Are you asking if it will work? If so, yes. You only need enough flow rate to keep a constant pressure difference between both sides of the diaphragm, just don't leave too much space on the fill/trigger end of the diaphragm since there's only so much cfm the little solenoids can release per second (ideally you want to just dump all the air on that one side so that the air in the "firing" side can just dump out).

Also, I'd go with the diapgragm/piston valve. Using a sprinkler solenoid limits you to the max cfm rating and psi rating of the sprinkler solenoid (which for some is a good thing, because it's better to pop the spinkler solenoid's diaphragm than the PVC pipe). Ball valve, well, you just have to be quick with turning a knob.

Hope this helps.
