Hand and fluid operating relief valve

Hydraulic relief valve mainly includes two parts: Setout valve of relief valve and hydraulic drive, which is the implementation part of wellhead safety systems. It comes into the cavity of the upper drive through high-pressure oil, thus compressing lower spring to open the valve. When the wellhead suffers dangerous pressure, control mechanism discharges the pressure of the hydraulic cylinder through signals from the sensor, and the spring promotes valve stem institutions to close the valve and wellhead, so as to ensure the security of the process equipment.
