Introduction of Y42X type direct acting spring diaphragm pressure reducing valve

Y42X型直接作用弹簧薄膜式减压阀 属于直接作用式薄膜弹簧减压阀。 This series of Y42X direct acting spring diaphragm pressure reducing valve is a direct acting diaphragm spring pressure reducing valve. It is mainly composed of adjusting spring, diaphragm, piston, valve seat, valve disc and other parts. The diaphragm directly senses the downstream pressure to drive the valve flap, and controls the valve flap opening degree to complete the function of pressure reduction and pressure stabilization.
Y416X型直接作用弹簧薄膜式减压阀 在城市建筑、高层建筑的冷热供水系统中,可取代常规分区水管,节省设备。 The Y416X direct acting spring diaphragm pressure reducing valve can replace the conventional partitioned water pipes in the hot and cold water supply systems of urban buildings and high-rise buildings, saving equipment. It can also play the role of decompression and voltage stabilization in the common hot and cold water pipe network.
This product has stable pressure regulation and voltage stabilization action, and is suitable for water and non-corrosive liquid medium pipelines.
