Dear all, I was looking around trying to understand what is the state of the art of trunnions check, and I couldn't find any reference to ASME Code cases N-391-2 and N-392-3 on the 2013 version of ASME B&PV Code

I've found them on 2007 version of that code.

Do you know if these code cases are still valid?

Thank you.

Try looking for ASME Section III, Div 1 Nonmandatory Appendix Y. I think they have been incorporated there.
