Piston Pneumatic Quick-Exhaust Valve Assembly

Expedite closure of surface safety valve

Schlumberger Oilfield Services

Cameron's pneumatic quick-exhaust piston-type valve enables quick exhaust of pneumatic control pressure at the actuator and decreases the amount of time for full closure of the surface safety valve (SSV).

How it works

Large 3/8-in NPT exhaust port speeds the exhaust and closure of the SSV. The supply and actuator ports are 1/2-in NPT. All materials meet NACE MR0175 specifications and include Viton.
