Datasheet

The TWA is a small actuator for electrical on/off controls to activate several types of valves and floor heating manifolds.

The TWA range covers actuators for 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).

NC/S versions with end switch are also available for some actuator types.

The actuator is equipped with a visual position indicator to show the open or closed position of the valve.

The TWA can be connected to the RA, RAVL and RAV-valves from Danfoss. Furthermore versions for valves with Heimeier/MNG/Oventrop M301,5 connection are available.

Other valves must be verified individually to ensure correct valve closing measurement and valve top geometry.
