Product Description

API Spec 6A High Pressure Surface Safety Gate Valve with Pneumatic Diaphragm Actuator

High pressure oil enter into the empty cavity of upper operator, and compress the spring of lower operator to open the valve, when the wellhead equipments suffer from dangerous pressure, control system relief the pressure of cylinder after receiving the signal sent by sensor, spring push stem to close valve and wellhead equipments, ensure the equipment safety.
• When oil & gas is leaking or firing, used for security protect on well site.
• Have hydraulic safety valve and pneumatic safety valve per different driving source.
• With heat sensitive and high pressure explosion-proof equipment.
• Have two parts of actuator and preparation valve, can replace and repair standard interface.
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.
