Surface Safety Valve (SSV)

General:

Surface safety valves (SSVs) are essential safety devices used in oil and gas production systems to prevent the uncontrolled release of hydrocarbons from the wellhead. They are designed to automatically shut off the flow of oil and gas in the event of an emergency, such as a blowout or equipment failure.

​

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, SSV can prevent explosion and reduce human 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 and flange. 

​

SSV is designed and maked under API 6A standard. and relief valve can reduce shut time to 3 seconds.
