Pressure drop diagram
The valves have adjustable kvs value (kvs = the flow in m
3
/h at a pressure drop of 100 kPa).
To draw a curve for other settings than the pre-drawn values:
Draw a vertical line through the flow. The starting point of the angled line is where the vertical line intersects the top of the
chart (at 100 kPa). The angled line should be parallel to the pre-drawn lines.
In the example above, the kvs value = 0.25.

Adjustable kvs value
The kvs value is set by turning the grey plastic cap until the desired number on the cap is aligned with the reference
marking in the valve (see the picture below). Depending on the number selected on the plastic cap, different kvs values are
set according to the table below.
