pressure seal bonnets acc to ASME B16.34

[Raaden]

Hi!

I'm going to design a valve acc to ASME B16.34, so how can I calculate the P.S.B. on the valve?
I have only found a way of calculating bolted bonnets in B16.34, so is there another ASME standard out there that has a way of calculating pressure seal bonnets?

There is a great calculating method in EN 12516-2 chapter 9, but is it ok to use that one on an ASME-valve?

Thanks

As far as i know neither ASME nor API addresses this issue. Thanks for EN info.
