With the Bean Animal, the 2nd and 3rd valves are only there to completely isolate those lines during maintenance.
The advantage over a Herbie is thus;
The first line takes full flow as it's completely submerged.
The second, open channel line (with the air line) may take some overage from the first, but has air introduced into it, so it takes no time to handle the overage - there is no purging. When the overflow rises enough to block the end of the air line, the second now becomes full flow.
The third line is there as a last resort/backup.
