Flow director
The Danfoss flow director is designed to be used with integrated valves type RA-N 013G1382 for incorporation into aluminium or bi-metal segment radiators from different radiator manufactures.
Aluminium and bi-metal segment radiators are constructed by a series of elements, which are joined together with nipples. The first segment is used as inlet pipe, while return is through the bottom of the second segment.
When integrated valves are used with segment radiators, the flow needs to be directed correctly through the valve to avoid noise problems. This is made with the flow director.

1)The technical differential pressure indicates the upper limit for a proper valve function. In most twopipe systems the recommended differential pressure is sufficient. In order to achieve a noiseless function we recommend in smaller systems to apply automatic bypass valves or automatic balancing valves. If pump differential pressure exceeds the recommended max. valve differential pressure it is recommended that an automatic balancing valve type ASV-P/PV is added to the system.

2)kv-values indicate the flow volume (Q) in m³/h at a pressure loss (Δp) across the valve of 1 bar ;
. At setting N, the kv-value in accordance with EN 215 can be stated as Xp = 2 K. At lower preset values, Xp will be reduced until approximately Xp 0.5 at presetting 1. The kvs values indicate the valve capacity, when the valve is fully open.
3)When using a liquid filled radiator thermostat e.g. RAW, RAS-D or remote setting element type RA 5060, Xp will be increased by factor 1.6 (at setting N, ref. EN 215).
