540 SERIES FLOW CONTROL VALVE

Flow control valve is composed by the main valve, flow regulating valve, needle valve, pilot valve, ball valve and piezometer, etc.

 Valve is installed at the influent pipelines of the water supply system.

 By setting the flow rate of upper pilot valve(2) and flow regulating valve(3), the flow rate go through the main valve is maintained and it will not change if any water pressure change from entry line.

 Flow control valve has two types, Piston type from DN20~DN500, diaphragm type from DN600~DN800. This valve is widely used in influent pipelines in high-rise buildings, Industries water supply system to control flow rate.
