Digital smart positioners are used with rotary air actuators to accurately position control valves used in throttling applications. Valworx positioners offer fast and highly accurate control of ball valves, butterfly valves and other type valves. These positioners direct mount to rotary type air actuators with the standard VDI / VDE-3845 Namur style top shaft mounting. Universal Namur mounting bracket kit is included with each positioner. Suitable for use with Valworx double acting or spring return air actuated valves, as well as most other brands utilizing the standard Namur mount.

Rugged aluminum die cast housing has superior anti-corrosion surface treatment. Multi-function digital display shows valve position, target position and other selectable parameters. Easy auto-calibration sets zero and span automatically. Automatically senses actuator open-to-close rotation (clockwise or counter-clockwise). Positioner is PRE-INSTALLED and calibrated when ordered with a Valworx air actuated valve assembly. HART protocol compatible.

The included dome indicator and Open/Close limit switches eliminate the need for a separate limit switch.
