API Gate Valves

Cameron offers a full range of gate valves for surface and subseaapplications. Selection of a valve for a specific application depends on a number of factors including bore size and working pressure.

Standard and customized configurations of solid block valves areavailable for use in Christmas tree applications, along with single gatevalves. Solid block valves provide a more compact design and improvedfire-resistance with fewer potential leak paths. However, single gate valveChristmas trees provide flexibility in configuration and easy replacement.

The reliability of Cameron gate valves makes them essential com-ponents for both subsea and surface applications. Large bore and highpressure valves are available for use in varying service conditions includinghigh temperature applications, formation fracturing operations, drillingand subsea production manifolds.

All Cameron gate valves are available with a full range of CameronWillis actuators, chokes and controls providing a single source of supply.

API Gate Valves

FL and FLS Gate Valve

FLS-R Gate Valve

Cameron offers both slab-style and expanding-style gate valves in fullbore through conduit designs to meet API 6A requirements.

FL™, FLS™ and FLS-R™ Gate ValvesSlab-style gates are used in the Cameron FL, FLS and FLS-Rforged body gate valves for both manual and actuatedapplications. These valves meet or exceed the requirementsof API Specifications 6A, 6A SSV/USV and 17D. The slab-style gate effects a metal-to-metal seal on the flow stream.In addition, slab-style gates may also be used when wirelinecutting is required.

Common features of the FL, FLS and FLS-R Gate Valvesinclude inert, spring-loaded, pressure-energized lip seals which areinstalled between each seat and body. These seals assist in low-pressuresealing and protect against intrusion of particle contaminants into thebody and seal areas.

The FLS-R valve is used in manually operated, large bore applications.The manual FLS-R valve shares many of the the same features as the FLSvalve and it incorporates a lower balance stem and a unique ball screwmechanism which provide remarkably low operating torque. The FLSvalve is used in high pressure, large bore applications requiring actuation.• FL Gate Valves – sizes 2-1/6" to 4-1/16"; 2000 to 5000 psi WP• FLS Gate Valves – sizes 1-13/16" to 9"; 2000 to 20,000 psi WP• FLS-R Gate Valves – sizes 4-1/16" to 11"; 5000 to 15,000 psi WP

M™ and M 215™ Gate ValvesExpanding-style gates are used in the Cameron M andM215 cast body manual gate valves. The Pow-R-Seal® gatedesign provides a positive seal against the upstream anddownstream seats simultaneously as the handwheel istightened. This seal is unaffected by line pressure fluctua-tions and vibration.

The M215 gate valves share many of the same featuresas the M and have a lower balance stem to reduceoperating torque.

• M Gate Valves – sizes 2-1/16" to 4 1/16"; 2000 to 5000 psi WP• M 215 Gate Valves – sizes 1-13/16" to 3 1/16"; 10,000 psi WP

Saf-T-Gard® Actuators

Cameron designs and manufactures a full range of Saf-T-Gard pneumaticpiston and diaphragm actuators and hydraulic and wireline cuttingactuators. These actuators can be used on the full line of Cameron gatevalves in wellhead and pipeline applications. Cameron actuators aredesigned to be interchangeable and offer a wide range of flexibility.

Actuator Bonnet AssembliesActuator bonnet assemblies on Cameron FL, FLS and M gate valves pro-vide the interface between the gate valve and actuator. These bonnetassemblies are compatible with Cameron hydraulic and pneumaticactuators. They can also be used on other manufacturers’ direct-actingand reverse-acting gate valves.

The bonnet assembly isolates all of the well bore fluids in the valvebody from the actuator. Field-proven performance, combined withinnovative technology, allows Cameron actuator bonnets to matchspecific gate valves metallurgical and elastomeric requirements to extend wear life.

Pneumatic Saf-T-Gard ActuatorsCameron pneumatic Saf-T-Gard actuators are available in piston anddiaphragm designs.

The MP pneumatic piston actuators are interchangeable and operatewith many types of supply: gas, compressed air, nitrogen, or well gas.These actuators are designed to meet a wide range of service require-ments and are available in single and dual piston versions in a variety ofsizes and pressure ranges.

The MA pneumatic diaphragm actuators’ simple design and operatingprinciple make it inherently trouble-free. This series is available in avariety of actuator diameters and configurations to meet a variety ofservice requirements.

Hydraulic Saf-T-Gard ActuatorsCameron hydraulic Saf-T-Gard MH series of actuators offers an intrinsicallysafe design that can be used in hazardous areas. All Cameron hydraulicactuators are interchangeable with standard bonnet adapters. The MHseries is available in single and dual piston models and in rising and non-rising stem configurations. These actuators offer an innovative, feature-rich design that offers the power required to operate safely and reliably.

Wireline Cutting ActuatorsCameron offers two models of hydraulic wireline cutting actuators: the MSVW and the MHW.

The MSVW is an actuator for a surface safety valve. It is modular and features interchangeable spring and wireline cutting modules for easy conversion from wirecutting to non-wirecutting applications.

The MHW is a wireline cutting version of the MH series pistonhydraulic actuator. It is a single piston design which minimizes theamount of fluid required to compress the large power spring.
