​Discover our range of valves for flow control. A flow control valve regulates the flow of a fluid. Control valves normally respond to signals generated by independent devices such as flow meters or temperature gauges. With our proportional valves it is possible to handle a flow from 0,086 l/min up to 70000 l/min.
