On each of the ARV Vario ProClick 3-way mixing valves there is a nameplate with three marked Kvs coefficent values.

In addition, it is also possible to select intermediate values between these values.

The diagrams below show a simplified way of selecting the Kvs value for each valve size. If the selected valve has

a pressure drop value of less than 3 kPa at the minimum Kvs value, select a valve with a smaller diameter and for

this determine the required Kvs. If the pressure drop value is bigger than 15 kPa at the maximum Kvs value, select

a valve with a larger diameter and for this determine the required Kvs.

The procedure for Kvs selection is described in detail in the valves manual in chapter:
