Danfoss RA-NCX DN 15 double angle left design-radiator valve — integrated presetting, Chrome (013G4240)

Danfoss RA-NCX design-radiator valve, DN 15, OEM order code 013G4240. A normal flow radiator valve body with integrated pre-setting for design/panel radiators, in a double angle left pattern. The stepped presetting (settings 1-7 + N) limits the design flow per radiator so a two-pipe system self-balances without a separate balancing valve; the valve accepts an RA-series thermostatic sensor on the clamp connection. 2-pipe system. Connection Rp 1/2 (inlet) / R 1/2 (outlet). Kvs 0.9 m³/h m³/h, max. working pressure 10 bar, test pressure 16 bar, flow temperature up to 120 °C. Chrome plated. Genuine Danfoss part; data quoted verbatim from store.danfoss.com (code 013G4240). OEM P/N 013G4240, EAN 5702420072173. HS 8481.80.
