Then would you also allow these valves? They contain check valves, but one is a flow control valve, and one is a shuttle valve. There is no rule that specifically allows a flow control (unless it was in a previous year's KOP, and there were some) or a shuttle valve (yes, you could make one from two check valves and a tee). The rule says only the items listed below can be used, and I don't see a listing for quick exhaust valves, flow control valves, or shuttle valves. I am sure there are many other valve types that contain check valves that could be found as well.

I am not arguing against quick exhaust valves, I love them, and have had many application in FIRST where I would liked to have used them, but the way the rules are written, I don't see an interpretation that allows them. remember what the manual says about intent:

The intent of this manual is that the text means exactly, and only, what it says. Please avoid interpreting the text based on assumptions about intent, implementation of past rules, or how a situation might be in “real life.” There are no hidden requirements or restrictions. If you’ve read everything, you know everything.
