Flow Setter Valve:

Each radiator is equipped with a ﬂ ow setter valve

mounted on the same side as the water connections of

the panel radiator. This valve consists of two part integral

components for temperature control and ﬂ ow balancing.

Flow Balancing:

Flow balancing is done by adjustment of the ring marked

1-7 and N on the ﬂ ow setter valve, lining the desired

setting up with the dimple in the ﬁ rst ring. Turning of the

ring adjusts the diameter available for water ﬂ ow. The N

marking indicates a fully open setting; the 1 marking

indicates nearly full restriction. The diagram on page 13

shows the pressure drop across the radiator as a function

of the ﬂ ow rate and setting of the ﬂ ow setter.
