Explosion-proof valve actuator SAVEx / SARVEx series

electricmulti-turnthree-phase

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. Design features SAVEx Torque range from 10 Nm to 1,000 Nm Output speeds from 6 to 216 rpm Limit and torque sensing Available with 3-ph AC Handwheel for manual operation Valve protection by soft start and stop Avoiding pressure surge by speed profile EMERGENCY behaviour and failure behaviour with separate speed setpoints Synchronous link – synchronous operation of two actuators Design features SARVEx Torque range from 15 Nm to 1,000 Nm Modulating torque range from 15 Nm to 350 Nm Max. number of starts 1,500 c/h Output speeds from 6 to 216 rpm Limit and torque sensing Available with 3-ph AC Handwheel for manual operation Superior positioning accuracy Valve protection by soft start and stop Avoiding pressure surge by speed profile EMERGENCY behaviour and failure behaviour with separate speed setpoints Synchronous link – synchronous operation of two actuators
