Valve replacements, did I get a bad one?

I plan to replace three that are leaking - two are 1" and one is 1 1/4". As I hope you can see in the photos (all handles are turned to full open), the two 1" valves open all the way to where the inner plate seats at top of bonnet.
The 1 1/4 does not. It's at least a 1/4" if not 3/8 away from seating.
Is this "fully open"? Did I get a faulty valve?

    I've got a couple new 1.25 steam valves too. They are American made and they only open that far too, by design. The housing would have to bell out further for the disc plate to turn further up.

    I agree with Fred, it seems fine. It may be that the little 1” valves have to be made to open more to provide enough space for steam and condensate flow
