Limitorque Non-Intrusive Multi-turn Actuators
Non-Intrusive Multi-turn Actuators

The Limitorque® MX Series B (MXb) non-intrusive, multi-turn, smart electric actuator offers superior reliability, enhanced analytics and an improved user experience. It is designed for application versatility and tackles the toughest, most critical services within the oil and gas upstream and midstream, commercial power, chemical, fresh and wastewater, and general industries.

Features and Benefits

  • Broad versatility owing to a wide variety of configurations, including torque-only, thrust-based, linear thrust base and rising stem applications
  • Uncompromised reliability and superior service life from the use of higher-rated components and isolation of input/outputs from outside interference
  • Enhanced user experience from an improved user interface, simplified menu structure, and multiple configuration options that allow for faster installation and commissioning
  • Higher process control visibility through advanced diagnostics and analytics, a larger storage capacity, and high-resolution visualization of operational graphs, logs and trend data
  • Weatherproof, explosion-proof and submersible applications
  • 100% repeatable and redundant absolute encoder for position sensing; configurable electronic torque switch for torque sensing
  • Three-phase 50/60 Hz options from 208 to 575V
  • Configurable at the actuator via 11 languages: English, Spanish, German, French, Italian, Portuguese, Mandarin, Russian, Bahasa Indonesia, Katakana and Turkish
  • Standard UPS for 12 to 24 VDC-powered commissioning without mains or backup power to feedback and alarms during loss of mains
  • Four standard 5A relays for status and alarms; one 5A monitor relay for remote operation feedback
  • The MXb actuator's display and control electronics assembly are backward compatible and can be easily retrofitted to previous MX actuator models.
