TWA Standard Actuators



The thermal actuator TWA 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.
TWA actuators can be provided with connections for Danfoss RA, RAVL and RAV valves, as well as for valves with M30x1.5 connection..
TWA actuators are 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).
