Check the wiki for their operation and Fastenal has them on their website, under the name 'exhaust valves'.

a qev is like a diaphragm or piston/diaphragm valve the one i bought is the piston kind. qevs also increase the power.Chuck wrote:If I knew what a Qev was and how to build one I wouldn't use a sprinkler valve. I had nothing but trouble with them.They want seal and they let air out the barrel.ALIHISGREAT wrote:isn't the sprinkler valve a bit big for a pellet gun, i would use a qev and blowgun trigger, this would also give the gun better lines.Chuck wrote:Well here it is starting to look more and more like a gun now. I decided to make it a pistol. I want to give it to my little Nephews. I want to add a scope and such. Anyone figure out what the air tank is made off LOL.
