Valve question

Unread postAuthor: Hatheg-Kla » Thu Mar 02, 2006 1:20 pm

So I'm getting ready to build my first pneumatic and I'm trying to figure out what valve to use. I'm building an over under type (not coax) and was going to use an electronic sprinkler valve but I think all pneumatic is the way to go but I don't know what kind of valve to buy. I read a bunch of the articles and keep seeing these green valves with an air gun hose attached which I'm guessing is used to release air to open the valve? the only brand name I've seen anyone mention was a "goyen quick exhaust valve" (still looking for one). Also people mention modifying sprinkler valves but I haven’t been able to find directions on how to do that (or even what that means). So if someone could point me in the right direction I would appreciate it.

Thanks

Quick exhaust valves are different than sprinkler valves. They open faster (that's why they are called quick exhaust valves). But they also cost a lot more and are harder to find (they usually have to be bought online).[/i]

Nope. That is just a piston valve. Quick Exhuast Valves are manufactured by companies such as Goyen.
