Actionneurs électrothermiques

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.

ABRA-A5

The ABRA-A5 ON/OFF zone valve actuator has been specifically designed for use with Danfoss RA2000, RA-C, and RA15/6 series of valves used for heating and cooling applications. Additional base adapters are offered for the potential use of the ABRA-A5 to other non-Danfoss valve bodies.

Actuator ABNM A5 LOG/LIN

The ABNM A5 0-10V thermal actuator has beenspecifically designed for use with AB-QM valvesDN10-32/½-1¾ inch in heating and coolingapplications.

​​​​​​​Control is done by a 0-10 V signal, which is provided either by a room thermostat or, in most cases, by a central direct digital control(DDC) system. The actuator converts the 0-10 V signal into a proportional actuator travel, which logarithmic / equal percentage (ABNM A5 LOG).For fan coil unit or chilled ceiling application choice of logarithmic version is recommended (water to air heat exchanger). The result will belinear system response and thus optimal room temperature control.

Thermot

The Thermot is a small actuator for electrical on/off control, designed to operate M30 x 1.5 valves and floor heating manifolds.
The Thermot range includes actuators for 24 V (SELV*) or 230 V supply, available in both normally closed (NC) and normally open (NO) versions (valve positions with no supply voltage to the actuator).
Each actuator is equipped with a visual position indicator to show whether the valve is open or closed.
The Thermot (M30×1.5) can be connected to Heimeier, MNG, and Oventrop valves.
Other valves must be verified individually to ensure correct valve closing dimensions and valve top geometry.

TWA

The TWA is a small actuator for electrical on/off control, designed to operate various types of valves and floor heating manifolds.
The TWA range includes actuators for 24 V (SELV*) or 230 V supply, available in both normally closed (NC) and normally open (NO) versions (valve positions with no supply voltage to the actuator).
NC/S versions with an end switch are also available for certain actuator types.
Each actuator is equipped with a visual position indicator to show whether the valve is open or closed.
The TWA can be connected to RA, RAVL, and RAV valves from Danfoss. The TWA‑K version (M30×1.5) can be connected to Heimeier, MNG, and Oventrop valves.
Other valves must be verified individually to ensure correct valve closing dimensions and valve top geometry.
