AX742X Pressure Relief, Pressure Sustaining Valve

Overview
AX742X Pressure Relief, Pressure Sustaining Valve, Prevent Water Hammer is mounted on the pipeline of high buildings, fire-fighting and other water supply systems.
AX742X Pressure Relief, Pressure Sustaining Valve, Prevent Water Hammer will open automatically to discharge the pressure quickly when the pressure inside the pipeline surpasses the set one so as to protect the pipelines safety. It can also be used as the pressure-retaining valve to guarantee the water supply pressure of the main valves upper-stream.
