This solenoid valve controls hydraulic flow to the tractor's remote valves and auxiliary circuits. It mounts in the hydraulic control manifold and receives electrical signals from the cab controls to shift the spool, directing pressurized oil to the selected port. A worn or sticking valve causes delayed or incomplete actuator movement, often accompanied by erratic pressure readings. The set includes the coil, three mounting bolts, and a gasket for the housing interface. The gasket should be replaced during reinstallation to prevent external leakage.
