Spring Slightly Open Closed High Pressure Safety Valve

The spring micro-opening closed high-pressure safety valve designed by Dazhong Valve Group is a cooperative brand of YOY Yongyi Valve Group. When the pressure of the pressure vessel is abnormal, the high pressure generated will overcome the spring pressure of the safety valve, so the locking device is pushed open, forming a pressure relief channel to release the high pressure.

• The spring slightly open closed safety valve refers to the sealing of the valve valve or plunger and other seals by the elastic pressure of the spring. Once the pressure of the pressure vessel is abnormal, the high pressure generated will overcome the spring pressure of the safety valve. Therefore, the locking device is pushed open, forming a pressure relief channel to release the high pressure.

• A41Y-160/320 type spring slightly open closed high pressure safety valve single flange is suitable for equipment and pipelines of air, ammonia-hydrogen mixture, water and other media with working temperature ≤300℃.

• A41Y-160P/320P, A41Y-160R, 320R spring slightly open closed high pressure safety valve double flange is suitable for equipment and pipelines with corrosive gas or liquid medium with working temperature ≤200℃, as Overpressure protection device.

• A41Y-160/320 spring slightly open closed high pressure safety valve connecting flange according to JB/T2769-92 standard.
