Product Description

Safe Pressure Discharging & Retaining Valve (GAJD745X)

Product Description

purpose
It is mounted on the pipeline of high buildings, fire-fighting and other water supply systems. The safe pressure discharging & retaining valve will open automatically to discharge the pressure quickly when the pressure inside the pipeline surpasses the set one so as to protect the pipeline's safety. It can also be used as the pressure-retaining valve to guarantee the water supply pressure of the main valve's upper-stream.

Product Features

features

a. Good effect of water hammer removal. Integrating the technical principles of water hammer removal
by means of slow open, quick close and slow close, so as to prevent of the water hammers at both pump start and stop. 
b.Easy operation. The valve will open or close automatically as per the operation procedures of the pump, once operates the On-Off button of the pump's motor.
c.Good effect of energy saving. The valve body is designed as full-path straight-flow type, resulting in small pressure loss, big flow, small volume and light weight.
