Any diaphragm/piston valve that is 1" or over should work just fine.

Most are just kids.Ghetto is the look to go for here, however, there are some treasures hidden out here...

talking about treasure, I'd like your opinion on this: http://www.spudfiles.com/forums/viewtopic.php?t=6725&

Call it a stupid question, but if the gun is supposed to be automatic why do you use a sprinkler valve?It would seem that the sprinkler valve is just restricting airflow. Wouldn't a ball valve have been a better choice.Since the gun runs like a cloud BB gun, I would think that a maximized airflow would increase velocity and cycling rate.

I'm also thinking of making one of these, but a small one to shoot marbles/paintballs. How many do you think it would shoot if it had, lets say a foot and a half of 3" PVC as the chamber and a 1" modified sprinkler? I'll build it, definitely, and maybe make the barrel detachable, so I can try different mag lengths.

No.
A ball valve, could work for these purposes, but it all happens so quickly a ball valve wouldn't open quick enough.
