THERMAL ACTUATOR TWA-A/NC/230V

TWA is a small actuator designed for electrical open/close control, used to operate various types of valves and underfloor heating distribution manifolds. The actuator features a visual position indicator showing whether the valve is open or closed. The TWA range includes actuators for 24 V (SELV) and 230 V, available in normally closed (NC) and normally open (NO) versions (valve position with no voltage applied to the actuator). Additionally, the 24 V TWA actuator for RA valves is available with a limit switch (NC/S version). TWA can be connected to Danfoss RA, RTD, RAVL, and RAV valves. Additionally, models are available for Heimeier, MNG, and Oventrop valves with M30 × 1.5 connection. Other valves must be checked individually to ensure proper valve closing dimension and upper valve geometry. Features
