Role and Use

When the pressure in the water supply pipe exceeds the rated pressure of the pressure relief valve, the pressure relief valve opens to prevent the pipeline and equipment from being damaged due to overpressure, and it can be used for the pressure relief of the fire test circulating system in high-rise buildings to prevent the danger of the system caused by the high water pressure.
