Y42X type membrane pressure reducing valve product introduction
The membrane type pressure reducing valve is mainly composed of adjusting spring, diaphragm, piston, valve seat, valve disc and the like. The diaphragm directly senses the downstream pressure-driven valve flap, and controls the valve opening to complete the decompression and voltage stabilization function. This product can replace the conventional partition water pipe in the urban building and high-rise building's hot and cold water supply system, saving equipment. It can also be used in the normal hot and cold water pipe network to reduce the pressure. This product has stable voltage regulation and stable voltage regulation, and is suitable for pipelines of water and non-corrosive liquid medium.
