Although maybe in order to get this you'd need to connect it "backwards" and it would then be venting all of the time, so it practice it couldn't really be used incorrectly. I'm just curious if anyone has found a useful application for these.
I agree that the quick exhaust valves are a nice way to vent a cylinder without needing to push air back through the solenoid.

The 3 way exhaust valves are useful for isolating a system during maintenance etc. They aren't very useful during a match in my opinion but I could be wrong. You could have a 3 way exhaust valve in front of the solenoids you use to fire a pneumatic catapult. When turned closed the air going to the catapult would be exhausted and the rest of the system would still function but the catapult would be disabled.
