Explosion-proof valve actuator SAVEx / SARVEx series

electricmanualmulti-turn

Multi-turn actuators SAVEx .2 for open-close duty and SARVEx .2 for modulating duty are paired with intelligent ACVExC 01.2 actuator controls. The proven AUMA SAEx/SAREx range is enhanced by variable speed models. With a wide speed control ratio of 1:10, AUMA is spearheading market technology in providing variable speed actuators for use in potentially explosive atmospheres. SAVEx multi-turn actuators are rated for open-close duty and positioning duty (classes A and B) / (short-time duty S2 - 15 min). Special sizing for longer running times is available for the S2 - 30 min duty. SARVEx multi-turn actuators are rated for modulating duty (class C) S4 - 25 %. Special versions for S4 - 50 % are also available.
