Pilot Operated Pressure Reducing Valve DP143
Structural characteristic & 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.
