It is great that the software allows the definition of Control Valve curve to study the performance of the valve.
However, it still needs to include the ability to define the cavitation curve (sigma or Xf) to check if the valve is cavitating or not at different operation conditions.
Similarly for pumps, if we can define the NPSHr curve and the software would calculate the NPSHa and provide warning if the margin falls below a specified margin (that I can define manually) it will show a warning message on the output window.
