well...technically... McMaster put two contradictory informations on the same page... so don't blame me.. so to put it short McMaster f***** it up

people who are seriously involed in pneumatics acctually use those diagrahms... the fact that they put it the other way round is exactly as if they wrote it's a NO valve but put it in the right way in the diagrahm

EDIT
I've found something on it on exactly the same page
National Fluid Power Association (NFPA) Diagrams— Found on most air control valves, these diagrams depict air flow and valve action. They're useful for replacing control valves—match the diagram on your valve to the new valve.
so you see... someone might have already ordered or will order a wrong valve becasue of this mistake

that was just to clear things up

My three-way ball valve finally came in. From my quick look at it, it seems nearly perfect aside from the price. Turning the valve is easy. I should be able to hook a small pulley to the valve without difficulty too. With a small pulley attached to the valve I can use a cable to actuate the valve, allowing me to put the trigger nearly anywhere I want to.

I should be finishing up this gun in the next week given that I get my paycheck for the gas station. This one should be pretty nice. It won't be semi-auto, but it will have a high rate-of-fire, and it will be fairly powerful.
