Chamber Filled Pilot QEV?

[Jabingo19]

Hey spudfiles, wondering if you guys could help me out.

I need a QEV which works like a sprinkler valve (I think this means it's chamber filled? But I'm not totally sure...)

Basically I need it to act as a sprinkler valve, still blowgun-triggered, I just need it to be smaller than a sprinkler valve to get it to fit in a custom housing I made (before getting the sprinkler valve shipped to me ) and achieving higher pressures than the 125 of the sprinkler valve would be nice as well.

Also, if it could be a 3/4 inch QEV (do these exist?) that would be phenominal as well.

Thanks in advance for any help

Both qev and sprinkler valves can ber chamber fill and via pilot, but to do it with qevs you will need to put a hole 1-2 mm big in the edge of the piston and put a spring behind it.

They do make 3/4" qevs check ebay

Okay awesome thanks Crna. Thing is, if I drill a hope in the piston, won't it slowly leak air out?

Thanks

You don't drill through to the barrel. Drill through to the chamber so it can equilize.

Oh okay gotcha.
