Can anyone give me the valve stats for a 3/4" modded sprinkler valve that I could use for GGDT?

hubb017, those are stats for a 1" sprinkler.
This question has come up before... last time, at least, we didn't have actual values.
So I guessed; I scaled everything by the ratio of the pipe diameters.

If that's good enough for you, you can do that (or look up that thread and save yourself some work.)
Otherwise... pull out the calipers and start measuring stuff. We'd appreciate the numbers.

Eh, thats the problem. I don't exactly have one I can pull out atm. I was trying to decide what kind of valve to use, and I haven't built any larger pnumatics b4 due to the fact I live in the city so... I mean, I would have, but I don't have the capability. Which is why I am asking.
