Maria Valve
1 / 5
Hydraulic drive safety valve, as an executive part of the safety system on the well, can classify both parts of preparation valve and driver. High-pressure oil enters the empty chamber of the driver and then presses the bottom spring so as to open the valve. If the pressure exceeds the bearing ability of the wellhead assembly, via the signal passed through the sensor, the control mechanism unloads the pressure out of the oil cylinder, and the spring pushes the valve stem to close the valve and wellhead assembly, ensuring equipment safety.
