Darned if you're not right, Wade. I don't deal with rotary vavles that much and didn't look at my own examples here carefully enough. Still, 135+45 deflection amounts to a heckuva lot more disturbance than 45 degrees.
Here's a photo of another straight-through valve that's found on some trumpets and used to be used on Cuesnon tubas.
