Product Description
Danfoss TWA-K electrothermal (thermal-wax) valve actuator, OEM order code 088H3105. The TWA-K 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 230 V AC (50/60 Hz), power consumption 2 W. M 30 x 1.5 threaded connection; fits valve bodies and manifolds with the standard M 30 x 1.5 valve thread. 0.95 m connecting cable. Enclosure rating IP41. Integral end-switch for open/closed feedback. Net weight 0.136 Kilogram. Genuine Danfoss part; technical data quoted verbatim from store.danfoss.com (code 088H3105). OEM P/N 088H3105, EAN 5702425123429.

Compatibility & Fitment
Electrothermal actuator for valve bodies and manifolds with the standard M 30 x 1.5 valve thread. Signalled by a 24 V or 230 V AC room-thermostat/controller output — match the supply voltage (230 V AC) and valve function (NC with end-switch) to the control system. Confirm the valve connection (M 30 x 1.5) against the manifold or valve body before ordering.
