Pressure Reducing Valve For Fire- Fighting

Jupiter controls valves manufacturer & exporter of wide range hydraulic control pressure reducing valve for fire- fighting the valve maintains a preset downstream pressure, regardless of upstream pressure or flow fluctuation. The main valve is controlled by a pilot valve, which makes the main valve modulating to maintain the downstream pressure.
The main valve comprises valve body, diaphragm, stem assembly, and seat. The valve is separated by diaphragm into two chambers, up and down. The upper chamber is control chamber, and down chamber is flowthrough chamber. The valve stem is driven by diaphragm up and down, and driven force comes from the differential pressure taken by two sides of diaphragm
