400X Flow water control valve
400X Flow cast iron water control valve
200X pressure reducing valves automatically
reduce a higher inlet pressure
to a steady lower downstream pressure, regardless of chaning flow rate and varying inlet pressure.
This valve is an accurate, pilot-operated regulator capable of holding down steam pressure to a re-determined limit. When downstream pressure exceeds the pressure setting of the control pilot, the main valve and pilot valve close drip-tight.
Size: DN 50 – DN 600
Flange drilling is suitable for BS EN1092-2 PN10/16.
Epoxy fusion coating.

1. This valve adjust and maintain the maximum flow rate in outlet regadless of the change of pressure in upstream or dowenstream.
2. This kind of valve is used to adjust the flow pipe from the pump or irrigation system flow, or the flow from main pipeline to the secondary pipe system.
