control valve
Adjustable flow restrictor
A control valve regulates the flow of fluid through a pipe or channel by varying the size of the opening.
Unlike simple on-off valves, control valves can modulate flow continuously, responding to signals from controllers or sensors: The control valve adjusts steam pressure based on temperature readings.
Essential in industrial processes—refineries, power plants, water treatment—where precise flow management matters.
