What do in need, and where can I find it?

I had paintball CO2 a while back and I eventually got tired of having to refill my tank every two weeks. I would like to try it again but I want to be able to turn it off automatically when the lights turn off. I have an electronic switch but the 800psi pressure is too much from the tank. Any ideas? This is what I have...

You will need a solenoid in order to turn on/off your CO2 automatically.

However, most solenoids can only handle a certain pressure, so you will need an actual gas regulator to step down the cylinder pressure from 800 (or so) PSI to within the range that the solenoid can handle.
