need some help with Coaxial vent with sprinkler valve

[Crna Legija]

which side of a sprinkler valve would go to the gun chamber or barrel side? its a coaxial canon

I believe there should be an arrow that would indicate the direction of water flow. In you case air. It should point away from the launcher.

Way to go man, talk nonsense. I can barely hazard a guess at what you want.

Erm..you have the chamber side holding pressure? Shouldn't that be obvious..
