Having some trouble understanding the schematic / plumb for a hydraulic valve. The valve will be used to control a double action hydraulic cylinder powered by hydraulic gear pump (not sure if this is the correct term, the type with the 2 gears that mesh into each other similar to an oil pump in a car, constant flow).
On the schematic there is a pressure and tank port and an A and B port their function is clear to me, however there are also 2 N ports on the schematic, however I reality there is only one N port on the valve (blocked off from factory with a plug). I assume the function of the N port is that when the valve is in neutral oil flows freely through the valve back to the reservoir. How do I plumb this, do I just go from the N port to the oil return hose and that way the oil flows back or is there more to it?
Valve in question: A and B port on top, P and T port on the side and then the one blocked of N port on the left hand top corner.
