    RT valves w/ co2

    I just traded for a classic RT and just getting back into paintball i don't have HP tanks. I searched the forum and from what i understand, correct me if i'm wrong. C02 on a RT valve wont' hurt anything but bc of the re-charge rate of the valve it may just(well probally will) freeze the o-rings. causing leaking/shootdown all that stuff

    does this seem correct?

    i'll probally trade a cocker i have for a nitro tank here soon but just wanted to ask in case i get the ich to go try out this RT with some co2.

    thanks in advance

      Yes, it'll freeze the o-rings, no matter how much you antisiphon and regulate it. It will still condense back into a liquid in the valve.

          RT's suck on CO2. Really, they shoot like crap. If you take an RT on the field with CO2, you will be walking off the field before the first game ends.

          Not likely to be by elimination either

              as long as you shoot in short burst you can do it ... make sure you oil the gun well ... i've seen it done personally ...

              there's a chart here that will help you out ... http://paintballpalmer.com/showthread.php?t=30

              How the co2 will "condense back into a liquid in the valve" ?... I'm assuming that you are talking about the reg and not the on/off. I don't understand how this will happen unless there is a severe pressure drop when the co2 gets to the reg. Is there a pressure drop at the reg?

                  There is a pressure drop at the regulator and because of the way the retro valve is designed, it amplifies the negative effects of CO2 condensation. You can get away with using CO2 if you add a good regulator (one that can handle CO2) in between the bottle and the valve to reduce the pressure differential. This will reduce the recharge rate but you won't have the condensation problem to the same extent if at all.
                  Except for the Automag in front, its usually the man behind the equipment that counts.

                      I really want to know this info cause my wife got me a ReTrovalve for christmas (she thinks I don't know but the owner of the local pb shop asked me how I liked the valve last week... she didn't tell him it was a suprise)

                      back on track ... I only have c02 tanks and probably won't get one till feburary after i file taxes... so and explanation like "the co2 enters at this point... goes into here ... and thru here and this thing causes the pressure drop because ... and the pressure drops from XXpsi to XXpsi ...

                      I know that the pressure drops after the regulator to (i think around) 300 psi ... is this where the condensation/liquidation takes place ... in the chamber between the reg and the on off??

                      that will help me understand on how to work with what I got ...

                          i don't plan on playing a game with it until i get a nitro tank, i just wanted to make sure if i go out and do a few test shots or whatever that the only thing it would hurt would be the o-rings

                          i thank you guys helpfull as always =]

                              It usually won't even hurt the orings. If they freeze, the CO2 will just push past them and you will experience leaking and the valve won't function properly.

                              turbo chicken: The front chamber of the mag ( after the on-off) runs at about 350psi for a level 7 and could be more than 500psi in a level 10 equipped valve. The level 10 lowers the differential between the input and operating pressure so it would actually be better on CO2 than a level 7 equipped retro valve.

                                  i remember reading on the palmer board that if co2 is over 600psi it stays a gas ... i see what you guys are talking about ...

                                      The pressure gradient in the RT is much sharper before and after the reg than a conventional marker.

                                      That means the co2 expands much faster, and so cools much faster, with less time to pass the heat on to it's surroundings. Thusly, it will condense under all but very slow rates of fire, causing the marker's velocity to spike.



                                      You can do it, but it can spike to potentially dangerus velocities.

                                          The CO2 gas pressure is around 800psi depending on the temperature. The lower the temperature, the lower the pressure at which it turns to liquid.
