CO2 & Comp. Air??

How do you lower the pressure on a CO2 tank Enos?

But when liquid or liquid vapor Co2 goes through a reg into a LP enviorment, it expands instantly raising that pressure. Example: 800psi--reg to 400psi-expand 550psi in lines--valve--spike.

Just like with AutoMags; when liquid or liquid vapor goes through the built-in reg on a Mag, it evaporates very quickly into a much high pressure inside the power tube. This causes high spikes, especialy with a LP operating marker. Iv seen spikes from 289fps-380fps just from pointing my gun down for a few seconds with my Mag.

Im not sure where your going Enos, but this whole concept provokes me with an idea of two regs to the same pressure with a gap or volumizer in between (if thats not what your thinking. The liquid will pass through the first reg into the "LP enviroment" and evaporate into a higher pressure there, then the next reg will take the stable gas back to a lower pressure. Example: 800psi tank--reg to 400psi--550psi after liquid expanding in the volumizer or lines--reg #2 back to 400psi--valve.

I've had excellent results running c02 thru dual regualtors at very low pressure.  140-180 psi. 

I cut the output pressure of the tank with a Palmer to about 600 then thru a coiled remote than a front grip reg to about 140-180.  My theory is that it let's the regs. split the duty.
