if u wanna moddify a sprinkler valve with a push button like Joel Surprise, see this.

because I saw a post in spudtech forum about push button valves

edit, may or may not work

dont know how well it would work because the schrader valve doesnt have such good flow, but its worth trying

you are right. how about this?

edit. maybe use a class 2 lever to operate.

ive tried the bike valve thing i had valve extenders which are made of plastic not metal like the valves so you can cut them down so its just the pin sticking up.
it worked ok but not quite as good as a proper blow gun valve
