    Hmm Parker A8

    Must seem like a crazy question but what is the adjustment screw under the cap on Parker A8 inlet-- coil activated used for?

    Thanks

    You mean the little flathead screw under the hex cap?

    That is a manual open stem.

    When the stem is screwed full clockwise, the valve is in auto position.

    Back it off more than about a half a turn and that valve is wide open.

    As usual u saved the day Thank you very much!!!!! So use to sporlan SORITS These Parkers are different critters and more sensitive. Can you take these apart and come back in with a rebuild kit? I used to carry a rebuild kit for the sporlans 12, 15, and 20. Respectually 1 1/8, 1 3/8, and 1 5/8. Port size did not matter!

    The Parkers are actually easier to deal with.

    Get a gasket kit. One for the A8 and a different one for the A82.

    Back the adjustment stem out, tear the valve down, hose it real good with brake cleaner, clean the gasket parts off, put it back together.

    You win.

    Right on Ice just what I was looking for, thank you! Now if I can just understand what some of the letters and numbers mean. What does the A represent after the A8 in first colum at top? Since it says at the bottom that 1dessiggnates port size the 2 must be 15/8 on up? What is the B&S Ver. L Ver. BL Ver? And what is the 3 thru 11 13 thru 21 and 3 thru 11 on the A8 SPORT 11? How is the A8 SPORT 11 DIFFER from the A82?

    A8,- inlet pressure regulator
    A8L - diferential pressure regulator
    A8O , outlet pressure regulator

    throw a B in the mix (ex. A8BL) and that is for 'bypass" adds a solenoid to bypass regulation!
