Integrated valves type RA-N 013G3380 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 two-pipe 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 X
will be increased by factor 1.6 (at setting “N”, ref. EN 215).
The presetting values of the integrated valves
can be adjusted easily and accurately without the
use of tools (factory setting: ‘N’):

Capacities without Radiator
and Fittings
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.
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.
RA-N
Setting ‘N’ can be used as a flushing position if
the system has to be flushed out because of dirt
problems.
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.

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.
