Chad ...I agree with Mario.
The Burkert should be able to flow 46 litres or 12 gallons per sec @ 750 psi with a pressure drop of 5 psi according to the PACulator.

Cv of valve 2
Inlet pressure 750 psi
Specific Gravity of CO2= 1.52 ( Thats Density in the programme.)


Note :- Your ram has a capacity of 1/3 litre ....do the math to get a fill time.

You seem to be making the classic mistake of putting a big valve on a small supply.
The internal passageways of your paintball valve are less than 1/16 and if memory serves me right closer to 1/32 and restricted by direction changes.

If you replaced your bath taps with fire hydrants would you be able to fill your bath in seconds?
NO ... it would take much the same time as before.

So use a buffer tank ( a buffer tank contains a readily available and unrestricted head of gas )
I.E. A suitably rated pressure vessel with an outlet bore the same size as your valves inlet bore and enough capacity to suit ... A capacity / volume of 2 or 3 times your rams volume as a rough guide
