Hydraulic fluid is pulled from the Hydraulic Tank to the suction port of the Hydraulic
Pump. Pressurized fluid leaves the pump and goes to Proportional Valve. From the
Proportional Valve, fluid goes to Port P of the Functions Manifold and to the Load
Sense port of the pump. Unused fluid is routed back to the tank through Port T of the
Functions Manifold. Pump case pressure drains back to the tank.
