Giant ball valve - GIF

[Frank S]

Not a lot of wall thickness and no flange. It's already painted blue so I doubt they'll be installing flanges at this factory. I'm guessing that tiny brass section at the end is the bevel to weld to the next spool of pipe. But since it's so small, I bet this thing has a surprisingly low pressure rating. A kajillion gallons a second at 10 PSI or something.

It is meant to be mounted between 2 special flanges Using many tie bolts
