Flange Relief Valve
The valve consists of a main valve and an external control pilot valve. It is mainly installed in the bypass of the protected water supply system of the building to ensure the pressure in the water supply area upstream of the main valve. When the pressure in the water supply pipe exceeds the set pressure of the pressure relief valve, the pressure relief valve is opened to prevent the pipeline and equipment from being damaged due to overpressure. damage. This valve is mainly used for the pressure relief of the fire test circulation system of high-rise buildings, and is an upgraded product of the spring-type safety valve. When the pressure in the water supply pipe exceeds the set pressure of the pressure relief valve, the pressure relief valve will be opened to prevent the pipeline and equipment from being damaged due to overpressure. In order to prevent the system from being dangerous due to high water pressure.
