Steel Valve with Air-Vent for Convectors in
Two-Pipe Heating Systems
Application
Code no. and technical
data
The steel valve is designed for welding into
convectors by the manufacturer. The complete valve consists of a steel valve body, an
air-vent and a valve insert with integrated
presetting of max. flow through the convector. The insert has connection for all
Danfoss RA 2000 thermostatic sensors.
The flow capacity of this valve is designed
for conventional two-pipe heating systems.

kv-values indicate the flow volume (Q) in m3/h at a pressure loss (∆p) across the valve of 1 bar.
kv = Q / √∆p. 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.
2)
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.

Presetting
Materials in contact with
water
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 thermo-
▪
static sensor
Find the reference mark
▪
Turn the setting ring until the desired pre-
▪
setting number aligns with the reference
mark.
Presetting can be selected 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.

Pressure pin and valve spring Chrome steel
Air vent/plug Brass
Setting ‘N’ is used when flushing the system.
When the thermostatic sensor is fitted, the presetting is hidden and thus protected against unintended alteration.
To avoid calcification and corrosion, it is important for the composition of the circulating water
to comply with the VDI 2035 guidelines.
