Data Sheet
Integrated Valve with Presetting for Manifolds in
Two-Pipe Heating Systems
Product
Application
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 twopipe heating systems. The valve is mounted in
the 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.
