York S1-025-31978-000 Damper Actuator

The York S1-025-31978-000 Damper Actuator is a professional-grade 24V HVAC actuator specifically engineered for high-cycle performance in bypass and zone-controlled systems. This OEM York replacement part provides the precise torque required to modulate damper blades, ensuring balanced static pressure and efficient airflow management across multiple duct zones. Built for seamless integration with zoning system controllers, the S1-025-31978-000 eliminates the need for field-added components, reducing labor time during installs or service calls.

As a veteran tech, you know that consistent damper positioning is critical for maintaining HVAC system efficiency. This actuator operates on a standard 24VAC signal, offering reliable feedback and movement to prevent temperature stratification in commercial or residential layouts. Whether you are replacing a failed unit in a bypass damper assembly or upgrading a zone control system, the robust internal gearing and electrical components of this genuine York part are designed to withstand the continuous duty cycles found in demanding HVAC environments.

• Precise Airflow Control: Facilitates accurate modulation of bypass and zone dampers to optimize climate distribution.
• OEM Compatibility: Authentic York S1-025-31978-000 ensures exact fitment and electrical alignment with existing control boards.
• Durable 24V Operation: Engineered for long-term reliability within standard low-voltage HVAC/R control circuits.
• Simplified Installation: Direct-mount design speeds up the replacement process for field technicians.

Is the S1-025-31978-000 compatible with third-party zoning systems?
While designed for York and Johnson Controls equipment, this 24V damper actuator works with most standard 24VAC zoning panels that output a consistent signal for damper positioning.

Can this be used for both residential and commercial bypass dampers?
Yes, it is suitable for any high-volume bypass or zone damper application that matches the torque requirements and 24-volt electrical specifications of this model.

Does this actuator require any specialized calibration?
Once securely mounted to the damper shaft and wired to the 24V controller, it typically follows the positioning signals provided by the master zoning board without extensive field calibration.
