Pneumatic Dump Valve for T-Shirt Launcher

[Josh Adkins]

Our team also used a sprinkler valve, but we hooked it up to a relay instead of a solenoid.

If I understand correctly you used the solenoid already attached to the sprinkler valve rather than modifying it?

I think the only difference between the two methods is the time it takes to release the valve. I've read the modified sprinkler valve releases up to 10x faster, but I've never actually tested one without modifying it.

You could always test the sprinler valve out of the box, and, if your not getting the results you want, go ahead and modify it.
