Non-Spring Return Actuators

  • Comprehensive torque offering (18 in-lbs to 360 in-lbs), with direct coupled, linear or rotary actuators that can handle many applications.
  • All non-spring return actuators use brushless DC motor technology, which is controlled by an
    Application Specific Integrated Circuit (ASIC).
  • Minimum torque guaranteed over entire specified operating range; no loss in performance due
    to temperature, supply voltage or speed.
  • Electronically protected against overload.
  • Low power consumption provides higher efficiency and smaller transformer sizing.


Belimo actuators are designed for use in a wide variety of HVAC damper applications. With our comprehensive torque range and the ability to direct mount on standard damper shafts or jackshafts, solutions are available for control dampers, air handlers, economizer units, VAV terminal units, fan coil units, fan shutters, and unit ventilators.
