Re: [APD] paintball CO2 for a mini tank

[Vaughn Hopkins <hoppy1 at surewest_net>]

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.
