As a toilet’s water tank fills, water, via a hose, goes into the flush valve at the top. It appears that the bowl fills faster than the tank but water continues to go down into the flush valve all the while filling the tank. Where does the ‘excess’ water go that is being put into the flush valve? Thanks, dlb .

I'm pretty sure it rinses the toilet bowl and fills it up.

What popa said. The fill valve does two things: It fills the tank, but it also has a small bypass that directs a bit of water into the bowl. This ensures that the bowl has sufficient water in it to manage the next "load".
As to where the "excess" water goes: It's impossible to overfill a toilet bowl, as long as the drain is not clogged. Any excess water simply climbs over the trap that is part of the toilet and falls down the drain.
Have a look at the pic....
The water that is excess to that required to fill the bowl goes on down the drain line, once the trap is filled. A lot of the low flow toilets don't actually release enough water to fill the bowl to the weir height.
Thanks for the reply. It appears that after the bowl/trap is filled and the tank has not, water continues into the bowl and into the DWV pipe.
Thanks again,
