1. Most efficient valve available for an autococker. I have one in both of my cockers(my Sandridge and my personal custom one), and they both get unbelieveable efficiency. I shot ~1800 rounds from my custom autococker with a 300 psi fill @ 285 fps.---The reason is that this valve will shoot balls until the pressure reads almost 0 on your gauge. Thats right, almost 0. The valve reduces operating pressure of your gun to around 120 psi or so depending on you spring selection on the hammer. But my guns will shoot paint at 285 fps even though my gauge reads almost zero(granted these gauges are not really precise). The downfall to this is that I noticed that from 3000-2000 psi, you don't get that many shots, and from 2000-1000 psi, you get roughly double the amount of shots, and the last 1000 you get almost half of the maximum amount of shots!! This becomes problematic if you are sharing a scuba tank with someone and toping off after every game. Beacuse you will fill(top-off) more often so that your gauge will read 3000 psi. However, if you drain your bottle to 100-200 psi then you won't have this problem. Some days I find myself bringing along my scuba tank for no reason. But then again I play front, and I don't shoot as much. Those who play back will probably have to top-off only once if you shoot a case-and-a-half and you wait until you've almost drained your bottle before topping-off.
2. Makes the gun more consistent. This valve works by making your cocker's velocity flow dependent. And flow is controlled by you regulator, not you hammer kit. So what you do is back the velocity screw all the way out, and adjust your regulator till it plateaus. Then turn up your velocity screw till it reaches the proper velocity. In this scenario, the gun's velocity is controlled by the regulator and not the hammer. So if you have a high quality and consistent regulator like Palmer's, MacDev Gladiator, Black Ice, or some Vigilante's( NOTICE ANS Gen-X is not one of them) it follows that your velocity will be consistent. I've set up a number of autocockers with velocities of +/- 1 fps with this valve and a good reg.
1. Like I said earlier, those who feel the need to top-off after every game will find that you're draining your scuba fast. You will need to change you tank filling habits.
This valve performs well on any 98 or newer autococker(these have larger valve chambers). Older autocockers will need to have the valve chamber enlarged by a GOOD airsmith to get this valve to work. But it is by far the best valve on the market, and I have tried them all. I really recommend this valve to those players who cna't afford a scuba tank or the means to lug one around, because you can get a fill at your local store, and pretty much play the whole day depending on you much paint you dump. I would give this valve a 10, but I didn't leave the "bad" box empty.
