Taco Zone sentry question

STEAM DOCTOR

Was looking over the specs for the zone sentries. Seems that the 1" has a lower CV value than the 3/4". Am I missing something? Does that make any sense?

I have wondered this as well. The 3/4" valve seems to have the exact same body and ball as the 1" valve, so it doesn't make any sense to me either.

I don't have these to physically look at them but dimensions seem off too
says 1/2" "F" dimension is the same as the 3/4" but the total length "E" for 1/2" is 1-1/2" longer than 3/4".

Cv is correct, orifice size is the same so when you have more flow through 1” line it creates a higher pressure drop.
