Flow Setter Valve:

Each radiator is equipped with a flow 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 flow balancing.

Flow Balancing:

Flow balancing is done by adjustment of the ring marked
1-7 and N on the flow setter valve, lining the desired
setting up with the dimple in the first ring. Turning of the
ring adjusts the diameter available for water flow. 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 flow rate and setting of the flow setter.
