AX742X diaphragm type pressure relief valve installed in the pipeline, high-rise building fire water supply system and water supply system, water supply pipeline when the pressure exceeds the pressure relief valve set pressure relief valve automatically open quick pressure relief protection, pipeline safety, also can be used for holding pressure valve, the main valve upstream water supply pressure protection. Can accurately maintain the constant pressure to set the safety, once the overpressure, pressure relief valve quickly open, timely pressure relief. Close the stable and reliable, eliminating the pressure wave.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
