Siemens Building Technology SAS61.03U Actuator
The Siemens SAS61.03U Actuator is a high-performance non-spring return electronic valve actuator engineered for modulating control in HVAC systems. Designed for a 24V supply (AC or DC), this unit provides a reliable 400N (90 lbf) positioning force for Siemens Powermite 599 Series terminal unit valves with a 7/32-inch (5.5 mm) stroke. This modulating valve actuator utilizes a 0-10 VDC or 4-20 mA positioning signal to deliver precise, stepless motor control, ensuring optimal flow regulation in both liquid and low-pressure steam applications. With a fast 30-second run time and an integrated manual positioning knob, technicians can easily perform commissioning and field adjustments. The SAS61.03U features a maintenance-free reversible motor, auto-calibration for stroke detection, and a position feedback signal (0-10 VDC) for real-time monitoring via the building automation system. The NEMA 1 housing is UL listed for plenum installations, supporting robust HVACR valve control in demanding commercial environments.
Key Benefits
- Fast Response Time: Features a 30-second positioning time for rapid system adjustments and improved climate control.
- High Compatibility: Direct-mount design specifically for Siemens Powermite 599 Series MT terminal unit valves.
- Fail-in-Place Reliability: The non-spring return (NSR) logic maintains the last commanded valve position during a power loss.
- Technical Precision: Integrated auto-calibration automatically detects the valve seat to ensure exact stroke management.
- Contractor-Friendly Installation: Includes a manual override knob with a position indicator and a 0-10V feedback signal for simplified troubleshooting.
Common Questions
How do I wire the SAS61.03U for 4-20 mA control?
The actuator is field-configurable via internal DIL switches. To use a 4-20 mA signal instead of the factory-default 0-10 VDC, adjust the specific switch according to the Siemens technical instructions (Document 155-682).
Can I install this actuator in a steam application?
Yes, the SAS61.03U is rated for low-pressure steam; however, the actuator must be mounted between 45 degrees and the horizontal plane to prevent thermal damage to the electronics from rising steam.
What valves are compatible with this actuator?
It is designed for use with Siemens Powermite 599 Series terminal unit valves (2-port and 3-port) featuring a 5.5 mm stroke length and a 7/16-inch threaded connection.
