Description
The Siemens Building Technology S55180-A155 is a 0–10V fail-safe actuator engineered for use with Pressure Independent Control Valves (PICVs) in commercial hydronic HVAC systems. Designed to meet the demands of modern building automation, this actuator combines accurate modulating control with a built-in fail-safe mechanism that returns the valve to a predetermined safe position upon loss of power or control signal — protecting system integrity and occupant comfort.
Key Features
- 0–10V DC modulating control signal for precise, stepless valve positioning
- Fail-safe operation returns actuator to safe position on power or signal loss
- Designed for use with Siemens Pressure Independent Control Valves (PICVs)
- Optimized for variable flow hydronic heating and cooling applications
- Compact, robust construction suited for commercial building environments
- Compatible with building automation systems (BAS) and direct digital controls (DDC)
- Siemens Building Technology quality engineering for long-term reliability
Application
The S55180-A155 is ideal for use in commercial HVAC hydronic systems including fan coil units, air handling units, and terminal units where pressure-independent flow control is required. Its 0–10V input signal makes it directly compatible with most DDC controllers and BAS platforms, enabling seamless integration into intelligent building control strategies.
Why Choose Siemens PICV Actuators
Siemens Building Technology is a global leader in HVAC controls and building automation. PICV actuators from Siemens eliminate the need for separate balancing valves by combining flow limiting, pressure regulation, and modulating control in a single assembly — reducing installation time, improving energy efficiency, and simplifying commissioning.
