ZPD-1111/2111 type electric pneumatic valve positionerDetailed product description：

Electric pneumatic valve positioner is an instrument used in conjunction with pneumatic control valves. It receives DC electrical signals from electric control instruments and converts them into corresponding pneumatic signals to control the stroke of the control valve. Through a feedback system, the stroke changes proportionally with the signal to ensure the correct positioning of the valve.
