800 psi. But it varies with temperature. If you want to use co2 for a cannon then you need a regulator.

It is 800 for a CO2 tank but check you are not using a HPA tank as they can be 4500 psi. You need a palmer reg.

that helped but where could i find a regulator that can handle that much pressure? i looked at ones today and none of them could handle 800 psi they could only handle like 150 psi . could you point me in the right direction?

Buy a paintball regulator.

You need to do a lot more research before you try to build a co2 system.

I'm not trying to be an asshole. I just don't want to see you get killed because you don't know what you are dealing with.

ya srry bout that last post....... i am just really tired thats all.... i will have 2 sprinkler valves, i will have at least 5 feetof 1/2 inch pvc piping that can withstand up to 250psi and i will be using this regulator:

Ummm. you are goung to have 1/2 inch chambers? FYI they don't make 1/2" sprinkler valves. And sprinklervalves can take a max of 200 psi if you get the super expensive brass ones.

Spudstuff, are you suggesting to use a (homemade) piston valve instead ?

co2 canisters on AVERAGE will output 800 psi depending on temperature, pressures can spike as high as 1150psi though. The comment on hpa being 4500 psi is in the tank, all HPA systems have an ontank regulation system, 90% of them have either a red (800 to 850psi) or blue (450psi) but some such as my evil scion system have an adjustable regulator outputting from 80psi to 650psi. When buying paintball regulators pay very close attention to specs, MOST regulators do not behave well with CO2, unless it is antisyphoned (no liquid, gas state only) liquid co2 freezes up orings inside the regulator causing pressure inconsistency and failure.

Master chief is right

under normal conditions Co2 is like 800 psi but it spikes depending on the weather.

i know your not trying to go expensive. but those regulators are like $80
and it would be more consitent psi from a compressed air tank those run anywhere from 3000-7500 psi though and you would need a good regulators to run it

you also have some co2 tanks with on off valvles you can use those to cut your airflow
