using
the superior features of field proven products and then combining them with
innovative technology. Particular attention has been given to safety, ease of
maintenance and cost of manufacturing. The Cameron pneumatic piston actuator
series is designed to be used will all manufacturer’s gate valves in nominal sizes of
2 in. to 4 in. (50 mm to 100 mm). Its remarkably simple design and operating
principle make this piston actuator suitable for all types of applications. The
Cameron piston actuators are interchangeable and very versatile because they
operate with many types of supply gas, compressed air, nitrogen or well gas.
Design Advantages
Stronger Actuator
Mounting Arrangement
Unlike other designs, the mounting bolts
on Cameron actuators are positioned
parallel to the center line of the
actuator, which loads the mounting
bolts in tension. This design is not
subject to bending and shear forces;
hence, withstanding greater separation
forces than other actuators on the
market.

Corrosion Resistant Materials
All Cameron piston actuators are
manufactured to NACE MR0175, in
addition all non-stainless components
are coated with Xylan to maximize
corrosion resistance.
Superior Diaphragm Design
Cameron piston actuators utilize a
single piece stainless steel snap ring to
facilitate easy cylinder removal.
The dynamic piston has a large wear
bearing that reduces any internal metalto-metal contact.

NOTE: 1.Recommended operating thrust and torque are the loads required to open or close the valve with full differential pressure
across the gate. The operator should be sized for these values.
2. Maximum allowable thrust and torque values are maximum allowable loads of the valve.
3. When “block-and-bleed” or “double block-and-bleed” service is specified, operators should be sized for these values.
4. Unless otherwise stated, handwheel rim pull for manual and motor operators shall not exceed 120 lbs.
5. All torque and thrust values are based on maximum working pressure at ambient temperature.

PARTIAL OPEN FLOW CHARACTERISTICS
The following graph approximates Flow Coefficient (CV or KV) of gate valves as a function of the valve stroke going from CLOSED
to OPEN. Note that this is an estimation only because of assumptions made in the valve stroke as well as unpredictable flow
characteristics around the gate-seat bore in the partially open position.
Gate valves are intended for on-off service. Intermittent throttling such as pressure equalization service is acceptable. Continuous
throttling is not recommended. This information is provided only to facilitate the engineering of systems in the transition
between open and closed positions of the valves. One example might be to evaluate the possibility of water hammer in liquid
pipelines.

COMMON TRIMS
T-10 Waterflood (Uninhibited)
Carbon steel body/bonnet with wetted surface, ENP plated, internal parts of corrosive resistant materials.
Temperature ratings: -20°F to +250°F (-29°C to +121°C).
T-11 Model M - 2 in., 3 in. and 4 in. (50 mm, 80 mm and 100 mm)
ASME Class 600 - 1500 Standard Trim
For non-corrosive aromatic service with concentration of MTBE to 100 percent.
T-22 Corrosive Service - Internal Parts
For substantially the same service as T-21 but where the corrosion resistance of internal parts is desirable. The valve internal
sealing members are stainless steel to gain this corrosion resistance. This trim is also usable for mildly corrosive fluids and gases
when limited corrosion of the internal body surfaces can be tolerated.
T-24 Sour Gas and Oil (NACE MR0175)
Primarily for sour gas and oil (NACE MR0175) where resistance to hydrogen sulfide embrittlement is required. Also suitable for
other chemicals, products or hydrocarbons when H2S is present. May be used when CO2 is present is smaller amounts than H2S.
T-36 Low Temperature - 50°F (-46°C) NACE
For essentially non-corrosive ladings, either liquid or gaseous. The pressure retaining components (body, bonnet and bolting) are
of impact tested materials.
T-37 Low Temperature Sour -50°F (-46°C) NACE
Primarily for sour gas and oil (NACE MR0175) where resistance to hydrogen sulfide embrittlement is required at -50°F (-46°C
service. The pressure retaining components (body, bonnet and bolting) are of impact tested materials. Also suitable for other
chemicals, products or hydrocarbons when H2S is present. May be used when CO2 is present is smaller amounts than H2S.
T-88 Anhydrous Ammonia
Special flastomers and stem nut for ammonia service. Temperature ratings: -20°F to 250°F (-29°C to 121°C).
T-94 Fire Tested to API 6FA
These valves have been qualified as fire tested and contains a special stem packing arrangement. For essentially non-corrosive
ladings. The elastomer O-rings used for seal and bonnet seals are of a material that will not tend to swell and affect the
operation of the valve. Typical examples of ladings are: gasoline, benzene, toluene, carbon-tetrachloride, 1,1, 1 trichloroethane,
Trichloroethylene perchloroethylene and phosphate ester hydraulic fluids.
T-102 High Aromatic (To 100% MTBE) 6 in. - 24 in. (150 mm - 600 mm)
ASME Class 300 - 900
For non-corrosive aromatic service with concentration of MTBE to 100 percent.
Temperature ratings: -20°F to +250°F (-29°C to +121°C). Other Trims Available on Request.
