So i was trying to build something cheap to use a paintball tank to pump c02 into my keg. I put something toghether that would just release the CO2 using a valve instead of a regulater. It did have a PSI gauge on it before the valve. I asked the guy at the homebrew store why i couldn't just do that. He told me a valve would not work because it is not sensitive enough let out just a little bit of co2 and i would end up with all foam. With that, I scratched the idea but I would still like to know what exaclty a regulator does that a valve would not ? What the heck is going on inside those things.
