Co2 regulator help?

If I used this regulator body in a build, would it be able to run atomic co2 diffusers? I thought I read somewhere that the max working pressure is roughly half of the low pressure gauge. If that is the case, for this specific regulator, 30 psi would be the max working pressure (60/2). I am currently using an atomic diffuser and I tend to see the best results around 42 psi. If anyone could provide some insight that would be fantastic.

Unless this is a fixed pressure regulator I don't see how this would be any true. The gauge is just that, indicating the "out" pressure, it is not limiting the pressure. You can easily blow out these gauges if you are not careful when connecting the reg to the tank. Pretty sure you could max it out if you wanted to.

Perhaps someone with more experience with different regulators can confirm (or debunk).

Yeah it will work. I run mine almost at 50 psi for my inline diffuser.

With the that same cornelius body?

I found out I read that information on OldPunks's Co2 build thread. "Generally, you want a regulator that has a working pressure between 30-100psi. In most cases the low pressure gauge will read 60-200psi. The low pressure gauge will usually read double the the max working pressure." If someone who is really knowledgeable about regulators could jump in and explain why the working pressure would be 1/2 the low pressure gauge that would be killer.

Yup. You will just need to add solenoid, needle velve and bubble counter.

My working pressure gauge reads from 0-60 I think and I run it almost at 50. Probably some of the more experience folks here could answer your question.

work, built about 10 of these already, but they are single stage.
Your Cornelius regulator is ok to go with the atomizer diffuser, because it has no problem to adjust to 40psi. An atomizer diffuser require 30psi to push through and 25psi back pressure when operating.

If you are building yourself a pressurized system, get the double stage regulator and make yourself something much better.
Darkblade and oldpunks both have informative threads to help you to build one, and the links in my signature cover some more detail on such topic.

In general, the low pressure gauge is chosen such that the maximum delivery pressure can be measured via the low pressure gauge.

For example, if your maximum delivery pressure is 200 PSI, but your gauge only goes from 0 - 100 PSI, it is quite meaningless.

This is why if you (say) have a 0 - 100 PSI gauge, the maximum delivery pressure should fall somewhere in between that range.

That being said, ideally, you would take a look at the manufacturer's specification sheet to determine the maximum delivery pressure.

I already have a so-so single stage regulator, but was thinking of building my own for the experience. Do you think it is worth the additional cost to build a double stage regulator rather than a single stage regulator with quality components (needle valve, solenoid, etc)?

Just the learning experience alone is worth it

Any experience gained for minimal cost is definitely worth it!! I would use the best quality componenets you can, I am learning the hard way about using economy equipment
