AUMA SA multi-turn electric actuator, 10–32,000 Nm, open-close duty, IP68

The AUMA SA series is the modular base platform of multi-turn electric actuators for gate valves, globe valves and sluice gates in open-close and positioning duty. Combined with a gearbox, it also operates butterfly valves and ball valves.

Three-phase, single-phase and DC motors are available. Standard features include travel and torque sensing, handwheel, AUMA plug/socket connector and DIN/ISO valve attachment; mechanical position indicator, intermediate and tandem switches and a position transmitter are options. Functional safety up to SIL 2, up to SIL 3 with the AC 01.2 SIL actuator control.

With GK/GST gearboxes the output torque rises to 16,000 Nm, with the GHT gearbox to 120,000 Nm. Combined with the LE unit the actuator works as a linear actuator with 4–217 kN thrust.
