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, RAS- C, 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).

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.

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.

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 without Radiator and Fittings
