Our team is developing a cannon that uses almost nothing but KOP pneumatics, with the exception being our barrel and its mount.

One question regarding the Festo Single Solenoid valves; where is the documentation for the maximum operating PSI? The FIRST documents only list the minimum, and I cannot find the specs sheet for it through google or on Festo's site.

This depends on the size and length of your barrel. Our team's CanonBot uses a 3" Barrel, 3 feet long. At first we tried the Festo valve at 60 psi, but there's just too much restriction for our application. The sprinkler valve seemed to work the best for us. We use 2 steel tanks which lead to a manual ball valve which acts as our safety. After the ball valve is the sprinkler valve and then to the barrel. We keep safety valve closed except when the robot is in operation and everyone is clear of the robot and the barrel. We usually run our pressure between 60 and 80 psi.
