Hydraulic Surface Safety Valve - SSV is designed to quick closure due to a pipe leak or burst, equipment malfunction, fire, or similar emergency.The Surface safety valve (ssv) is normally closed,pressure needs to be applied to the actuator to compress the spring and open the valve.
The pressure needed to keep the valve open can be provided with a simple hand pump which, in an emergency, is bled off on the rig floor. However, a more sophisticated system called an emergency shut down system(ESD) is recommended because it allows the actuator to be activated remotely.
CCSC designs and manufactures hydraulic actuator and slab gate valve,assembled safety valve with consideration of optimal safety and economic. The available safety valve sizes from 1-13/16" through to 7-1/16",of pressure rating from 2000psi to 15000psi.
