AX742X Safety Pressure Relief Holding Valve

  • Product Type : Control Valve
  • Introduction : Installed in high-rise buildings, fire water supply systems and other water supply systems on the pipeline, when the pressure in the water supply pipeline exceeds the set pressure of the pressure relief valve, the pressure relief valve automatically opens for rapid pressure relief to protect the safety of the pipeline, and can also be used as a holding valve to ensure the water supply pressure upstream of the main valve. Can accurately maintain the same security set pressure, once the overpressure, the pressure relief valve quickly open, timely pressure relief. Close smooth and reliable, eliminate the pressure after-wave.
