Danfoss TWA-A electrothermal actuator, 24 V AC, NC with end-switch

Danfoss TWA-A electrothermal (thermal-wax) valve actuator, OEM order code 088H3114. The TWA-A converts a switching signal from a room thermostat or controller into valve movement on hydronic floor-heating manifolds and radiator/zone valves — no auxiliary air or hydraulics. Normally closed with auxiliary end-switch (NC/S) — closed when de-energised, opens when powered; the built-in end-switch signals the open/closed position. Supply voltage 24 V AC (50/60 Hz), power consumption 2 W. RA snap-on connection; fits Danfoss RA valve bodies and RA-connection manifold valves. 0.95 m connecting cable. Enclosure rating IP41. Integral end-switch for open/closed feedback. Net weight 0.134 Kilogram. Genuine Danfoss part; technical data quoted verbatim from store.danfoss.com (code 088H3114). OEM P/N 088H3114, EAN 5702420049625.
