Auma Electric Part Turn Gearboxes and Products

Part-turn gearboxes can be applied wherever a 90° swivel movement is required for the operation of an obturator. GS part-turn gearboxes combined with SA multi-turn actuators act as part-turn actuators. Consequently, nominal torques up to 675,000 Nm can be achieved. These combinations complement the SQ type range for part-turn valves.
