Ok, I'm getting so confused of the ''Power beyond'' term, and research is giving me a lot of different answers.
We have a 5115M which I know has a gear pump so it is a open-center. However, the 5115 valve block on the back has an (plugged off) PB outlet and when I search for Power beyond on 5 series, I find a lot of those 'PB kits' which I really do not understand.
So in theorie; I can put a coupler on the PB port, an one on the oil return pipe and I would have continues oil pressure on it, correct? But then why do al those kits have a hose to connect the PB to the return when you don't use it? I mean, without a kit, the PB is plugged too.
We have a machine behind it which needs a continue oil pressure and has is own valve's, some one told me I could beter use a PB kit rather than the normal SCV Valves. But what is the benefit? As far as I can see it, the so called ''PB'' on these open-loop systems is nothing more then a SCV valve fully openend, the only thing I can thing of is the oil doesn't have to go through the SCV valve.. Or am I missing something?
