AUMA AUMA Electric Actuator SA & SQ Series are high-performance electric valve actuators designed for precise control and automation of industrial valves. The SA series (multi-turn actuators) is widely used for gate and globe valves requiring linear motion, while the SQ series (part-turn actuators) is ideal for ball and butterfly valves with 90° rotation.
These electric actuators support both on-off and modulating control, delivering accurate positioning, stable torque output, and reliable performance in demanding environments. With modular design and compatibility with AC / AC01.2 control units, they can be easily integrated into modern DCS, PLC, and SCADA systems.
