Product Description
Danfoss RA-N — thermostatic radiator valve body with presetting for two-pipe hydronic heating systems, OEM order code 013G0056. The RA-N (normal flow) valve body accepts an RA-series thermostatic sensor (RA 2000 / living-eco head) or an actuator on its clamp connection; the integral presetting device limits the design flow per radiator so the system self-balances without a separate balancing valve. Presetting is stepped 1…7 plus fully open (N), read on the scale under the head. Nickel-plated brass body, straight pattern. (RA-N DN 20, straight, dimension standard S.) Nominal size DN 20, connection Rp 3/4 (inlet) / R 3/4 (outlet, external for tailpiece), 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 Metric thread. Application: 2-pipe system. Net weight 0.416 Kilogram. Genuine Danfoss part; technical data quoted verbatim from store.danfoss.com (code 013G0056). OEM P/N 013G0056, EAN 5702420011394.

Compatibility & Fitment
Two-pipe radiator valve body for DN 20 straight connection (Rp 3/4). Accepts a Danfoss RA-series thermostatic sensor (RA 2000 / living eco) or thermal/electric actuator on the valve clamp ring; set the presetting to the design flow of the radiator. Confirm design (Straight), nominal size (DN 20) and dimension standard (S) against the installation before ordering.
