Application
Model D Model H
RA-N 013G7370 / RA-U 013G7371 RA-N 013G7390 / RA-U 013G7391
Integrated valves types RA-N 013G7370 and RAU 013G7371, both with built-in presetting, are
designed for incorporation into valve radiators
from different radiator manufacturers.
The two valve types can be recognised by the
colour of the presetting ring:
Red: RA-N,
▪
Yellow: RA-U.
▪
Integrated valves can be used in one and two
pipe installations with circulating pump.
Integrated valves model D can be incorporated
into valve radiators from the following
manufacturers: Alarko, Arbonia, Barlo, Baufa,
Biasi, Brugman, Brötje, Buderus, Cetra, CICH,
DéLonghi (Radel), Finimetal, Hudevad, Northor,
Potterton Myson, Ribe (Rio), Schäfer, Termo

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)
The kv-values indicate the flow volume (Q) in m³/h at a pressure loss (∆p) 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 table shows the average
measured values for integrated valves with radiator. 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).
