AUMA Riester GmbH & Co. KG

Variable speed actuators SAV and SARV

With SAV .2 multi-turn actuators for open-close duty and SARV .2 for modulating duty paired with ACV .2 actuator controls, the proven AUMA SA/SAR range is enhanced by variable speed models. AUMA is spearheading market technology offering a wide speed control ratio of 1:10. 

Actuators of the SAV type range for open-close duty and positioning duty are rated for class A and B or types of duty S2 - 15 min. A special version for longer running is available for the S2 - 30 min duty.

Actuators of the SARV type range are rated for class C or types of duty S4 - 25 %. Special versions for S4 - 50 % are also available.
