Y42X air Pressure relief valve Product introduction:
Y42X air pressure reducing valve The pressure reducing valve is direct acting Spring Diaphragm pressure reducing valve. It is mainly composed of adjusting spring, diaphragm, piston, valve seat, disc and other parts. The diaphragm directly senses the downstream pressure to drive the valve disc, and controls the opening of the valve disc to complete the function of pressure reduction and stabilization. Hot and cold of spring diaphragm pressure reducing valve in urban buildings and high-rise buildings Water supply system Medium, can replace conventional partition Water pipe , saving equipment. It can also play the role of reducing pressure and stabilizing pressure in the common cold and hot water pipe network. The spring diaphragm type pressure reducing valve can regulate and stabilize the pressure steadily. The Y42X pressure reducing valve is suitable for pipelines of water, air, oil and non corrosive liquid media.
