ABN-FBH
The ABN-FBH actuator is a thermal wax actuator (TWA) for opening and closing valves on heating circuit manifolds in underfloor heating systems. The actuator has been specially developed for targeted use in the widest variety of systems. Its compact size, design, functionality and flexibility are the most impressive features. A valve adapter concept guarantees the perfect adjustment of the actuator to almost any valve bases and heating circuit manifolds on the market.
The ABN-FBH actuator serves to ensure the optimum control of valves on heating circuit manifolds. Control can be implemented using ON/OFF switching or by applying pulse‑width modulation (PWM).
The ABN-FBH range includes actuators for 24 V (SELV*) (*SELV = Safety Extra Low Voltage) or 230 V supply.
Features and benefits
- Available in Normally Closed (NC) and Normally Open (NO) versions
- First-open function (actuator fully open during installation) for easy installation of the NC actuator; automatically unlocked by applying the operating voltage for more than 6 minutes
- Visual position indicator
- Compatible with a wide range of valves and manifolds using adapters
- Energy-efficient – only 1 W running power consumption
- 360° mounting position – IP 54
- The actuators plug into place once the adapter is mounted on the valve or manifold, enabling quick and tool-free assembly
