York S1-M9205-GGA-YK10 Actuator

The York S1-M9205-GGA-YK10 Actuator is a professional-grade spring return damper actuator designed for precise proportional control in commercial HVAC systems. Operating on a 24 V AC/DC power supply, this direct-mount unit delivers a 44 lb-in stall torque and 27 lb-in driving torque, making it a reliable solution for managing airflow regulation in air handlers and ventilation units. Engineered with a brushless DC motor and microprocessor control, it ensures a constant 90-second runtime regardless of load, preventing motor burnout during high-resistance operation. The actuator accepts a 2-10 VDC control signal and provides a matching 2-10 VDC position feedback signal for integrated building automation monitoring. Its versatile design supports direct-coupled mounting to round shafts up to 1/2 inch or square shafts up to 5/16 inch, eliminating the need for complex linkages. The rugged construction and electronic stall detection safeguard the York replacement part against mechanical overload, ensuring consistent performance in demanding environmental air-handling applications.

• Precise Proportional Modulation: Responds to 2-10 VDC or 4-20 mA (with 500-ohm resistor) signals for accurate damper positioning.
• Fail-Safe Reliability: Integrated mechanical spring return ensures the damper returns to the home position during power loss.
• Simplified Installation: Features plenum-rated cables and a self-centering shaft coupler for rapid field setup.
• Durable Brushless Motor: Microprocessor-controlled DC motor maintains speed and provides electronic stall protection without mechanical end switches.
• Flexible Mounting: Bidirectional design allows for clockwise or counterclockwise operation to suit various HVAC damper configurations.

What is the primary application for this York actuator?
This actuator is specifically designed for modulating control of dampers in HVAC systems, including VAV boxes and air handling units where precise airflow management is required.

Does it require an external ground connection?
No, the York S1-M9205-GGA-YK10 features double-insulated construction, eliminating the need for a separate electrical ground for regulatory compliance.

Can I use this for larger industrial dampers?
This model provides 27 lb-in of driving torque. For larger dampers, verify the square footage and torque requirements; you may need to parallel multiple units or select a higher-torque actuator.
