Product Description

The Belimo AFRB24-SR Spring Return Control Valve Actuator is designed for precise and reliable control in commercial HVAC systems. This actuator is direct coupled and requires no crank arm or linkage, providing proportional damper control in response to a 2 to 10VDC signal or, with a 500 Ω resistor, a 4 to 20 mA control input. Its robust construction allows clockwise or counterclockwise fail-safe operation.

  • Direct coupled design eliminates the need for crank arms or linkages.
  • Accepts 2 to 10VDC or 4 to 20 mA control signals with additional resistor.
  • Fail-safe operation allows usage in critical HVAC applications.

Product Highlights

The actuator is equipped with a brushless DC motor controlled by a microprocessor, ensuring efficient operation and protection against overload at all angles of rotation. Its operational efficiency is optimized for both heating and cooling applications in air handling units.
