Part Turn Gearboxes

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.

GS are suitable for open-close and modulating duty. Both swing angle > 90° as well as multi-turn applications are possible.

GQB gearboxes are suitable for applications requiring a simple, cost-efficient gearbox. GQB are exclusively designed for open-close duty and positioning mode. The swing angle is limited to a maximum of 90°. GHE part-turn gearboxes are used for manual operation of part-turn valves on ships.

If due to a lack of space, valves such as butterfly valves can only be operated via a lever arrangement.
