Is this a good qev? im going to be using it on my 6mm airgun(in the pneumatic showcase). I like this one because its small, and i like this shape over other qevs.

Much better than a ball valve :)

That's debatable... But I wouldn't care to debate it. :roll: :D

Fine, much better than an unmodded manually operated ball valve :P :D

Also, i unscrewed the propane fill valve, and popped in a scraeder valve, and pumped it up to 125 psi, and fired a nail dart and holy shit was it loud and powerful!

Since you have a small metal chamber, why not invest in a shock pump?

This type is reasonably priced and will happily go to 400 psi, which should give you at least 300% more power ;)

edit: looks like we linked to the same type :)

Lol i just posted a link to the same pump but for 20 bucks with free shipping lol. and would high pressures go well at all with that QEV?

Specs rate it to 140psi but in practice many on this forum have abused larger QEVs to pressures beyond 500 psi, you shouldn't have any worries.

As to a pilot, I've used standard shop blowguns at 400-500 psi without leaks, but a ball valve is simpler and a safer bet.

I have a few of the other style QEV's (the non-boxy kind) in 1/4'' they have been to 450psi with no damage to the valve
