Thermal actuators TWA

The reference product used for this EPD is representative of Thermal actuator TWA-A RA,230V-10m. The production location is the Danfoss plant in Sofia, Bulgaria. See more information on Danfoss Product Store.

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 24 V (SELV*) or 230 V 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.
