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,

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).

Presetting
Capacities at Xp = 2K with Danfoss radiator thermostat RA 2000 are measured without radiator and
connection fittings.
1. Presetting range
2. Factory setting and one-pipe system
3. Reference mark
Presetting can be selected infinitely variably
within the range of 1 to 7. At setting ‘N’ the valve
is fully open. Setting in the shaded areas of the
drawing should be avoided.
The presetting values of the integrated valve can
be adjusted easily and accurately without the use
of tools (factory setting: N):

Mounting Instructions
Installation of an integrated valve at radiator
manufacturer’s plant
An integrated valve can only be fitted once in a
radiator (because of the load on the deformation
zone).
Fit the integrated valve in the radiator using
▪
a 12-edge spanner, KW 21.
Tighten using a torque of 30-35 Nm
▪
If required, continue turning until one of the
▪
cap thread beads points upwards (only
clockwise). Tolerance for adjustment: ±5°.
Removal and fitting in an existing radiator
1. Two O-rings
2. Reference mark
Before removal: Notice the presetting value.
▪
Please mark off the valve position on the
▪
valve and the radiator (3), e.g. on top (4)
Remove valve.
▪
Fitting: Insert the integrated valve, tighten
▪
until the marked-off position has been
reached.
Setting ring with presetting numbers (5):
Red: RA-N
▪
Yellow: RA-U
▪
Replacing the Gland Seal
While the system is in operation, the gland seal can be replaced by means of a spanner, KW 10. Hold
the setting ring using a 12-edge ring-spanner, KW 17.
