Large Cannon Valve Ideas

[Solar]

Just wanted to add my 2 cents about my favorite style of valve. This is a positive pressure piston valve. It differs in the way that it doesn't exhaust air to fire. Instead it pressurizes a second piston in a separate cavity to open the main valve piston. No such thing as a misfire caused from a leaky pressure vessel or discharging the vessel.

Speaking of which, have you ever thought about making an animation of how your valve works for people who don't understand?

Doesn't have to be the same configuration as yours, but just the basic concept behind it.
