problem with xvalve on/off assembly

[shocker]

I just got a used xvalve, and I'm having a few problems with it. here is the problem explained as best as possible:

whenever I gas up the gun, nothing happens. the gas goes through the hose and into the valve, but whenever I pull the trigger, the bolt doesn't cycle. however, the trigger sear is stiff, and when the trigger is pulled, the trigger sear pushes the trigger back to its original position, as if it had shot. I played around with the nut on the back of the valve, turning it as tight as possible and then backing it off slowly, and still nothing happened. I changed to a different air system, was running at around 700 psi, and still the same result. also, I know that air is running into the valve, so that is not the problem. anyway, I've got the 1.0 carrier in the level 10, as the 1.5 leaked, so not sure if that has anything to do with it. however, one thing I noticed is that the on/off assembly in the valve is not flush with the body of the valve (as it was in my old valve, an RT). it sticks out about 1 mm, making it slightly difficult to slide the bolt into the gun, and often requires a little bit of force to get it in. this leads to me to believe that the problem has something to do with the on/off assembly. anyway, my gun setup is as follows: micromag, 68/45 max flow or 68/3k armageddon.

please, if anyone has any insight into this problem, or can direct me to someone who might know, please post asap as I am without a gun. you can also email me at [email protected]. thanks

Sounds like the on/off pin is too long. Measure the length of the pin. It should be .750".

Since you have a MicroMag, you need to have those guns individually tuned to get things working right on them since their tolerances are so far off.

[shocker]

when you say 'get "them" tuned' did you mean the gun in general or the on/off pin length? and if it is the gun, do I (or should I) send it in to pro team to get it tuned? better yet, whee would I get it tuned? if you know the answers to these questions let me know. thanks

[shocker]

also, I just measured the on/off pin length, and it's about 1/16 of an inch too short ... not sure if that helps at all.

and, I just to want to reiterate that the RT I had before the xvalve worked flawlessly, and as I mentioned earlier did not have an on/off assembly that protruded from the valve body.

[BlackVCG]

The on/off pushing out of the body is perfectly fine. When the valve is gassed up, it pushes out until it comes into contact with the mainbody, so how far out or in it is when you put it in the gun is a moot point.

If you have the old RT valve, try the on/off assembly out of it, or just the pin. The pin length is what's probably giving you problems.

[shocker]

okay ... so it seems like my on/off pin is too long. two things: how do I find out how much I need to shorten it and then how do I go about shortening it? let me know.

also, so not to be a complete ***, thanks for the help so far. this is really helping me out.

oh, and I sold the rt valve, so no go on that.

regarding the on/off assembly sticking out of the valve body: when I slide the bolt into the gun, the on/off assembly hits the frame of the gun and stops it from sliding in. generally I have to use a knife or something as a lever to lift the bolt higher so that the small part of the height of the on/off assembly that's hitting the gun body can get over that part of the gun. I don't think this is normal since the rt assembly was flush with the valve body and required no extra effort to slide it into the body.

You can buy new on/off pins in the AGD store, http://store.airgun.com/acb/showdetl...ID=132&CATID=6 I had similar problems w/ my micro when I tried to put a Retro Valve in it. I just put my Boo-yaah frame on it and switch to a classic valve tho. Trying to shorten your on/off will be hard to do properly unless you have a good pair of calipers, and/or have a couple of extras in case you ruin some. I have some nice classic valves I could trade you for that X if you just wanna get rid of that problem

[shocker]

any insight BlackVCG? anything I can do to remedy the problem? I don't really want to sell the x, so sorry Magician.

how about exteding your fireing rod?

pull it out a turn or two..

thats waht it sounds like to me in hte first place...I had the same problem when my Rod screwed it self in....there would be preshure beind the trigger..but the bolt wouldint realse....when I realzed my rod had screwed itself in...I put some teflon tabe around the threds and screwed it back...to where is should be for my trigger...and it worked fine after that.

I would recomend giveing that a shot.

[shocker]

what exactly is the firing rod? I looked at the manual for the xvalve and there was nothing listed under that name. also, Surfer, were you using a micromag, or a different type of mag? let me know. thanks

[TAW]

What surfer is saying is with your valve gassed up hold your trigger forward. There should be a gap between the trigger and trigger rod no bigger than a credit card and if the rod touches the trigger it's too tight.

The trick to putting in the valve. When you put your xvalve in the body and it hangs up on the on/off valve,take your field strip screw and push up the on/off valve through the field strip hole in the frame.

BlackVCG realy needs the measurement of your on/off pin in inches(0.7??") to make a guess at how long of a pin you need.

[SkyBoySurfer]

well you never specified that you where using a electronic gun...you where just talking about the valve.


Altho...the same princibale should still apply...only in just a difrnt location.....But it would probibly be easyer to replace your pin..if you are using a electric.

And if you dont know what your fireing Rod is look at TAW's post.

you need to bring your rod closer to your trigger.

[shocker]

micromags aren't electronic guns.

also, my on/off pin is roughly 11/16" if that helps.

[shocker]

all right, I'm gonna try to measure the on/off pin with a pair of calipers, because rulers suck. I talked to a tech at AGD today, as well as one at PTP, and the consensus was the same: on/off pin is too long (which was BlackVCG's solution to begin with). Anyway, that's probably the problem, and once I grind it down to the required length, I'll test it out. hopefully it will work, and if not, I'll be back here for more help.

Again, thanks to all of those that posted their insight.

[BlackVCG]

Yes, you need to measure the length with calipers. Shorten in .005" increments.
