An Electric Control Valve is an electronically powered device used to regulate the flow of liquids, semi-liquids, or gases by adjusting the passageway through which the fluid flows. This regulation is achieved by closing, partially closing, or opening the valve. Electric control valves are integral components of control systems, which typically include actuators, controllers, and sensors. These systems are designed to give operators maximum control for efficient functioning.
In a process plant, multiple electric control valves may be networked together in control loops to manage various process variables such as pressure, level, temperature, and flow. As technology has advanced, the definitions and functions of these components have evolved, sometimes overlapping, to enhance overall system performance.
