: Just traded in one of my bulk co2 tanks for a nitogen tank. The counter jockey at the welding shop didn't really want to help me out much with finding a reg for the tank. What sort of regs are being used on the nitro tanks? I know the delivery pressure should be 3000 or 4500 depending on the tank being filled, not sure what the unregulated output psi on the bulk tanks is, but the source psi on the reg would have to handle it. Anyways, I was just wondering what setups other people have for filling from nitro tanks. I've never used an actual nitro tank as a source. I've seen them used, 6000k bulktanks, but what you have to use will have to do with how you plan on getting it filled, to what pressure, and what kind of fill station (from bulk to bottle) you use. If the tank is rated high enough you can get any equally highly rated valve. It's gonna depend on your limits. Scuba tanks are easy because they are 3000psi tops (3500...but) and they're unregulated. You don't regulate the fill, you fill until the bottle pressure is equalized. If you had a 6000psi source, you'd have to watch your bottle's gauge to see when it came to it's full load and stop. Going much over the rated psi would pop the burst disk before any danger. Since the counter boy obviously wasn't going to be of any assistence, I suggest you speak to the manager or owner to get the real deal on what valve you will need and the fittings. I've found that welding guys are very wary about fast filling small bottles, so they may not be as saavy to PB needs and limits. You don't really need a regulated valve for 3000psi filling, I don't know if you do for higher capacities. Hope that helps a little.
