Understanding Honeywell Direct-Coupled Actuators
Honeywell direct-coupled actuators are electromechanical devices designed to provide precise control of various mechanical systems. They are commonly used in HVAC (Heating, Ventilation, and Air Conditioning) systems, industrial processes, and building automation. These actuators are directly connected to the device they control, such as a damper, valve, or louver, and provide the necessary torque to move it.
