Siemens Building Technology SFA71U Acutator
The Siemens Building Technology SFA71U Actuator is a professional-grade 24V N/C 2POS S/R ZoneVlvAct engineered for high-demand hydronic applications. Designed as a normally closed electronic valve actuator, this unit provides 2-position control for Siemens 599 Series zone valves with a 1/10-inch (2.5 mm) stroke. Built for efficient field integration, it features a direct-coupled installation that requires no tools, alongside a manual override and visual position indication for rapid system troubleshooting and manual commissioning. The spring return fail-safe operation ensures critical system protection during power loss, while the UL listed plenum rating allows for flexible mounting in air-handling spaces. With a 105 N nominal force and low 9.8 VA power consumption, this Siemens zone valve actuator is an essential component for maintaining balanced flow in fan coil units, radiators, and radiant manifold systems. Reliable performance is maintained across broad operating temperatures, making it a standard choice for HVAC zone valve control in commercial and residential settings.
Key Benefits
- Tool-Free Installation: The direct-coupled universal bonnet allows for hand-tightened mounting, significantly reducing labor time for the controls contractor.
- Fail-Safe Protection: Integrated spring return mechanism automatically returns the valve to its normally closed position upon power interruption.
- System Visibility: Features clear visual position indication and a manual override handle for immediate status verification and manual system bypass.
- Versatile Application: UL listed for plenum installations, suitable for hot or chilled water systems, including VAV terminals and fan coil units.
Common Questions
- Is the SFA71U compatible with 3-way valves? Yes, the SFA71U is designed to work with both 2-way and 3-way Siemens 599 Series zone valve bodies.
- What is the typical run time for this actuator? This unit features a swift 10-second positioning time for 2-position (on/off) operation.
- Does it require a specific transformer? It requires a 24 VAC Class-2 supply signal and should be powered by an earth-ground isolating, step-down transformer.
