*WHY* only HPA for XValve/Retro??

[DarrylHadfield]

My apologies if this was answered elsewhere; I hunted high and low and can't find an explanation - just reiteration of the same.

Is the restriction of only HPA for the Xvalve or retro only because the liquid can gunk up the internals?

And, for that matter, could one not simply put an expansion chamber into the mix to allow the CO2 to expand, thus allowing only gas into the valve?

Would this negate the benefits that the x/retro valve offer, i.e. would it inhibit or otherwise restrict the responsiveness of the valve?

Thanks for all help.. I'm days away from receiving my first 'mag, and I'm already contemplating bumping from the stock valve to the xvalve!

Even if CO2 goes into valve as air... it can turn back into liquid in the reg and freeze stuff.

Also.. Co2 doesn't evaporate or expand at the same rate every time. So, you'd get velocity fluctuations due to its characterstics.

With HPA... it's HPA, never turns to a liquid and is consistent as far as expansion goes.

Really thats here nor there.. AGD says DO NOT USE CO2... so.. don't use CO2

Good 'nuff for me!

Thanks for the help guys.
