The Siemens S55180-A150 is a floating fail-safe actuator engineered for use with Siemens MZ series valves in commercial HVAC and building automation applications. Designed to deliver precise, responsive control, this actuator features a built-in fail-safe mechanism that automatically returns the valve to a predetermined safe position upon loss of power or control signal — protecting system integrity and occupant comfort during power interruptions or control failures.
Key Features
- Fail-safe operation returns valve to safe position on power or signal loss
- Floating (tri-state) control signal for accurate, incremental valve positioning
- Designed for compatibility with Siemens MZ series valve bodies
- Compact, robust construction suited for commercial HVAC environments
- Supports reliable building automation and zone control integration
- Manufactured by Siemens Building Technologies to stringent quality standards
Application
The S55180-A150 is ideal for heating, cooling, and ventilation systems where dependable valve actuation and fail-safe protection are critical. It integrates seamlessly into building automation systems (BAS) and direct digital control (DDC) environments, making it a trusted choice for commercial HVAC contractors and building engineers.
