I've had this X-Valve for a number of years, never really got it working quite right. I had another working valve, so I didn't really put that much effort into it until recently. At first, I assumed the problem was the LvL X, because of the constant leaking down the barrel regardless of the carrier size. I replaced the carrier O-ring I was using, and that fixed the problem. I was then able to get the largest carrier size without leaking, easy enough.
Where it gets interesting is here: I threw in the generic 2 shims, test fired a couple of shots, and the marker would have what seems like bolt stick and chuffing (like its bouncing and sticking off a paintball). The problem is especially bad the second I increase my ROF above 1 rnd / 3 seconds My first shot is always good, and seems alright. The trigger doesn't have that smooth, snappy feel that my other xvalve has. It's hard to explain, it just feels slightly off.
-So i threw I installed 3 shims, it made absolutely no difference.
-I adjusted the velocity. No difference.
-I tore the ENTIRE valve down, regulator and all. I oiled EVERY O-ring, and cleaned out and re-greased the regulator. Put it back together, test fired, it made no difference.
-Tried different carriers, and different numbers of shims, it made no difference. The only interesting thing occured when I installed the tightest carrier. When I would fire and then hold the trigger, it would slightly leak down the barrel. Normally the leaks seal up after holding the trigger.....hmmm
-Switched the valve from the RT rail to the Dallara rail, it made no difference. The sears that I'm using have recently been used on other valves and with no problem, so I don't think it's that.
- I've used two 850psi tanks, thinking maybe one of the tank regs was off, but that did not fix the problem.
What the heck am I missing?! I'm just completely lost here and don't know what else to cover. Ideas? :spit_take :cry:
