    X valve mistery

    Hello guys

    There's something my friend Seven7 and I don't understand.

    I've a Xvalve with ult on my rpg mag.

    When I use it with a HP tank, it leaks by the barrel, when I use it with a SHP tank, it works perfectly.

    The on/off orings are lubed and in good shape.
    We checked and cleaned every part of the on/off.
    I even tried to change the on/off

    Have you ideas ?

    Thanks

    When it leaks down the barrel, is it doing it because of bolt stick or is it just leaking all the time?

    Have you tried removing a shim from your ULT?
    Except for the Automag in front, its usually the man behind the equipment that counts.

    It leaks all the time.
    It leaks as soon as I put air.

    Yes I tried to remove a shim, without effect.

    Since it works with the SHP tank, its a small issue which to me sounds like velocity adjustment maybe increase some when using the hp tank. Check the velocity..

    When your mean by high pressure is it 800+?

    I was tweaking one of my markers last night and mistakenly screwed in a 400psi output tank which did the same thing you mentioned, installed a 850 and was butter. I would ck the pressure on that "HP" tank.

    Yeah some HP bottles sold recently are actually medium pressure output @ 650psi

    This has caught a few out when trying to run Mags on them... especially X-valves

    I would double check the bottle output
