X-Valve won't shoot....

[Temo Vryce]

I'm having troubles with my X-Valve. It just won't shoot. It presently has a lvl-X and ULT in it. What information do you need from me to help me out here? I have tried searching for this problem and I have found very few helpful results.

Well there is not much to work with in you description.

Have you tried turning up the velocity on the back? That could easily be the issue. Next, is your tank holding more then 600psi of pressure? Does ANYTHING happen when you pull the trigger? Any sounds or movement of anykind? What size spring and carrier are you using? Have you tried switching to a shorter spring or larger carrier? Does the sear adjusting rod sit right next to, or close to, the back of the trigger? Is the saftey on? How many shims are in the ULT?

[Temo Vryce]

The tank has about 2000 psi in it maybe a little less. The ULT has 3 shims. The Sear rod is close to the trigger. but doesn't move. I haven't played with the velocity at all. It's got the Red spring in it right now. I don't know what Carrier it has but give me a few minutes to tear it down and I can tell you. I do know that it doesn't have any shims in the power tube.

EDIT

The Carrier in the power tube has 2 bands no dots.

What's your tank's output?

The trigger rod moves, but doesn't fire the marker? If so, my best guesses are that it is either an input pressure problem or too many shims in you ULT.


The trigger rod does not move, like you can't pull the trigger at all? If so, my best guess is your on/off is jammed somehow, maybe the on/off pin is bent? Is your safety off?!?! lol, you have to check everything.

[Temo Vryce]

The pin doesn't appear to be bent. The tank is high output. The safety isn't on as I have put a Classic valve in and it fired just fine. Any other thoughts?

[questionful]

Check your on/off teflon O-ring and the little black O-ring.

[Temo Vryce]

The O-Rings are in great condition. Both the ULT and LVL-X kits are brand new. The X-Valve I believe has seen some use. Please keep the suggestions coming guys.

Turn up your velocity. When you put a longer/harder spring on the bolt, you need to add pressure (velocity) to make the gun fire again.

I did the following once, so don't be insulted when I mention this, but is it possible that the grip screws are too long and are hitting the sear arm, keeping it from moving?

[questionful]

Temo, let me get this straight. You're saying you can't pull the trigger at all? But with a classic valve it works fine? And you never said what your tank's output was, I think that is the problem, so what is it?

[Temo Vryce]

I will try the Velocity thing when I won't wake the wife and kids. I'm also going to oil the snot out of the on/off. As for the Tank's output pressure, I have no idea. I purchased used from another AO member that told me that it was a high pressure output. It's a Pure Energy Tank and Reg. The only markings on the Reg are 3000 43-03. If that means anything more to you than me, great fill me in.

[questionful]

Well, it's the regulator you need to look at, I really don't know if there are markings on it to look for, but if you have a gauge lying around, air it up and see what it says.

The ULT has 3 shims. The Sear rod is close to the trigger. but doesn't move. .

Put additional shims in the ULT. What do you mean, "The sear rod doesn't move."?

When you air the gun up, the trigger rod should push forward, but the trigger should be able to move farther forward so that there is a tiny gap between the trigger rod and the back of the trigger.

[Temo Vryce]

Ok I finally got 5 minutes to play with this again and here are the findings.

1. It's well oiled. 3 drops in the macro fitting and oiled the on/off manually.
2. The Sear does move but there is resistance pushing back.
3. With 3 shims the mag fires once when gassed up.
4. With no shims or just 1 shim is doesn't fire on gassing up.
5. Removing the On/Off completely and gassing up I can feel the air flowing through the valve.
6. Velocity is turned up as high as it will go, also turned it down and still no change.
7. Valve will still not fire.

Further suggestions are highly appreciated.

Is there a gap between the back of the trigger and the front of the trigger rod when the mag is gassed up? There should be a tiny gap (credit card width). This part should be fine since you did fire it with a classic valve.

Put a couple more shims in the ULT.

Have you tried the X-valve with the on-off assembly from the classic valve? Do that to see if its the on-off assembly or the bolt assembly causing the problem. If it fires with the classic on-off, then you know its the ULT causing your problem. If it still won't fire, its a pretty good chance that it is your level 10 that is causing your problem.
