Mixed gas
Re: Mixed gas
Does a CO2 regulator not need a pressure release valve because its bottled at much lower pressure than the mixed gas?
Re: Mixed gas
Not really because increasing the pressure will cause more CO2 to condense into a liquid resulting in the pressure not changing at all.
I've copied this from where I wrote it on another forum. May help?

Re: Mixed gas
Small correction: "Should have".
Many of my Corny kegs never had them fitted (blank lid) and some others have the PVR port welded over. Not a comfortable situation! I have to make provision for a PRV in my supply lines. But for me the hazard is mitigated by only ever using, and priming for, very low pressures. But some yeasts (S-33 I find notorious) give all the appearances of stopping at high FG (1.020-1.022) but have actually just slowed down a lot. I had one keg maturing for several months (i.e not connected to the gas lines and the PVRs attached to them) get up to 80-100PSI.
(EDIT: This is answering from the "downstream" perspective, I assumed the earlier question by "Alexdc12" was about "upstream" of the regulator - i.e. the gas cylinder - and I don't think I answered that right...
If a CO2 regulator was attached to the much higher pressured mixed-gas cylinder would not a PRV on the CO2 regulator trigger? Possibly. But I'm not convinced all the regulators are different be they for CO2 or mixed-gas, only the coupling changes (male to female), so the PRV on a CO2 regulator will hold over 3000PSI which it might see in a mixed-gas bottle - and then again it might not as it should see no more than about 900PSI (CO2 cylinder). A guess: As the high pressure gauges on a CO2 regulator nearly always read upwards of 3000PSI yet will never record a third of that.
