Can this design be scaled up to 4 inches?

@TheLPsyche Absolutely! Better scale the bumper up by 20x!

@techwizzy I'm in the process of building an air cannon with a 6in. diameter barrel for a physics project and I wanted to incorporate this valve into my team's design as to make the most of our air pressure. I'll post a video response when it's done (deadline is Novemer 12th.)
