Siemens Valve Actuator, 25s Maximum Closing Time, 24V Supply Voltage - S55180-A110


This valve actuator is an electromotoric device designed to automate control valves in building services and industrial automation. It operates from a low-voltage control supply and is suitable for integration into HVAC and electrical control systems where motor-driven valve positioning is required.

Features and Benefits:


• 24V supply enables safe low-voltage installation and control
• 25s maximum opening time provides predictable stroke timing
• 25s maximum closing time ensures consistent response on shutdown
• 2.5VA power draw minimises load on control circuits

Applications


• Suitable for central heating valve control in commercial buildings
• Ideal for integration with building automation HVAC controllers
• Used for retrofit replacement of older motorised valve drives
• Can be used for fluid flow modulation in plantroom pipework

What supply considerations are needed for mains control panels?


It requires a 24V control supply and draws 2.5VA, so panel transformers and fusing should be sized to accommodate that continuous power demand and any concurrent actuator loads.

How quickly will the actuator move a valve through its stroke?


The actuator completes both full opening and full closing within 25s under nominal conditions, allowing synchronous timing with system controls.

Is this actuator suitable for commercial replacement projects?


Yes, it is specified for 24V valve control and is compatible with common commercial valve control infrastructures, facilitating direct substitution where electrical characteristics match.
