Product: DP17 pilot operated pressure reducing valve
Pressure Rating: 1.6- 2.5Mpa Specification: DN15-50
Material: Steel WCB Standard flanges: DIN ANSI JIS JB79
This DP17 pilot operated pressure reducing valve is the new type pilot Pressure reducing valve with extra-huge membrane or diaphragm developed by our company. It is greatly improved on basis of normal pressure reducing valve. The membrane use new material, enlarging the working area, so the slight change of upper pressure or lower pressure can be fed back to membrane of main valve, and adjust the opening of main valve to ensure the constant pressure of lower stream pressure.
