Danfoss TWA-A electrothermal actuator, 230 V AC, normally open (088H3113)

Danfoss TWA-A electrothermal (thermal-wax) valve actuator, OEM order code 088H3113. 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 open (NO) — the valve is open when de-energised and closes when the actuator is powered. Supply voltage 230 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. Net weight 0.12 Kilogram. Genuine Danfoss part; technical data quoted verbatim from store.danfoss.com (code 088H3113). OEM P/N 088H3113, EAN 5702420050140.

Electrothermal actuator for Danfoss RA valve bodies and RA-connection manifold valves. Signalled by a 24 V or 230 V AC room-thermostat/controller output — match the supply voltage (230 V AC) and valve function (normally open) to the control system. Confirm the valve connection (RA) against the manifold or valve body before ordering.
