High Quality AUMA SA Multi-turn Actuator with GHT Gearbox High Torque Industrial Valve Drive Solution

The AUMA SA + GHT combination pairs proven multi-turn actuators with high-ratio worm gearboxes to produce the high output torques required for large industrial valves. Designed primarily for open-close duty, the system offers reliable performance under short-time duty S2 – 15 min and is engineered for long service life in harsh environments.

• Torque multiplication up to 120,000 Nm via GHT gearboxes
• Wide range of SA actuator speeds and powers matched to gearbox ratios
• Robust bronze worm wheel and cast-iron housing
• Flexible mounting flanges (F25–F40 / F48–F60)
• IP68 protection and corrosion-resistant coating (KS/KX)
• Easy integration with AUMA integral controls
• Non-self-locking design (standard) with optional configurations

Ideal for motor-operated gate and globe valves, dampers, diverters, weirs and sluice gates in water, wastewater, energy and process industries where high torque and intermittent operation are required.

• How do I select the correct SA actuator for a GHT gearbox? Use the conversion factor listed for each ratio and verify running torque for longer operating times.
• Are explosion-proof versions available? Yes – ATEX versions (II 2G Ex h IIC T3 Gb / II 2D Ex h IIIC T190 °C Db) as standard or option.
• What is the maximum continuous immersion time? Up to 96 hours at 8 m water depth (IP68 definition).
