YQ98002The filter piston type safety relief valve is installed on the pipelines of high-rise buildings, fire water supply system and other water supply systems. When the pressure in the water supply pipeline exceeds the set pressure of the pressure relief valve, the pressure relief valve will automatically open for quick pressure relief to protect the safety of the pipeline. It can also be used as a pressure holding valve to ensure the water supply pressure upstream of the main valve. Yq98002 filter piston safety relief valve produced by our company can accurately maintain the same safety setting pressure. Once overpressure is exceeded, the pressure relief valve will open quickly and relieve pressure in time. Yq98002 filter piston type safety relief valve can close stably and reliably, and eliminate pressure residual wave. The filtering piston type remote control float valve is widely used in the water supply and drainage, fire protection, industrial and mining enterprises and other industries in the water inlet pipeline of the water tower, as the water level automatic valve.
