A control valve is a device that regulates the flow of fluids or gases through a pipeline by varying the opening and closing of an internal passage. Control valves are used in a wide range of industries to maintain process parameters such as pressure, temperature, flow rate, and level. The benefits of using control valves include improved accuracy, reliability, and safety, as well as reduced downtime and maintenance costs.
