Some small pilot valves can switch fast enough for paintball use. The problem is their flow rates are generally to low to fire a paintball at a respectable speed. Often the small valve works a larger valve that also serves as the markers bolt and closes the breach before the paint is fired. http://www.zdspb.com/tech/index.html can walk you down just about every reasonable path to putting paint down range. New valve designs and methods come out all the time but generally they are rehashes of old designs with the parts flipped around a bit.

I have not been able to find a lot of info on manufacturers dwell time, but from what I have found that sounds about right. For Y (reload time) I would think adjustable between 0.5 - 5 seconds. For X I have no idea if my valve can switch on and off that fast, trial and error will have to sort that out, along with pressure adjustments. --~--~---------~--~----~------------~-------~--~----~ You are currently subscribed to the "R/C Tank Combat" group.
