Siemens Building Technology SFA11U Actuator
The Siemens SFA11U Actuator is a line-voltage, 120V normally closed zone valve actuator designed for high-precision control in hydronic heating and cooling systems. Engineered for seamless integration with the Siemens 599 Series zone valves, this 2-position spring return actuator features a 1/10-inch (2.5 mm) stroke and provides 24 lb (105 N) of nominal force to ensure positive valve closure. The SFA11U is UL listed for plenum installations, making it suitable for high-occupancy commercial projects and VAV terminal units. Contractors favor the direct-coupled mounting system which allows for installation without tools, significantly reducing labor time on the job site. A manual override handle with a 3mm hex latch and a clear visual position indicator allow for easy system balancing and troubleshooting during commissioning. With a rapid 10-second positioning time and 9.8 VA power consumption, this Siemens 120V actuator delivers reliable fail-safe operation in fan coil units, floor heating manifolds, and baseboard radiation systems.
Key Benefits:- Direct-Coupled Installation: Mounts directly onto Siemens 599 Series valve bonnets without the need for additional tools or complex calibration.
- Mechanical Fail-Safe: Features a robust internal spring return mechanism that ensures the valve returns to the normally closed position upon power loss.
- Plenum Rated: Meets UL requirements for installation in ceiling spaces used for environmental air return.
- Manual Override: Includes a manual positioning handle for system testing and service without requiring electrical power.
- Compact Footprint: Designed for tight mechanical closets and terminal unit enclosures with minimal clearance requirements.
What valves are compatible with the SFA11U?
This actuator is specifically designed for the Siemens 599 Series zone valves, including 2-way and 3-way diverting patterns with a 2.5 mm stroke.
Can this actuator be used in chilled water applications?
Yes, it is suitable for both heating and cooling; however, ensure the actuator is not exposed to dripping condensate and is mounted in an approved orientation.
Does the SFA11U require a specific wiring orientation?
Yes, it requires a 120 VAC supply. Wiring should be run through a junction box and flex conduit within 15 inches of the unit for code compliance.
