Belimo TFB24-SR 24V Prop S/R 22In# 2-10Vdc Act

The Belimo TFB24-SR is a 24-volt normally-closed spring return proportional actuator commonly used in Heating, Ventilation, and Air Conditioning (HVAC) systems. It controls airflow by precisely positioning dampers and valves based on a 2-10 volt DC signal. Imagine a dial controlling the air circulation in your home. Instead of manually turning the knob, the TFB24-SR translates an electronic signal into physical movement, automatically adjusting airflow based on factors like temperature or system demands. Its spring return ensures the damper closes if power is lost, maintaining a safe default state. Typically found in Variable Air Volume (VAV) systems, the TFB24-SR acutator is compatible with various HVAC equipment like air handlers, fan coil units, and dampers. It ensures optimal airflow distribution, improving comfort, energy efficiency, and overall system performance.
