The k
vs
values in bypass B of the 3-port valves represent only 70 % of the k
vs
value in the straight-
through control path AB → A. This compensates for the flow resistance of the heat exchanger or
radiator, so keeping the overall flow rate
100
as constant as possible.
k
vs
= Nominal flow rate of cold water (5…30 °C) through the fully open valve (H
100
), by a differential
pressure of 100 kPa (1 bar)
