Explosion-proof variable speed actuators SAVEx and SARVEx

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 - 3

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
