Check second hand shops that have tools. Sometimes you can find a welding regulator. I picked up one for about $15. What output pressure do you want? Welding gas regulators are good for 0-35 PSI. Oxygen regulators are good for up to 50 PSI. Argon regulators are good for up to about 150 PSI.

If you look for CO2 beverage regulators, they come in a couple varieties. Some are set for 50 PSI, some 100 PSI, and some adjustable for 0-150 PSI.

The 50 PSI regulator often called a secondary regulator is designed to run off a lower input pressure. They are used in the soft drink industry after the primary 100 PSI regulator. They should not be used on unregulated CO2 bottles, bust should be used on systems providing less than 200 PSI input.

Well, the one that -_- posted a link to isn't even a pressure regulator, it's a flow regulator.

but it regulat the pressure by left the over pressure air out


If you want useful responses, you may want to contact a member who speaks fluent English, work out together exactly what you're trying to say, and then post a version edited by that person. I know English is a very difficult language to learn, but it's difficult to respond to a garbled question.

Now, the useful information I can give you is that most dedicated air regulators are not rated for input pressures higher than 300psi. You'd be looking for either a general purpose regulator, or a welding regulator modified by removing the CGA adapter on the inlet and replacing it with an NPT pipe nipple. Either way, expect to pay $100 or more (unless you find a cheap CO<sub>2</sub> reg to modify).

Also, welding gas regulators are not nearly so restricted in range as Tech assumes. My oxygen regulator, for example, can provide up to 120psi on the output, and they are available up to (and possibly over) 200psi output pressure. My nitrogen regulator was of the same style, and rated for up to 500psi output pressure.
I do, however, second his suggestion on checking second hand shops. You may get lucky, and find one that only has a broken gauge or some other easily repaired issue.

I have a regulator that works for 150 but when i try to reduce the pressure the air begin to leak from the regulator. The leak only stops when comes close the pressure i have set :(I'm try to regulator 400psi to 100psi

That's not a problem, that's a feature. It's called a self-relieving regulator. You can either plug the vent, or buy a non-relieving variety.

It sounds like you may have hooked up the regulator backwards. Try switching the input and output.

The reg on my air compressor is relieving, and if I want 50 PSI out, it'll bleed the downstream portion till it's at 50, but won't bleed the 6 gallon tank to 50.

@ ramses. i think DYI is correct. its most likely a feature of the regulator.

and i would definetly look at surplus and used tool places. i was able to pick up a new 3/8inch 400psi regulator that has a 0-200psi outlet for only $15. this regulator is very handy as i can use my propane tank (350psi) for lower presssure PVC cannons. i

the same place i got my co2 tank, 600psi gauge, cheap fire extinguishers, 1inch qev, a couple pneumatic cylinders, assorted dirt cheep high quality brass fittings, and some ball valves
