My concern is with using a throttling valve to reduce the pressure of
the CO2 in the cylinder to keep from rupturing the low pressure
needle valve. That is very dangerous. A valve will not reliably
reduce the pressure downstream of it, since the pressure reduction is
a function of flow rate through the valve. If the flow from the
needle valve is interrupted for any reason the pressure on the needle
valve would rapidly increase to full cylinder pressure. This system
would be safe if a relief valve were used to protect it from cylinder
pressure.
Yea, very true.
I totally need to beef up the disclaimer in the article. Risks I'm
willing to take are shark food for the lawyers.
I did consider getting a regulator for it, but the paintball varieties
cost alot ($70+) and only drop the pressure by half. I'd probably end
up needing more than one to get it down to a "safe" level. And that
would have defeated the whole point of the project. But I definately
need to add that information to the article for those who might not be
aware. I never thought of a relief valve though. How cheep are they?
where could I find one that met my purposes? and more importantly,
budget? I don't think I saw one on any of the paintball supply
sites... but I'll take another look.
thanks alot for the input.
