Electric pneumatic positioners
The linear function is the best choice for valve control with high accuracy. Due to the compressibility of air, pneumatic actuators require positioner that eliminates the unpredictable variable. It checks the difference between the input signal and the opening of the valve and reduces the difference between the same.
Area of application:
With pneumatic linear actuators
0,2-1 bar or 0/4-20 mA
