28" 900# Ball Valve--Where I can get them?

I am working on a part of a subsea pipeline on the offshore platform however as per P&ID I need to have a 28" 900# Ball Valve. I searched for the standards & came to know that ASME B16.10 covers the size only upto 24" only then what can be done to get to know the dimensions of this big valve. I am unable to manage the available small space properly on the platform without this information.

Pipeline guys must be knowing about it as they deal with large dia pipelines all the time.

Pls help.

Thanks for your help.
