I want to build a pneumatic version, but still looking around for the right parts. The most problematic being the valve. I have a water rocket installation, which works well and is fun but the pumping to 140 PSI gets very tiring after a couple launches. Gonna get a CO2 bottle as a pressure source soon. A 5kg bottle will get you a lot of pressurised CO2.

For you folks who have made pneumatic versions, did you use a sprinkler valve or something else? I'm thinking a large butterfly valve should do the trick as well. Anyone have any experience with mechanical valves like a butterfly valve? Anyone constructed a homemade diaphragm valve?

I was also wondering how this huge valve works... any ideas?
