Then the large cylinder will extend much more rapidly than it would have without the latch because the extension speed will not be dependent upon the air flow through the solenoid. It is basically a way to get around the air flow problem that many people experience with the solenoid.
If you want a more detailed explanation we did something like this on our 2010 bot. PM me and I can try to explain it better.

Cam,
The cylinder moves out to the machanical stop but it doesn't have any higher pressure air or greater volume. When the mechanical stop is removed, air still needs to flow behind the piston and that air passes through the fittings as if the primary valve was opened. Or am I missing something?
