Danfoss TWA Thermal Actuator Datasheet
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 24V (SELV*) or 230V 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.
*SELV = Safety Extra Low Voltage
