Surface safety valve (SSV) is a hydraulically actuated failsafe 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, 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. If an emergency occurs, this feature reduces the possibility of personnel injuries.
A number of SSV models are available for different well conditions (pressures, temperatures, and flow rates) and
with various connections, such as hammer union or API-6A flanges.
We provide hydraulic actuator and slab gate valve,assembled safety valve with consideration of optimal safety
and economic. The available safety valve sizes from 1-13/16" through to 7-1/16",of pressure rating from 2000psi to
