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 15000psi.
