Mainly mounted in pipeline whose water distribution pipeline requires flow control, functioned to maintain invariable preset flow and to restrict excessive flow within a preset value. It turns the high pressure of upper stream into low, so that the flow at the lower steam of main valve will not be affected even if the pressure at upper stream changes. Pressure Grade: PN10, PN16, PN25 Diaphram Type: DN50-DN350 Piston Type: DN400-DN800
