Danfoss FHV-A floor-heating regulating combi-valve, OEM order code 003L1001. Combines flow presetting/balancing with a return-temperature limiting function in one 3/4" valve body for single-room low-temperature floor-heating circuits taken off a manifold or two-pipe system. The FHV-A body accepts a Danfoss RA sensor/head (RA 2000 / RA sensors) that throttles the circuit to hold the set return temperature. Drain-flow Kvs 0.8 m³/h, max. differential pressure 6 bar, max. working pressure 6 bar, max. flow temperature 90 °C, balanced test pressure 10 bar. Net weight 0.894 Kilogram. EAN 5702420037721.
