Integrated Presetting Valves, Type RA-N 013G3390
- for Normal Volume Flows
Application
Code Nos. and Technical
Data
Integrated valves type RA-N 013G3390 with builtin presetting are designed for incorporation into
valve radiators from different radiator
manufacturers.
The valve can be recognised by a red presetting
ring.
The valve is to be used in single and two pipe
installations with circulating pump.
The gland seal of the valve can be replaced while
the system is in operation.

To avoid calcification and corrosion, it is
important for the composition of the circulating
water to comply with the VDI 2035 guidelines.
Danfoss thermostatic sensors type RA 2000, RASC, RAS-D and RAE with patented snap sockets as
well as Danfoss thermo-hydraulic actuators can
be installed directly onto the integrated valve.

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. RAS-C, RAS-D, RAE or remote setting element type
RA 5060 Xp will be increased by factor 1.6 (at setting “N”, ref. EN 215).

2. Factory setting and one-pipe system
3. Reference mark
The presetting values of the integrated valves
can be adjusted easily and accurately without the
use of tools (factory setting: ‘N’):
Remove the protective cap or the
▪
thermostatic sensor
Find the reference mark
▪
Turn the setting ring until the desired
▪
presetting aligns with the reference mark.
The presetting is controlled directly without the
use of equipment. After installation in the
radiator, the reference mark of the valves will not
always be positioned in the same place.

Capacities without Radiator
and Fittings
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.
In a one-pipe installation, the setting ‘N’ must be
used.
Setting ‘N’ can be used as a flushing position if
the system has to be flushed out because of dirt
problems.
RA-N 013G3390
When the radiator thermostat has been installed,
the presetting is protected against unintended
regulation.
For Danfoss elements RA 2000, RAS-C, RAS-D and
RAE, a theft protection device is available; this
also provides added security against unwanted
adjustment of the preset values.
Capacities at Xp = 2K with Danfoss radiator thermostat RA 2000 are measured without radiator and
connection fittings.

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):
RA-N types: Red plastic
▪
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.
