California,
On the schematics you posted on post #49 The second schematic does not show a relief for the 3PH. The relief valve shown for the 3PH is down stream of the control valve and would act more like a surge relief than a system relief. The first schematic with the two spool directional also shows a relief that is connected to tank and the nomenclature also states it must go direct to tank.. What that schematic does not show is which line goes to the 3PH valve.
