Masoneilan 8013 Series electropneumatic positioner
It senses the electrical controller signal (4–20 mA) and regulates pneumatic pressure (3–15 psi) to a valve actuator so that the valve position matches the control signal. It’s a precision feedback device used in industrial process control valves where accurate control and repeatability are required.
