AUMA SA Multi-turn Actuator with GHT Gearbox High Torque Valve Drive Industrial Open-Close Duty Solution

Product Overview

AUMA SA multi-turn actuators combined with GHT multi-turn gearboxes deliver high-torque solutions for the reliable operation of industrial valves and special valves. The SA series (07.2–16.2) provides precise open-close duty performance with 3-phase AC motors, while the GHT series (320.3–1200.3) multiplies torque through robust worm gearboxes. Together they enable torque outputs from several thousand to over 100,000 Nm, suitable for demanding process applications.

Key Features

• Modular SA + GHT combination for flexible torque and speed selection
• Short-time duty S2 – 15 min (open-close) as standard
• High reduction ratios (approx. 10:1 to 20.5:1) with conversion factors for accurate actuator sizing
• Self-locking or non-self-locking options depending on ratio
• IP68 enclosure protection and wide ambient temperature range
• Compatible with AUMA NORM, AM or AC integral controls
• Corrosion protection KS (standard) or KX (option)
• Bronze worm wheel and cast-iron housing for durability

Technical Specifications

Applications

Gate valves, globe valves, louvre dampers, stack dampers, diverters, weirs and sluice gates in power plants, water treatment, oil & gas, chemical and general industrial processes requiring high torque and reliable open-close operation.

Frequently Asked Questions

• What is the conversion factor used for? It converts output torque to required input torque for correct SA actuator sizing (±10 % after running-in).
• Can the combination be used for modulating duty? Yes, on request (S4 – 25 %, class C).
• Is thermal motor protection included? Yes – thermoswitches or PTC thermistors; already integrated in AM/AC controls.
• What switchgear power classes are available? A1–A3 (and higher with additional control box).
