Siemens Valve Actuator, 7W Power Rating, 230V AC Supply Voltage - S55180-A105


This valve actuator provides electromechanical control of zone valves within building services and process systems. It operates from mains supply and is intended for integration into HVAC and automated fluid distribution setups where timed, powered valve positioning is required.

Features and Benefits:


• 230V AC supply enables direct connection to standard mains
• 7W power consumption reduces electrical load
• 67.5s maximum closing time ensures controlled shut-off
• 67.5s maximum opening time allows smooth valve travel
• Conforms to EN 60730 for automatic electrical controls

Applications


• Suitable for motorised control of heating zone valves in HVAC systems
• Ideal for retrofit replacement in existing valve control installations
• Used with building automation panels requiring mains-driven actuators
• Can be used for timed valve operation in commercial plumbing systems

What electrical input does it require for operation?


It requires a 230V AC mains supply compatible with typical UK and EU installations.

How does its power rating affect system design?


The 7W rating permits straightforward load calculation and minimal impact on circuit-breaker sizing and supply-side thermal considerations.

What performance timing should be expected during valve movement?


Both opening and closing actions take up to 67.5s, providing gradual actuation suitable for limiting water hammer and pressure transients.
