A valve positioner is a device that adjusts the valve
actuator's position based on a control signal.
Valve positioners compare a control signal to a valve
actuator's position and move the actuator accordingly.
They are used with both linear valves and rotary
valves. Valve positioners are used when the 0.2 to 1
bar pressure in the diaphragm chamber is not able to
cope with friction and high differential pressures.
