Product overview

Y42X pressure reducing valve is a pressure regulating valve with piston instead of diaphragm. The service life is more than three times longer than that of diaphragm type. Diaphragm pressure reducing valves of Y110 and Y116 (threaded connection) are recommended for diameters less than DN50; Y42X (flange connection) piston type pressure reducing valve is recommended for diameter greater than or equal to DN50. This type of valve is a high adjustable pressure reducing valve. The pressure behind the valve can be adjusted as needed. After it is put into use, the pressure behind the valve is always reduced to and stable at the set value, not due to the pressure in front of the valve. The valve changes due to the fluctuation of flow. The material selection is high-quality, reliable performance and long service life.
