A control valve is a device used in various industrial systems to regulate the flow of fluids (liquids or gases) by varying the flow passage size. It is an essential component in process control systems, where it adjusts fluid flow to maintain the desired pressure, temperature, or liquid level within a system. Control valves can be operated manually or automatically through actuators and controllers, responding to signals from a control system to open, close, or modulate the flow to achieve the required process conditions.
