Hi
I've made a very powerful pneumatic gun based on a piston valve. It looks ugly but it's a prototype yet, because i don't have enough money and needed tools now to finish it. But it still shoots. Tested with paintballs and 15mm steel balls(barrels are exchangeable). I've been able to launch the paintball at 1175 fps at 120 bar and almost crash through the 25mm thick wooden board. 15mm steel balls measured at 1050 fps at 150 bar.
Chamber – stainless steel pipe. Volume is something around 115cm³.

Great work! Is it a spring ball valve that pilots the piston? To be honest with this kind of setup you can achieve practically the same performance using the ball valve as the main valve directly...
