Minimum PSI To Operate X-Valve?

[Vex]

Is there a minimum pressure that needs to be in my HPA tank in order for my X-valve to work? I ask because it doesn't want to gas up if the tank has under 1500psi in it. I recently purchased a used Flatline 68/3k and can't get my gun to gas up. I've got about 825psi going into the valve from the Flatline (yes, the Flatline works...)

Should I just fill my tank to the max and tweak my valve from there?

Once the tank dips below 500-600psi generally, the valve won't recharge. All valves are different though. Mine stops at 400-500psi.

If you mean what input you need, I believe 650psi is the minimum. But that'll give you really bad recharge.

Try turning up the velocity. You've got a level 10, so the internal operating pressure is a bit higher.

as dayspring said, turn up your velocity. also note that air guages can be off by as much as 10% of their face. meaning that a 1200 pis gauge can be off by 120psi, or a 5000psi gauge can be off by as much as 500psi

Thanks for the info--I had no idea that the pressure gauges could be off by that much (10%)!

The reason is because the guages are micro-guages. It's hard to make those accurate because they read by 200 psi per mark.

my mag was running abotu 650 psi at 2500 psi on the tank....after that the mag woudl just put to a stop acting like a tottal peice of crap....i tried my friends 800 output adn my mag ripped liek 15 bps....my tank shoudl be back in a week from centerflag with a new output at 900-1000 my mag should be happy now
