I'm Looking for a valve that Is capable of withstanding the pressure of co2 from say a 20oz paintball tank. This in not for a nerf gun don't worry. Although, I was wondering If I could use the solenoids I see everyone using on there homemade guns or they wont stand up to the pressure? I need an electronically controlled valve that is capable of hooking up a push button for on/off opperation.

Thanks guys!

I don't quite understand. What do you need a solenoid valve for?

Edit: I found this:

"Regulator – The output of either the Nitrogen or CO2 tanks is about 800psi. Solenoid valves and actuators can only safely operate at about 100psi. The regulator decreases pressure in the airlines to levels that you specify (by turning a screw). Regulators are standard paintball parts, just like the expansion chamber and the tank. You have to be careful about which regulator you order. Not all paintball regulators can decrease the pressure below 100psi. Look for regulators that say they have an adjustable output pressure of 0-500psi."

Found Here.

All I need the valve for is just to regualte the flow of co2. Yes indeed, co2 tanks have an output pressure of around 800psi, but I need that high pressure. I can't run it through a regualtor first to lower the pressure down to say 100psi. So the lawnsprinkler solenoid valves only have a max psi rating of around 125tops...not good. Does anyone know of any other type of solenoid with a psi ratting of around 850psi?

McMaster-Carr has solenoid valves that will work, but they are probably out of your price range, as they are around $500-600. A solenoid valve that can operate at this type of psi won't be something you can pick up cheap at your local hardware store. You could possibly tear apart a cheap paintball gun, but as far as I know they have a very limited range.

I could use a Nitrous Solenoid (This idea is to create a co2 purging system for effect.) I'm trying to save money with the solenoid and look at all options. If I can't find anything thats safe (and under 150$) then I think I Will just go with the kit.

Get a QEV, it will hold enough pressure

The cheaper solution that would require some machining is to simply link a lever-arm ball valve to a servo to make your own solenoid controlled valve. Or use a push-button valve and a solenoid (this option will give you a much wider variety of voltages to choose from).

Could you explain a little more on the push button valve and the Solenoid, sounds preaty cool?

you wire three 9V DC batteries in series, so you get 27 volts. You the use a momentary on switch to activate the solenoid, and when the switch is released, it shuts off, returning to normal.
