API 6A Hydraulic Surface Safety Valve manufacturer, factory and supplier. API 6A Hydraulic Surface Safety Valve is designed to quick closure due to a pipe leak or burst, equipment malfunction, fire, or similar emergency. API 6A Hydraulic Surface Safety Valve available sizes from 1-13/16" through to 7-1/16",of pressure rating from 2000psi to 20000psi.

API 6A Hydraulic Surface Safety Valve (SSV) is normally closed,pressure needs to be applied to the actuator to compress the spring and open the valve.The pressure needed to keep the valve open can be provided with a simple hand pump which, in an emergency, is bled off on the rig floor. However, a more sophisticated system called an emergency shut down (ESD) is recommended because it allows the actuator to be activated remotely.

API 6A Hydraulic Surface Safety Valve (SSV) is located on the Christmas tree equipment or surface test manifold. The automatic trouble-proof shutoff design relies on wellhead control panel to shut off master valve and wing valve in sequence.
In case of an emergency such as fire, accidental high pressure or low pressure, SSV with control panel can automatically shut off Christmas tree unattended to protect oil & gas production safety.API 6A Hydraulic Surface Safety Valve actuator is hydraulic actuated and shut as the spring resets.
