Description
YQ98002 Filter piston type safety pressure relief valve
YQ98002 filter piston safety relief valve is installed in the pipeline of high-rise buildings, fire water supply system and other water supply system. When the pressure in the water supply pipeline exceeds the set pressure of the relief valve, the relief valve automatically opens the rapid pressure relief to protect the pipeline safety. It can also be used as pressure holding valve to ensure the upstream water supply pressure of the main valve. YQ8002 filter piston type safety pressure relief valve produced by our company can accurately maintain the same safety set pressure, once overpressure, pressure relief valve quickly open, timely pressure relief. YQ98002 filter piston safety pressure relief valve, stable and reliable closure, eliminate pressure aftershock.
