API 6A Hydraulic Surface Safety Valve for Wellhead
Product Introduction
Surface safety valve (SSV) is a pneumatically or hydraulically actuated fail-safe 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,blockage,a leak in downstream equipment, or any other well emergency requiring an immediate shut down.
To ensure safety, the drilling pump is equipped with safety valve in the outlet, which is able to control the ultimate pressure of the pump within the admitted scope.
The application of safety relief valves:
1) High pressure oil / gas wells production.
2)Testing oil and gas wells with high flow rates, high wellhead pressures, or the presence of H2S.
3)Wells with hazard operational analysis showing a surface pressure barrier is needed in addition to the primary or master valve.
