Danfoss TWA-L electrothermal actuator, 24 V AC, normally open (088H3131)

Part Number
088H3131 · HS 8481.90

Danfoss TWA-L electrothermal (thermal-wax) valve actuator, OEM order code 088H3131. The TWA-L 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 24 V AC (50/60 Hz), power consumption 2 W. RAVL connection; fits Danfoss RAVL valve bodies. 0.95 m connecting cable. Enclosure rating IP41. Net weight 140 Gram. Genuine Danfoss part; technical data quoted verbatim from store.danfoss.com (code 088H3131). OEM P/N 088H3131, EAN 5702420050164.
