Product Range

/The thermal actuator TWA range is used with electrical on/off-controls to activate several types of valves and floor heating manifolds. The actuator is equipped with a visual position indicator to show the open or closed position of the valve. The TWA-actuator can be connected to the RA, RAVL and RAV valves from Danfoss. Furthermore versions for valves with M30x1.5 connection are available. The actuator is made for either 24 V (SELV) or 230 V supply in both normally closed (NC) or normally open (NO) versions (valve positions with no supply voltage to the actuator). Furthermore the 24 V actuator for RA valves also comes in a NC/S-version having an end-switch.

Application flexibility

Application flexibility

Thermo-hydraulic actuators provide application flexibility, connecting the specific valve and valve actuator configuration to meet the exact requirements.

The Danfoss range of actuators;
- TWA thermal wax actuator can be used with electrical on/off-controls to activate several types of valves and floor heating manifolds.

- ABNM thermo-electric actuator is controlled by a 0-10 V signal, which is provided either by a room thermostat or by a central DDC system.
