3.1.1. Performance flow rate characteristics
The graph shows the pressure drop created by the valve itself at different flow rates. It allows to
predetermine the maximum flow rate going through the valve depending on the system settings (inlet
pressure etc). It also allows to determine the valve pressure drop at a given flow rate, and therefore
to evaluate the system pressure drop vs flow rate.
