Surface safety valve (SSV) is a hydraulically or pneumatically actuated fail-safe gate valve for testing service in 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
The valve is used in conjunction with an emergency shut down system(ESD) and normally installed upstream of the choke manifold. The valve is remotely operated either manually by push button or automatically triggered by high/low pressure pilots.
