Hi. I'm not completely familiar with some of valves you have here. I'm interested mainly in anything that releases instantly with as little obstruction for air passing through as possible. I am building an air gun, and slow releasing butterfly valves no longer cut it. Please enlighten me if you can on exactly how these valves work, are the electrically driven? What kind of pressures can they handle? Quick releasing? Standard plumbing style fittings?

Thanks.
