Control Valve Working Animation A. Control Valve Actuators Principle Control valves are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a “setpoint” to a “process variable” whose value is provided by sensors that monitor changes in such conditions. Control Valve is also termed as the Final Control Element. B. Control Valve Working Animation The opening or

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
