Cavitation with a ball valve

Hello everyone, my name is Marco, I'm a Mechanical Engineer to be and I'm currently working on a ball valve project. This valve works with water so I'm verifying the cavitation model and here occurs my problem: I'm running a simulation and at 1000 iterations (0.125 travel) it doesn't cavitate yet, even though there's a strong deltaP between inlet and outlet and I'm sure it has to cavitate. I know it is not a whole travel, but with all the other cavitation projects I did, the phenomenon started really soon! I modified all the calculation control options as tutorial said and my mesh is really well refined through appropriate volumes...so I don't know what's wrong. Could somebody help me out please?

Thank you in advance
