Durable, simple and affordable: Rex Engineering valve actuators have 30 years of field proven service. They are the ideal solution for ball valves, butterfly valves and other designs.

We have also adapted our actuators into many non-valve applications. They are at work on gas compressors, industrial dish machines, pellet stoves, water filtration devices, and HVAC equipment.

Available in:

  • AC or DC powered
  • Reversible or Unidirectional
  • Female drive socket or male shaft
  • Torque range up to 1000 In. Lbs.
  • ISO mounting patterns with SAE or metric threads
  • 12 VDC, 24 VDC, 24 VAC, 115 VAC, or 240 VAC
  • UL type 4 rated for washdown protection
  • UL and CSA
  • Standard, compact & tall sizes
