Control Valves are characterized as those valves which are generally used in the industrial plants for controlling the operating conditions like temperature, pressure, flow with the complete or partial opening or closing in response to the received signals from the controllers which are used for comparing the set point to the process variable to those values which are being provided by the sensors which in turns is busy in monitoring the changes of such conditions. Electrical, hydraulic or pneumatic systems are used for opening and closing of the control valves. Positoners are also used which helps in controlling the opening or closing of the actuator, which are based on the electric or pneumatic signals.
