Safety Pressure Relief/Maintaining Valve

It is mounted on the pipeline of high-rise fire water supply systems. When the pressure in the water supply pipeline exceeds the preset pressure of the relief valve, the relief valve will open automatically for quick pressure relief to protect the pipeline safety .It can also be used as a pressure maintaining valve to maintain the upstream pressure of water supply of the main valve.

Characteristic

1 It can keep an unchanged and safe set pressure accurately, in the event of over pressure, the relief valve will open quickly for timely pressure relief.

2 It boasts stable and reliable shut to remove the pressure after effect.
