What is a valve positioner? What are its principles and functions?

Valve positioners, classified by structure into pneumatic valve positioners, electro-pneumatic valve positioners, and intelligent valve positioners, are major accessories for control valves. They are usually used with pneumatic control valves. They receive output signals from the regulator and then use their output signals to control the pneumatic control valve. After the control valve operates, the displacement of the valve stem is fed back to the valve positioner through a mechanical device, and the valve position is transmitted to the upper-level system via an electrical signal.
