Semi-lug Butterfly Valve Bolting

Hi guys,

I need to create a butterfly valve in the semi-lug style. Is it possible to have some of the bolts go all the way through like a wafer and some of them not go all the way through so they are calculated for each side? Using new bolting method here.

What COCO would I use? WFBB or FBB for example. Starting to think maybe Aveva cannot do this.

Thanks for any help.

it can. there is an example in the user manual.

Thank you! So it is possible.

You still have to consider it a wafer item but give a value of 0 for the bolt length for those numbers which do not pass through, in the mating flange.
