TWA Standard Actuators

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.
