Surface safety valve (SSV) is a pneumatically or hydraulically actuated fail-safe gate valve for producing or testing oil and gas wells with high flow rates, high pressures, or the presence of H2S. The SSV is used to quickly shut down the well upstream in the event of overpressure, failure,blockage,a leak in downstream equipment, or any other well emergency requiring an immediate shut down.SSV is remotely operated by an emergency shutdown device (ESD), which can be triggered automatically by high or low pressure pilot actuators.Therefore,the ground safety valve can effectively prevent the danger expansion and reduce the possibility of personnel injuries if an emergency occurs,to provide a strong guaranee for the rescue work of the oil and gas production units.A number of SSV models are available for different well conditions (pressure, temperature, and flow rate) and we accepet customization according to your actual conditions.
