    i have GC 250's and they get stuck open a lot. I don't like them. Get SMC's.

    A lot of that comes from bad judgment.

    I wouldn't use them, I just prefer SMC because I've had such luck with them.

    Re: GC Extreme vs parker vs others

    I am just gunna throw my 2 cent's in.
    I have installed GC's 250, Asco, Parker, AirLift, and SMC's on many customers rides. They are all good, some just do things a little better then others. All were 1/2 inch npt
    GC's 250: A good all-round valves. Low current draw. good value.
    Asco 300psi's: LOUD!! when used as dumps. Run these with a hopper and 0 problems even at 350-400 psi.
    Parker : Good reputation.
    AirLift: Retarded fast. They have a CV (flow factor) of 5.5 where most others have a cv of 4. Then comes the 300psi rating and "chrome" look. You get what you pay for with these.
    SMC's: Only installed 2 of these and had some issues with them sealing. I am not saying that they are bad just the ones that I had were troublesome.
