Siemens Building Technology S55155-A109 Floating Control
The Siemens Powermite MT Series S55155-A109 is a high-torque electronic valve actuator engineered for precise terminal unit control in demanding commercial HVACR environments. Built for 24Vac floating control applications, this unit delivers a nominal force of 300N (65 lb), making it a reliable solution for managing MT series valves with a 7/32-inch (5.5mm) stroke. As a veteran-grade HVAC 3-position actuator, it features a fail-safe mechanical spring return to ensures the system defaults to a known state during power loss. The Siemens S55155-A109 is UL listed for plenum installations and includes a manual override with a visual LED position indicator for local troubleshooting and commissioning. Its synchronous motor and robust gearing are designed for long-cycle reliability in HVAC floating control loops, providing the accurate positioning required for air handling units and zone valve applications.
Key Benefits:
- High Torque Performance: Delivers 300N force to handle differential pressures in complex valve assemblies.
- Mechanical Fail-Safe: Integrated spring return provides critical system protection during power interruptions.
- Plenum Rated: UL listed for safe installation in ceiling spaces and air handling compartments.
- Manual Override: Allows for hand-positioning and local override via a manual adjuster for system testing.
- Compact Footprint: Designed for easy integration into tight mechanical closets and terminal unit enclosures.
Common Questions:
What is the maximum stroke compatible with this actuator?
The Siemens S55155-A109 is specifically designed for terminal unit actuators requiring a 5.5mm (7/32-inch) stroke, common in Powermite MT series valves.
Does this unit support 0-10V modulation?
No, this model is a 3-position floating control actuator. It operates using increase/decrease signals rather than a proportional DC voltage signal.
Can I install this actuator in a plenum space?
Yes, this Siemens building technology part is UL listed for plenum installations, meeting standard building codes for air-side equipment.
