    it would be good, if you can provide a seal kit for the regulating valve on the rear axle for SLS. In 2008 I made some pice when we disassembled it

    From the technical description of this valve made by the German company BARMAG, Model no. stamped in is VO011 34-1 or 84-1 (??)(difficult to see, although I used a steel brush):

    the minimum pressure valve is to keep the system pressure behind the valve not lower than p = 30 bar.
    The over pressure valve is limited to maximum p = 130 bar and opens then.
    Power steering pump pressure is 130-135 bar, the dual power steering pump feeds the LAD system.
    Pressure inside the regulating valve?
