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.

I'm not sure you are thinking of the correct valve. I don't see a way to use a quick exhaust to isolate anything. The advantage of the quick exhaust is to allow the air to vent freely in one direction so it doesn't have to go all the way back to, and then through, the valve. That way a cylinder can act much more quickly. If you were using a cylinder as a pusher or punch for the ball, you could use a quick exhaust on the rod side of the cylinder. That way, when you pressurize the retract (rod side) port, the cylinder would retract, and when you pressurize the extend side, the cylinder would extend, but you would not have to force the air from the rod side all the way back through the tubing to the control valve, instead it could exhaust right there at the cylinder.

Edit: here is a good example.
