Performance flow rate characteristics
The graph shows the pressure drop created by the valve itself at different flow rates. It
allows predetermining 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.
