I'm pretty sure you need two regulators to get HPA low enough for PVC...

I think you can get one on google they usually take the pressure down from 800 to 800-0 on a ajustable regulator I think you can get one here:

edit: you need a tank with a preset pressure for this and I'm not sure if it works with co2 and air, air or just co2.

What about an argon regulator for welding? They can take a lot of pressure.

After a bit more tooling around on lowes.com I found this:

would this work with an hpa tank that has been regulated down to 850 psi [co2 pressures]


or this one [but i would have to find some way to attach it to the co2 tank]

That looks like it would wor considering the pressure but I don't know what is the psi output on the tank? If it is above the limit don't use it obviously, just adjust it to the right pressure. And you might need an adaptor for the threads for it to work.

Work sorry, in that last post I was talking about the argon regulator.

Don't need to post again to correct the last one, use the Edit button.

JSR uses a standard paintball reg that reggs down to 450 psi... from that point you can either reg down to 125 or follow JSR's advice and use a QEV + metal chamber

As above, I use Ninja paintball tanks - very good value for money off eBay- (I have two, 13 and 48 cubic inches) that have regs that can be adjusted for outputs of 450, 650 and 850 psi. You have to unscrew the reg and add/remove shims to the spring, so the adjustment is "permanent" during use, but if you're only going to use it at a fixed pressure anyway this shouldn't be an issue.

You can feed your tank directly into a quick exhaust valve (doesn't need to be big, even a 1/4" like this will probably do - you're injecting high pressure into a long barrel to fire a light projectile for the purposes of wargaming, so overkill is not what you're aiming for - and this valve can be piloted with a blowgun or ball valve. You can either plug the pilot valve directly into the QEV and trigger it with a rod from the grip, or fit the valve in the grip itself and connect an air line to the valve, though this option is less efficient as it increases the pilot volume.

Just for a little clearing up, it's entirely possible to reg 4500 psi straight down to 2 psi if you want. It entirely depends on the regulator you're using. As JSR was saying, there are many types of regs made for paintball. Many of them are easily adjustable simply by turning a knob and can be adjusted on the fly. The setup I've been using lately is a 65ci/4500 psi tank and with this regulator I can get output pressures pretty much all the way down to 0 psi. All that's needed to adjust it is turning the knob on the end. This reg is a Smart Parts Max-flo, one of the two easily adjustable inline versions they made. Smart Parts unfortunately went out of business like 6 months ago so replacement parts on their equipment has been a little harder to find. There are several version in their Max-flo series, most of which are adjustable.






This is the vertical Max-flo model, also easily adjustable and I've used it to output similar pressure ranges (~0-800 psi)
