AUMA part-turn gearboxes are used for operating part-turn valves (e.g. butterfly valves, ball valves). Type of duty: Short-time duty S2 – 15 min (open-close duty) Operation modes: – Manual operation directly with handwheel – Motor operation (by electric multi-turn actuator) Gearboxes are always provided with an input mounting flange Clockwise rotation at input shaft results…

AUMA worm gearboxes are used for the operation of part-turn valves and special valves (dampers, flue gas dampers, etc.). Type of duty: Short-time duty S2 – 15 min (Open-close duty) and inching/positioning Intermittent duty S4 – 25 % (Modulating duty only bronze) They can either be operated in: – manual operation directly via handwheel –…

GK bevel gearboxes will be used if the operating direction is to be displaced by 90°. Thus, the output torque can be increased many times.

High pressures call for multi-turn actuators providing high torques. By combining a multi-turn actuator with a GHT multi-turn gearbox, the torque range can be expanded to 120,000 Nm.

If the drive shaft is to be positioned at a certain angle to the output drive shaft, combinations of the multi-turn actuators SA with AUMA spur gearboxes GST are used. The output torque can be increased many times.

Actuators of the SQ type range for open-close duty and positioning duty 1/4 turn are rated for class A and B or types of duty S2 – 15 min. The modulating actuators of the SQR range are rated for class C or types of duty S4 – 25 %.

Actuators of the SQ type range for open-close duty and positioning duty are rated for class A and B or types of duty S2 – 15 min. The modulating actuators of the SQR range are rated for class C or types of duty S4 – 25 %. Actuators of type range SQ/SQR 07.2 – SQ/SQR…

Actuators of the SA type range for open-close duty and positioning duty are rated for class A and B or types of duty S2 – 15 min. A special version for longer running is available for the S2 – 30 min duty. The modulating actuators of the SAR range are rated for class C or…

Multi-turn gearboxes GP in combination with SA multi-turn actuators act as multi-turn actuators with higher output torques. They are typically used with stem gates and wedge gate valves. Due to their compact design, these gearboxes can also be used in confined spaces.

Actuators of the SQ type range for open-close duty and positioning duty 1/4 turn are rated for class A and B or types of duty S2 – 15 min. Explosion-proof devices must be used in plants where potentially explosive atmospheres are likely to occur. These devices are designed so that they will not act as ignition…
