TWA

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, RTD, RAVL and RAV-valves from Danfoss. Furthermore versions for valves with Heimeier/MNG/Oventrop M30×1,5 connection are available. Other valves must be verified individually to ensure correct valve closing measurement and valve top geometry.
