Abstract: A high flow high pressure hydraulic solenoid valve (26) includes a proportional solenoid (56), a valve body (30) operatively associated with the solenoid (56), the valve body (30) having a valve bore (32) and at least one fluid inlet port (38) for fluid communication with the valve bore (32) and at least one fluid outlet port (40) for fluid communication with the valve bore (32), a valve member (42) axially and slidingly disposed within the valve bore (32), the valve member (42) having a plurality of valve elements (44) spaced axially along the valve member (42), and at least one of the valve elements (44) having a metering face (76a, 76c) adapted to control the pressure of pressurized fluid between the at least one fluid inlet port (38) and the at least one fluid outlet port (40) of the valve body (30) and including a flow force compensating annular void (78a, 78c) to meter out fluid flow from the at least one fluid inlet port (38) to the at least one fluid outlet port (40) to minimize hydraulic, steady state flow forces on the valve member (42) during high-flow conditions.
