Reliable protection for wells and flowlines
The Cameron safety shutdown valve (SSV) control system provides fail-safe shutdown of flow when pressure in the flowline falls outside a preset range. The system can also be used to perform emergency shutdown (ESD). Using a hand pump with various control components, the system maintains a zero-leakage circuit to ensure that valve movement does not inadvertently occur until a fail-safe signal is received. Controls are typically pilot tripped, but solenoids can also be used for remote control where electricity is available. The control must be manually reset after a fail-safe operation has occurred. In the event of hydraulic control line pressure loss, the valve moves to the fail-safe position.
To open: Set the arming valve to the ready position and operate the hand pump until the actuator has reached the fully open position. For a remote option, a solenoid valve must also be energized prior to hand pumping. For an automatic option, normal sensing pressure must be available to pilot valve prior to hand pumping.
To close: For local operation, manually trip the arming valve to the fail position. For a remote operation, deenergizing the solenoid valve will trip the arming valve. With an automatic option, any abnormal increase or decrease of pilot sensing pressure will trip the arming valve.
