Comprehensive Guide to Rotary Actuators in HVAC Systems Rotary actuators play a vital role in HVAC systems by regulating airflow and temperature through precise control of dampers and valves. These devices convert electrical signals into rotational movement, enabling accurate positioning. In HVAC systems, rotary actuators are used to adjust dampers that control the volume of air passing through ducts, ensuring optimal temperature and air quality. They also control valves regulating hot or chilled water flow in heating and cooling coils. Their reliability and efficiency make them essential for both residential and commercial HVAC systems. https://www.building-controls.com/product-type/hvac-products/actuators
