Product Description
Danfoss RA-FN — thermostatic radiator valve body (fixed capacity, no presetting) for two-pipe hydronic heating systems, OEM order code 013G0028. The RA-FN (fixed capacity) valve body is the non-presettable version of the RA-N: it accepts an RA-series thermostatic sensor (RA 2000 / living-eco head) or an actuator on its clamp connection and gives a fixed Kv per nominal size, so radiator flow is set solely by the thermostatic head. Use where individual branch presetting is not required. Nickel-plated brass body, straight pattern. (RA-FN DN 25, straight, dimension standard D.) Nominal size DN 25, connection Rp 1 (inlet) / R 1 (outlet), Kvs 1.4 m³/h, max. working pressure 10 bar, test pressure 16 bar, max. differential pressure 0.6 bar, flow temperature up to 120 °C. Finish Nickel plated; tailpiece Standard. Application: 2-pipe system. Net weight 0.636 Kilogram. Genuine Danfoss part; technical data quoted verbatim from store.danfoss.com (code 013G0028). OEM P/N 013G0028, EAN 5702420004150.
