I HATE BALL VALVES!!! Sorry, please use something better, on my current gun, I took the valve off of an old air duster, it works great!

really? i love ball valves they are CHEAP and durable plus if you have any muscle at all can open VERY quickly. not as fast as a sprinkler valve but wtv

ug, sorry, but they are 2 bulky, ugly, and they are hard to open. They also suck as triggers. I confess, i did use a ballvalve on my first gun, but i only use airdusters and sprinkler valves now >.<
