Features
Pressure relief valve: It can release the pressure in the water supply pipe that exceeds the safety setting value of the pilot valve, and maintain the pressure in the pipe below a safety setting value to prevent high pressure or sudden pressure in the pipe from damaging the pipeline or equipment. It can be used for pressure relief in the fire test circulation system of high-rise buildings to prevent excessive water pressure from causing system danger.
Pressure holding valve: It can maintain the water supply pressure upstream of the main valve above a certain setting value to ensure the pressure of the water supply area upstream of the main valve.
Emergency opening valve: It is installed at the outlet of the fire sprinkler pump. When the pressure at the outlet of the pump rises to a certain setting value, this valve will open immediately.
