How badly did the LPS wreck my Xvalve?

[cadams]

So I went by CO paintball this weekenf and got my HPA filled .. no big deal, like i have 100 times.

I got some new parts for my mag, and new set of o rings. planning to do a little tinkering. So I change all the O rings, reinstall everything, and air up.

when i got the velocity squared away i started playing with my newly found ULT bounce (more on that another day, another thread).

I'm tearing away on this thing and all a sudden ... ??? why is my expansion grip cold? Wha..???!? My HPA tank is cold too ... like it would with CO2 ... but this is an HPA tank. conpressed air gets hot when you fire fast, not cold ... can it be? how could it be? is it even mechanically possible to do?

did the LPS fill my HPA with CO2 by mistake? WTF? If so, you think a free O ring kit should be included with my re-fill? When they purge all the CO2 and the HPA tank freezes (and we know it will), what effect will that have on the integrity of the kevlar? Is The tank ruined too?

Depending on how fast you were firing - a HPA tank will get cold as well. The only thing that will be warm is the X valve.

Your HPA tank gets warm when its filled because as you compress a gas it releases heat (you need to remove heat from gases to compress them). Basic rule of thumb, gases require energy to expand. Where does that energy come from, well form the surrounding environment. The reason CO2 freezes up is because it has to go from a liquid to a gas. Which requires substantially more energy than just an expanding gas. If you'd like to try a little experiment and don't mind wasting some of your HPA. Take the macroline off at the valve and open up your tank (not fully open, its a little noisy and it blows stuff around). let it go for a few seconds. then feel the tank/asa temperature.

thanks guys. the valve didn't seem to get too cold, it didn;t get warm though either. the asa and tank did though. even had some condensation on the asa.

but then again .. i've never shot that fast before. Kinda freaked me out but in retrospect, CO2 would have frozen up way faster. I continued to shoot until the tank was empty and it only got chilly.

sorry for freakin out on you guys, thanks for the help.

Hehe, on my mag I can get the ASA to frost over nicely with a super long string of bouncyness , not uncommon at all, just normal Physics =)

If you're getting reactivity, it's definitely not CO2.

I was emptying my 92/45 on my ego 7, and I shot 15 bps (dry firing) for a full 3 minuets to get the stupid meglo-tank emptied. After it was finally empty, the ego and tank were both FREEZING, and condensation was on both.

Don't worry about it
