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. Hammer union is interchangable with Weco brand.

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