Control valve is used to regulate flow of liquid by varying the size of the flow passage as directed by signal from the controller. Control valve are used for controlling of Steam, Air, water and Gas. The closing or opening of automatic control valves is generally done by hydraulic, electrical, pneumatic actuators. With the help of modulating valve, It can be set to any position between fully closed and fully opened, valve positioners are used for ensuring the valve attains the desired degree or angle of opening. Control valves are of different structure, it could be either 2 way Globe control valve, cage control, 3 ways Globe control valve.
