X-Valve an co2 questions, just trying to gain a better understanding

[LK-13]

As an aside, one of the issues with CO2 in fast-recharge guns are points where pressure drops rapidly. You actually can't run CO2 on an X-Valve Automag because the pressure drop when filling the dump-chamber is so great (slam recharge) that warm, gaseous CO2 will instantly liquefy.

I'm theorizing, entirely without data, some electro-pneumatic markers may have valves that recharge fast enough to liquefy CO2, similar to the X-Valve.

now this is interesting, this is some information i have been looking for, for a very long time.

so this issue with the X-valve and co2 is the recharge rate?????????

is the recharge rate dependent on the rate of fire or is it constant?
if you shoot 1 ball every 10 seconds will that have the same recharge rate as 1 ball every 2 seconds; or every 50 seconds?

does the recharge rate change with pressure?
does the dump chamber recharge faster as pressure increases?
logic would suggest this, but is this the case?
if you supply the X-Valve with 1100psi co2 will it recharge faster/slower/same if the supply pressure were set to 700psi ?

will the X-Valve operate at pressures lower than 700psi?

What is the lowest pressure the X-Valve is designed to operate at?

700+psi is the pressure where co2 gas can become co2 liquid nominally speaking.
if you can keep the pressure below 700psi co2 can not condense into liquid, or worse solid.

additionally,
the larger the volume of co2 in any given vessel increases it's tolerance for temperature change.
I have a 5 lbs bottle (that's 80 oz that's right 80 oz! ) and because the temperature change is spread through more matter (liquid co2) it can shoot more paint nonstop with lower temperature change than a 20 oz bottle will. the 20 oz not having as much liquid co2 to adsorb the temperature change.

I am running off to work, but Tuna says that CO2 will destroy some red loc-tite seal, or something or other, in your x-valve, destroying your x-valve.

Here is a graph that shows the recharge time of an RT valve at 600 psi input.
Note how long the recharge takes.

The recharge rate is how fast the air/CO2 moves from the input to the chamber. It is always constant and is unaffected by the rate of fire because the max rate of fire is the minimum time it takes to recharge. Any rate of fire less than max, the extra time between shots is done with the chamber already fully charged. With the chamber operating pressure being constant, the rate of recharge is affected by the input pressure. The restriction in the small ports and in the regulator has less of an effect when a higher pressure is applied to the input. Thus, it will recharge faster as the input pressure increases.

Asking whether the X-valve will operate at 700psi is a qualitative question. It will, but not necessarily under all conditions. If you run a level 7 bolt, the chamber pressure will be at about 350psi, and the X valve will operate quite well down to 600 psi. With a level 10 bolt and the longest gray spring, the chamber pressure could be 550 psi or more and the X valve may not operate effectively at 700 psi and may require a full 800 psi or more.
