    Max Flow regulator

    Hello folks. I have recently started piddling around with my xvalve and a max flow max attack regulator on a 68/4500 tank. This weekend I was at a scenario and noticed an odd thing happening. I would turn the reg output on to about 900 or so and it would pressurize the trigger. I would play around with it turning it up but if I pulled the trigger a few times it would make the output gauge go down to 500 or 600 and stay there until I turned the reg up a slight turn. I did this a few times and I would finally get it right where it would kick the trigger back out just right. What is causing that? Why would it go from 900+ output pressure down to 500 and stay there? A few times I would get overzealous and turn a bit much and blow my macro line ( which I have sense decided is the devil). Is this a problem with my reg (its pretty old), my xvalve(I used a AA raptor reg before that worked fine. I just turned it up until the trigger pressurized and it worked fine, no output gauge), or do I just not know what I am doing? The last time I blew out the macro line and replaced it seemed to leak air out around that bleed hole on the left hand side of the valve. New to mags really and newer still to the xvalve and adjustable regs. Any help is appreciated

    I have a max flo inline that has been pretty sensitive to the amount of grease and dirt that is in it. Excess of either one usually gets me a leak thru the high pressure seal and I can hear the piston venting it off.

    Check out ZDSPB for maintenance info.

    It took me a while to learn how to take care of it since the guys at the SP tents were not any help when I let them rebuild it three different times.

    Two things that you don't see about the inline on ZDSPB;

    1) if your on/off keeps cutting its oring, you can polish the hole on the plug slightly and smooth it out enough to stop the cutting.

    2) if you need to replace the seal on the poppet (hopefully never), it is screwed together and loctite'd tighter than the top can withstand. Heat the assembly (melting the old seal and loctite) until the top loosens up, otherwise it will break off ($20 if you can find them).
