The Belimo AFB24-SR Damper Control Actuator is a high-quality part that provides accurate and efficient control of HVAC systems with proportional modulation. It also helps to control the airflow and improve the system performance. This actuator uses a control signal of 2-10 VDC and delivers 180 lb-in of torque with the help of a 24 V power supply. This is due to its spring-return function that ensures safety in case of power failure. It is applied in air handling units, VAV systems, and ventilation dampers to improve the quality of air indoors and the performance of the system.
The Belimo AFB24-SR 24V 180# S/R 2/10Vdc Prop Dca is an extremely dependable actuator intended for use in HVAC systems. This actuator, which operates on a 24-volt power supply and can withstand pressures of up to 180 pounds, is designed to provide reliable performance in demanding environments. Its spring return (S/R) mechanism ensures fail-safe operation by automatically returning to a predetermined position in the event of a power outage or system malfunction. Utilizing a 2-10Vdc proportional control signal, the Belimo AFB24-SR allows for precise and responsive adjustments to airflow or fluid flow rates, resulting in optimal system performance and energy efficiency. It is commonly used in a variety of HVAC equipment, including air handling units, fan coil units, and control dampers, where it regulates the flow of air or fluids across the system.

Signs of a Faulty Belimo AFB24-SR 24V 180# S/R 2/10Vdc Prop Dca:
Inconsistent Operation: If the actuator fails to respond consistently to control signals, such as not moving to the desired position or moving erratically, it could indicate internal issues affecting its functionality.
Excessive Noise: Unusual sounds such as grinding, clicking, or buzzing during operation may suggest mechanical problems within the actuator, such as worn-out gears or bearings.
Limited Range of Motion: Restricted Range of Motion: If the actuator's range of motion is reduced or it is difficult to move to the full extent of its travel, this could indicate a mechanical obstruction, binding, or internal damage.
Failure to Hold Position: If the actuator is unable to maintain its position once set, particularly in spring return applications, it may indicate issues with the internal spring mechanism or control circuitry.
