I disagree a ball valve has great flow if you can cet the thing open quick enough, there great for higher pressure and have great power with a detent to hold it back till say, 500 PSI which a sprinkler valve cant handle

*sigh* I italisized the "almost" part for a reason
and you stole that from JSR

Yes, bust it not thievery, you say piston valves are the best all the time, you "stole" that from a ton of people, plus I designed a gun to test that concept but I havent built the shock pump yet

Nope, never said piston valves are the best. Burst disks are, and you can quote me on that. Or perhaps its the valveless launcher... IDK.

No you told a guy the best valve to build it a Piston valve, but technically a valveless launcher doesnt have a valve

Find the post man, find the post.

Hence the name

but we were discussing valves, and Ill find the post eventually I dont feel like going through 1305 post, it would take a while

In a way, the detent in the valveless launcher acts as the valve. It is what holds back the air pressure. But then again, the projectile could even be considered the valve too, because it does the same.

that depends JSRs prototype use the pellets deforming shirt to hold the air and a screw as the trigger to hold the pellet

Umm.... deforming shirt?

my bad typo, I meant skirt

"Gun Freak".....tell you a ball valve is the least powerful pneumatic valve to use. They have poor opening times unless you build a trigger system and spring load it which I think is a pain.

You state that as fact but, my guess is that you have little or no personal experience to justify such an opinion. You probably read it somewhere and rely on it as fact.

You screwed up that quote
Most ball valve cannons aren't spring loaded, therefor have terrible opening times, and although they have good flow, they can easily be outdone by the other valves I suggested. I have nothing against ball valves. In combo with an air cylinder or trigger system, they can rival a piston valve in performace.

@ gunfreak and clemson...you guys ever heard of CHAT or PM?

But a qev and a piston valve would be able to handle that, and they would open much faster.
