is it possible to pnuematically mod one of these?

I don't see why not, replacing the solenoid with a blowgun as on the "normally" configured valves.

[c11man]

its possible but the anti syphon part of it is extremly restricting in flow and the main vavle is even no as good

[covey12]

so possible, but impractical

Correct. These have been modified for a compact over/under, but the performance leaves a little to be desired.

[Brian the brain]

So yes, but it is related to a well known snake...




These valves are referred to in Latin as

"Floa Constrictor"

[Hubb]

The Sprinkler Valve covers this, as well as a few modification techniques for an anti-siphon sprinkler valve.

As has been mentioned, for performance, just get an inline and a couple of elbows. The only true reason to use this type of valve is to make that bend without the elbows.
