Danfoss Integrated Valve with Presetting Data sheet

Data Sheet

Integrated Valve with Presetting for Manifolds in Two-Pipe Heating Systems

Product

The integrated valve is designed for manifold

applications in combination with a system

connection piece.

Valve and connection piece are fitted to top and

bottom of manifolds with ½” connections.

The valve has RA 2000 connection for Danfoss

sensors and TWA thermal actuators.

The valve features an integrated presetting of

max. flow, which allows each heating circuit to be

balanced independantly.

Flow capacity is designed for conventional two-

pipe heating systems. The valve is mounted in

the return flow.

Application

Floor heating manifold with integrated valve 013G0376 and TWA thermal actuator in return flow.

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.

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 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. Setting ‘N’ is used when flushing the system.

When the sensor or the actuator is fitted, the presetting is hidden and thus protected against unintended alteration.
