Pressure relief valve: It can release the pressure in the water supply pipeline that exceeds the safety set value of the pilot valve, and maintain the pressure in the pipeline below a safety set value, so as to prevent the pipeline or equipment from being damaged by high pressure or sudden pressure in the pipeline.

It can be used for pressure relief in the fire test circulation system of high-rise buildings, as well as in cases where the water pressure is too high and poses a danger to the system.
