Siemens Building Technology SSD61U Actuator
The Siemens Building Technology SSD61U Actuator is a fail-in-place, non-spring return (NSR) electronic valve actuator designed for high-precision control in 1/2-inch to 1-1/4-inch pressure independent control valves (PICV). Operating on a 24V AC/DC power supply, this 0-10VDC actuator delivers a linear force of >56 lbs (250 N), ensuring reliable modulation of PICV HVAC systems in chilled or hot water applications. This field-proven Siemens electronic actuator features automatic stroke calibration and a direct-coupled terminal connection for rapid, tool-free installation.
Engineered for technical environments, the Siemens SSD61U includes a manual override function and visual position indication for streamlined maintenance. Its proportional control signal integration supports seamless building automation via a 0 to 10 Vdc signal, while the NEMA 1 rated housing is UL listed for plenum installations. This 24V proportional actuator is the standard for maintaining balanced flow and thermal efficiency in closed-loop systems with water-glycol solutions up to 50%.
Key Benefits:
- Precise Flow Control: Optimized for pressure independent control valves to maximize energy efficiency in varied load conditions.
- Efficient Installation: Direct-coupled design and hand-tightened coupling nut allow for mounting without specialized tools.
- Simplified Commissioning: Built-in automatic stroke calibration ensures the actuator matches the valve stroke accurately on power-up.
- Versatile Power Options: Specifically designed to accept both 24 Vac and 24 Vdc power supplies for maximum site flexibility.
- Fail-in-Place Reliability: Maintains the last commanded position upon loss of control signal or power, ideal for specific zone control strategies.
Common Questions:
How do I calibrate the Siemens SSD61U after installation?
This actuator features automatic stroke calibration. Once properly mounted onto the valve and powered, the unit will cycle to its end stops to learn the stroke length. Note that the valve must be connected before applying power to prevent the shaft from reaching a locked maximum extension.
Can I use this actuator with spring return requirements?
No, the SSD61U is a non-spring return (NSR) model. For fail-safe applications requiring a spring return to a normal position upon power loss, the SSD61.5U variant should be utilized.
What valves are compatible with the SSD61U?
This unit is designed specifically for 1/2" to 1-1/4" Siemens 599 Series Pressure Independent Control Valves with strokes of 2.5 mm, 5 mm, or 5.5 mm and a threaded bonnet.
