Winkler, Manitoba Canada | 9684 would be closed centre load sensing hydraulics in the steering circuit.
9680 would originally be open centre hydraulics on the steering circuit. If it has been converted to hi-flow, the steering circuit would be closed centre load sensing like the 9684.
In any case the hydraulic circuit for the hi-flow system is a hybrid. A gear pump is feeding a load sensing priority valve which determines the flow to the steering circuit and the remainder is supplied to a secondary load sensing priority valve which supplies the auxiliary valves with supplemental oil. | |
