Product Overview
The AUMA actuator series includes multiple configurations to meet different valve automation requirements:
- SA Series – Multi-turn actuators for open/close and positioning duty
- SAR Series – Multi-turn actuators designed for modulating control
- SQ Series – Part-turn actuators for 90° rotation valves
- SQR Series – Part-turn actuators for modulating applications
- SAEx Series – Explosion-proof multi-turn actuators
- SQEx Series – Explosion-proof part-turn actuators
These actuators can be integrated with AUMA control units such as AC 01.2, supporting advanced diagnostics and industrial communication protocols.
