Pneumatic positioners are used with rotary air actuators to accurately position control valves used in throttling applications. Our position-ers offer fast and accurate control of ball valves, butterfly valves and other type valves. Suitable for use with double acting or spring return air actuated valves, as well as most other brands utilizing the standard Namur mount.



Pneumatic positioners convert either a 4-20mA or 3-15 PSI input control signal to a proportional pneumatic output. This output is fed to an air actuator which in turn controls the valve position and flow (combined with mechanical position feedback). Fast and accurate response times from input change to valve movement. Easily adjustable zero and span if required. Positioner can be setup to rotate output shaft clockwise or counter-clockwise 90 degrees. Easily convertible from spring return to double acting or vice versa.
