Hi Klara
I understood your problem, I just giving you suggesttion.
Am not sure just add a parameter (opr.Pressure) in all valves, and modify .ptd file (with: "sch_rate", "size", "end_type","opr_pressure")
If you created valves using family table? Just insert parameter into family table and modify
I hope it will be solution.
