Siemens Building Technology S55180-A151 Actuator
The Siemens Building Technology S55180-A151 (Model SSB161.05U) is a high-precision electromotoric actuator engineered for the technical demands of HVAC building automation systems. This non-spring return actuator is purpose-built for proportional control in zone valve applications, specifically designed to integrate with Powermite 599 MZ Series globe valves. Operating on 24VAC/DC power, it utilizes a 0-10VDC control signal to provide a linear stroke of 5.5mm with a nominal force of 45 lb (200 N), ensuring reliable modulating operation for fan coil units, chilled ceilings, and VAV terminals.
Designed for fail-in-place performance, this unit maintains its position during power outages, making it ideal for systems where sudden valve closure is undesirable. The direct-coupled installation requires no specialized tools, featuring a universal bonnet and a 3mm hex wrench manual override for commissioning or emergency positioning. With a UL plenum rating and LED status indication for diagnostics, this actuator provides the robust performance veteran contractors expect for hydronic HVAC and thermal management applications.
Key Benefits:- Precise Modulating Control: Uses a 0-10VDC signal for proportional positioning in commercial HVAC systems.
- Direct-Coupled Versatility: Compatible with Siemens Powermite 599 MZ Series valve assemblies without requiring tools for mounting.
- Fail-In-Place Security: Holds last known position during power loss to prevent system pressure shocks.
- Integrated Diagnostics: Features LED visual position indication for rapid field troubleshooting and calibration verification.
- Compact & Durable: Minimal footprint design suitable for tight enclosure plenum installations with a 45 lbf output.
How does the S55180-A151 handle power loss compared to spring-return models?
Unlike spring-return actuators that force a valve into a "fail-safe" open or closed position, the S55180-A151 is a fail-in-place actuator. Upon loss of 24V power, the internal gears hold the valve stem in its current position. Once power is restored, the unit resumes following the 0-10V control signal provided by the controller.
