With the caveat that the full throttle valve empties into the same wells as the metering jets, thence through the venturi cluster into the air stream just like idle to WOT.
The full throttle valve is basically like switching to larger jets on the fly.
It is not a separate circuit. Valve bypasses the jets, from the bottom of the same fuel bowl (it's located between them), then empties right back in on the other side.
