Flow director

The Danfoss flow director 013G1526 is designed to be used with Danfoss integrated valve type 013G1382 for incorporation into tube segment radiators.

Tube segment radiators are constructed by a series of elements, which are welded together. The first segment is used as inlet pipe, while return is through the bottom of the second segment.

When integrated valves are used in tube segment radiators, the water flow needs to be directed correctly through the valve to avoid noise problems. This is made with the Danfoss flow director.

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)kv-values indicate the flow volume (Q) in m³/h at a pressure loss (Δp) 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. If a remote temperature adjuster is used, the P-band is increased by a factor of 1.1. If a liquid filled radiator thermostat is used, the P-band is increased by a factor of 1.6.
