Product overview: It can release the pressure in the water pipe that exceeds the safety setting value of the pilot valve, and maintain the pressure in the pipe below a certain safety value to prevent the pipeline equipment from being damaged by high pressure or sudden pressure in the pipe. The valve has an automatic reset function. It has accurate and constant safe and stable pressure. The closing speed of the valve is adjustable. The diaphragm drive mechanism can reduce the operating hysteresis to a minimum. It can be used for pressure relief of the fire test cycle system in high-rise buildings to prevent system hazards caused by excessive water pressure.
