York S1-SFA71UG Actuator
The York S1-SFA71UG Actuator is a field-proven, 2-position control solution designed for precision airflow and fluid regulation in commercial and residential HVACR environments. This Normally Closed (N/C) electronic actuator operates on a standard 24VAC Class-2 supply signal, ensuring seamless integration with existing low-voltage control circuits. Engineered to interface directly with zone valves featuring a 1/10-inch stroke, the S1-SFA71UG provides reliable spring-return fail-safe functionality, automatically returning to the closed position upon power loss to protect system integrity.
For technicians in the field, this direct-coupled actuator eliminates the need for specialized tools during installation and features a manual override handle with an auto-unlock mechanism for simplified commissioning. The unit offers a 10-second run time and consumes a nominal 9.8 VA, making it an efficient choice for high-density zone applications. With a robust build weighing in at 1.22 lbs and UL listing for plenum installations, the York S1-SFA71UG is the professional standard for replacing or upgrading legacy zone control actuators in hydronic or air-side systems.
Key Benefits for the Contractor- Standard 24VAC Compatibility: Easily integrates with 24-volt control systems without requiring additional step-down transformers.
- Direct-Coupled Installation: Mounts directly to valve bonnets or damper shafts, reducing labor time and potential for linkage failure.
- Normally Closed Fail-Safe: Reliable spring-return action ensures valves or dampers close securely during power interruptions.
- Manual Override with Auto-Unlock: Allows for physical positioning during system charging or testing, which automatically disengages once power is restored.
- OEM Fit and Finish: Optimized for York HVAC systems to prevent the alignment and torque issues often found with generic alternatives.
Is the S1-SFA71UG compatible with 120V systems?
No, this specific model is designed for 24VAC Class-2 circuits. Utilizing higher voltages will damage the internal electronic components.
Can this actuator be mounted in any orientation?
While the actuator supports multiple positions, vertical mounting is recommended to prevent water infiltration from condensation on piping.
Does the unit include visual position feedback?
Yes, the actuator features a built-in visual indicator to verify the open or closed state of the zone valve or damper quickly.
