I have used this setup for 2 years running and mine is more primative than that, though the only thing i'm upgrading is the co2 cannister from a 20oz to a 5lbs one.
need to show a picture, let me see what you have, I want to know it is a a flow control valve or a true pressure regulator attached, to your paintball tank.
Jaggedfury's paintball co2 setup is not a pressure regulated valve but a flow control valve, a solenoid can not be attached or something will burst.
People PM me all the time want to attach a solenoid to the flow control valve design, my answer is "NO", unless it is true pressure regulator. There was a member bugging me with many pms, want a postbody kit to attach to the ASA valve!!!!, explain many times and eventually send him a high pressure, high precision swagelok metering valve so he can attach this valve to his ASA on/off valve, hopefully he likes the nice metering valve, but a timer via solenoid control is not possible.
here is some pictures of my personal paintball setup, it is the true pressurized regulator attached, so a solenoid control is possible.
IT IS NOT JAGGEDFURY's FLOW CONTROL VALVE DESIGN, don't be mistaken.
