Product Description
Danfoss TWA-V electrothermal (thermal-wax) valve actuator, OEM order code 088H3120. The TWA-V 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 (NC) — the valve is closed when de-energised and opens when the actuator is powered. Supply voltage 24 V AC (50/60 Hz), power consumption 2 W. RAV / VMT connection; fits Danfoss RAV and VMT valve bodies. 0.95 m connecting cable. Enclosure rating IP41. Net weight 0.135 Kilogram. Genuine Danfoss part; technical data quoted verbatim from store.danfoss.com (code 088H3120). OEM P/N 088H3120, EAN 5702420049588.

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