SSS surface safety system actuators include the pneumatic piston actuator, which is used in air-operated systems and typically is mounted to the upper master and wing valve for sequenced closure during shutdown operations. To open the gate valve, the actuator supplies a downward force upon application of pneumatic pressure from an external source. When control pressure is relieved, pressure in the valve body, aided by a compression spring in the actuator, returns the piston to its normal position. The loss of control pressure causes the actuator to act as a fail-safe closed device when adapted to reverse-acting gate valves.
The pneumatic piston actuator operates valves in sizes from 1 13/16 through 16 in. The actuator piston is offered in sizes between 8 and 20 in to optimize the control pressures for the application.
