Description
The Trane ACT0672 is a genuine OEM 24 V non spring return (NSR) rotary actuator designed for precise damper and valve control in HVAC systems. This robust actuator delivers reliable motion to modulate airflow and control dampers in air handler, furnace, or rooftop unit applications, making it an essential component for efficient and responsive climate control. The ACT0672 actuator is engineered to operate on 24 volt power and provides 44 inch pounds of torque with 90° rotation, allowing accurate positioning of dampers or valves as commanded by the control system. Its non spring return design (NSR) means the actuator stays in the last commanded position when energized, rather than automatically returning to a default “home” position when power is removed. This makes it ideal for applications where maintaining a set position without bias is critical.
