Product Description

DP143-GVPR04 Pilot Steam Pressure Reducing Valve

Product Description

Brief Introduction.
 
This reducing valve is the new type pilot extra-huge membrane  reducing valve developed by our company. It is greatly improved on basis of normal 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.
