Working Principle of Control Valves A control valve is a mechanical device used to regulate the flow of fluids (liquids, gases, or slurries) within a system. It does so by varying the size of the flow passage, based on signals from a controller, to maintain desired process variables such as pressure, temperature, or flow rate. Below is an explanation of the working principle: --- Components of a Control Valve: 1. Body: Contains the valve components that interact with the fluid. 2. Actuator: Prov
