Trane ACT0672 Actuator

Maximize your control over airflow and fluid modulation with the Trane ACT0672 Actuator. This heavy-duty 24V non-spring return motor is engineered for precise 90-degree rotary actuation in commercial and industrial HVAC systems, including air handlers and rooftop units. Delivering a consistent 44 in-lb torque rating, the ACT0672 ensures reliable positioning of dampers and valves without the risk of unintended movement. As a genuine Trane OEM part, it offers a direct-fit solution that eliminates compatibility guesswork for technicians. The NSR (Non-Spring Return) logic means the unit maintains its last commanded position upon power loss, providing critical stability in complex modulation sequences. Built for continuous duty, this direct-mount actuator features a simplified screw-terminal connection and a rugged housing designed to withstand the thermal stress of mechanical rooms. Whether you are performing a damper motor replacement or a system-wide upgrade, the Trane ACT0672 provides the HVAC control components reliability required for high-performance climate control integration.

• Precise 90-Degree Actuation: Provides exact damper positioning for optimized airflow and building pressure control.
• 44 In-Lb Torque Output: Delivers sufficient force to drive medium-sized dampers and valves without stalling.
• OEM Performance: Specifically designed by Trane to maintain the original factory specifications of the equipment.
• Non-Spring Return Logic: Holds the final position across the 0-90 degree stroke, preventing mechanical shock to the linkage.
• 24V AC/DC Compatibility: Standard low-voltage operation integrates seamlessly with most existing building automation systems (BAS).

Is the Trane ACT0672 compatible with other brands?
While designed as a Trane OEM component, this 24V 44 in-lb actuator follows standard rotary specifications and can often replace actuators with similar torque and stroke profiles, such as certain Belimo or Honeywell models, provided the shaft dimensions match.

What is the benefit of a Non-Spring Return (NSR) design?
An NSR actuator like the ACT0672 is used when you need the damper to stay exactly where it is if power is lost, rather than snapping shut or open, which is ideal for precise modulation in non-safety-related paths.

Can this actuator be used for both dampers and valves?
Yes, the ACT0672 is a versatile rotary motor suitable for both air damper linkages and compatible valve assemblies requiring 44 inch-pounds of torque.
