Surface safety valve (SSV) is a hydraulically actuated fail-safe gate valve for testing oil and gas well with high flow rates, high pressures, or the pressure of H2S. The surface safety valve (SSV) is used to quickly shut down the well choke manifold upstream in the event of overpressure, failure, a leak in downstream equipment, or any other well emergency requiring an immediate shut down
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 (ESD) is recommended because it allows the actuator to be activated remotely
