Hayseed, a 4" valve is a hell of a lot bigger than two 2" valves.

Diameter does not equal area.

Yep, hotwired has got it on the money. It would actually take 4-2" valves to equal the same as one 4". Since a 4" valve would be super expensive you're best bet would either make a pneumatic piston for a butterfly valve or, as I said earlier, make two 3" valves.
