Very high velocity pneumatic parts.

Post questions and info about pneumatic (compressed gas) powered cannons here. This includes discussion about valves, pipe types, compressors, alternate gas setups, and anything else relevant.

Yup we're very familiar with flexible diaphragm designs.

Sounds like you've got a plan going now.

After you've made your sprinkler valve cannon I would suggest taking a look at piston valves if you're really after speed and power.

If you're not into building them then a piston QEV is a easily installable alternative (see signature cannon) with three threaded ports.

If you're purely interested in performance, I would agree with the triggered burst disk suggestion. It's relatively easy to build if you can source the right parts, might be a slightly greater pain to reload than a conventional valve but for sheer muzzle velocity nothing comes close.

You can find all the details you need to build one here in the wiki ;)
