Belimo NKQB24-SR Sr 24V 4Sec Run Damper Actuatr

The Belimo NKQB24-SR Sr 24V 4Sec Run Damper Actuator is an electromechanical device used in Heating, Ventilation, and Air Conditioning (HVAC) systems. It works basically like an automatic damper controller, modifying the position of a damper blade to control airflow. A synchronized motor is used by the actuator to transform a 24-volt signal from a building automation system (BAS) into rotary motion. The damper blade receives this rotary motion and is then opened or closed to regulate the airflow rate via a gear mechanism. The Belimo NKQB24-SR is a popular HVAC component that is often found in air handling units, fan coil units, and variable air volume (VAV) systems.It delivers several benefits, including improved energy efficiency, precise airflow control, and quiet running.
