AUMA SA SAR SQ SQR Series Electric Actuator
Looking for a reliable supplier of AUMA SA SAR SQ SQR Series Electric Actuator?
We supply original AUMA electric actuators including SA, SAR, SQ, and SQR series, designed for precise valve automation in industrial applications such as oil & gas, power plants, and water treatment systems. These actuators provide high torque output, modular configuration, and advanced control integration.
Product Overview
The AUMA actuator portfolio is divided into multi-turn (SA, SAR) and part-turn (SQ, SQR) series:
- SA Series: Multi-turn actuators for open-close and positioning duty
- SAR Series: Multi-turn actuators designed for modulating duty
- SQ Series: Part-turn actuators for quarter-turn valves
- SQR Series: Part-turn actuators for modulating control applications
These actuators can be integrated with AUMA control units such as AC 01.2 for advanced diagnostics and fieldbus communication.
