Any Ball Valve Experts Out There?

Probably nothing but the valve manufacturers will make a cheaper valve without the approval

Correct and much cheaper.

Along a similar line, most Cat 5 Network cable is actually Cat 6, just labeled as Cat 5 because people don't want to pay extra.

Of course to make the connection Cat 6 you need to terminate it according to that spec....
