  • Description:Y42X Water pressure reducing valve manufacturer, factory and supplier.
Y42X Water pressure reducing valve manufacturer, factory and supplier. Y42X Water pressure reducing valve is direct acting diaphragm spring structure, Y42X Water pressure reducing valve mainly consists of adjusting spring, diaphragm, piston, seat, disc and other parts.The pressure downstream of the diaphragm can be directly sensed to drive the disc, and the water pressure reducing valve opening can be controlled to realize pressure reduction and pressure stabilization. Y42X Water pressure reducing valve can replace the conventional sectional water pipe and save equipment in the cold and hot water supply system of urban buildings and high-rise buildings.Y42X Water pressure reducing valve can also be in the usual hot and cold pipeline. 

Y42X Water pressure reducing valve is a pressure regulating valve with a piston instead of a diaphragm. More than three times longer life than the diaphragm type. For diameter less than DN50, it is recommended to use Y110X(threaded connection) diaphragm pressure reducing valve; Diameter greater than DN50 choose Y42X(flange connection) piston type pressure reducing valve. Y42X Water pressure reducing valve is an adjustable pressure reducing valve, the pressure after the valve can be adjusted according to the need, put into use after the valve pressure is always reduced to and stable at the set value, not due to the fluctuation of the pressure before the valve, the valve material selection quality, reliable performance, long service life.

When Y42X Water pressure reducing valve is resistant to high pressure and the outlet pressure is high, the film pressure reducing valve is not good, and the piston type can adapt to the high outlet pressure. Applicable to the working temperature of 0-90℃ water, non-corrosive liquid pipeline, in the high-rise building hot and cold water supply and coal mine water supply system, Y42X Water pressure reducing valve can simplify the system equipment, reduce engineering costs, can also play a pressure reduction in all kinds of cooling systems, is one of the user's ideal pressure reducing valve products.
