My computor didnt like the adobe file, so I couldnt check if there were any prices on there. How much are they? I mean if they are reasonably priced then hell get me one, but odds are they are gonna be pricey, like anything else worth having. Sigh

DANG....those are big diaphragm valves
. Although needless to say 6" is overkill for a TB launcher, 3" should suffice. And it's pretty much the same design as a rainbird so you could easily mod it.

Hmm. I think we need one order of an 8" porting barrel sealer, built to take 300 psi - and then we'll see about the ultimate valve...
On a serious note, nice find, but I'm not sure they'll be accessible to most people.

To vent an 8" piston valve, I'll need to find a 1.5" QEV...
But, sensibly, it looks like many of the valves in that link are remotely activated, in a fashion not too distant to using a blowgun on a regular sprinkler valve.
