DP17 pilot operated pressure reducing valve Pressure Rating: 1.6- 2.5Mpa Specification: DN15-50 Material: Steel WCB Standard flanges: DIN, ANSI, JIS
DP17 Pressure Reducing Valve Structural characteristic and purpose
This reducing valve is the new type pilot extra-huge membrane pressure reducing valve 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.
This series of pressure reducing valve is the company reference foreign advanced products and research and development of new type enormous success guide diaphragm pressure reducing valve, the product of the pressure reducing valve in ordinary based on improved greatly. Diaphragm used the new material, and the work area greatly processing, so the valve upstream pressure or downstream load subtle change can be accurately and timely feedback to the main valve diaphragm, to adjust the main valve opening, ensure the stability of the downstream pressure.
This Pilot Operated Pressure Reducing Valve product another prominent features: the same body can be installed and exchange the voltage valve in the more than at the same time, realize temperature control, upstream pressure control, remote switch control, etc.
