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.
