Get A QuoteTwo port control valves are used to control water flow to a process, for example, for steam boiler level control, or to maintain the water level in a feedtank. They may also be used on heat exchange processes, however, when the two-port valve is closed, the flow of water in the section of pipe preceding the control valve is stopped, creating a dead-leg.
