    Valve not firing

    Okay guys, I'm at the field shooting my Luke's Custom Deflator with an X valve and a tank at 1100psi.

    I can hear the low pressure valve cycling, but the valve itself isn't firing. The line from the lpr to the valve is aired up, so it should be getting air.

    Any ideas? Maybe the sear?

    I'm new to mags, so it might be a noob mistake.

    Thanks!

    You're running 1100 psi to you X valve?

        Okay I'm an idiot, I had to turn in the silver cap on the back of the valve. See, noob mistake.

        Now I could use some help adjusting the lpr. Right now the trigger only shoots single shots, although I can hear the lpr still cycling when I hold the trigger down.

              You did, but you had some trouble with the fittings so you couldn't test my actual valve.

                You dont need 1100 psi going to the xvalve, it's borderline unsafe, tune it down to about 900 psi

                  This is that the CCM fitting build that the orings wouldn't seal in the reanodized fittings, correct?

                    The LPR was already tuned, did you mess with that? (Just trying to figure out where you're at)

                      Your instinct is going to mess with the LPR, dont, focus on the X valve. Your input pressure (velocity adjuster) is likely to low.

                        Will do. Gotta vent 3000 psi now lol.

                          Correct, but I swapped out the anodized fittings for some black ones that work now.

                          Sorry about the multiple replies, I'm on mobile.

                            Nope, I figured you set it up right and that I shouldn't mess with it.

                              If you can hear the T-Rex venting and trying to fire, your LPR is close enough at this point. If you increase the pressure adjuster too much you may damage the LPR.
