Claim 0:
1. An electrohydraulic valve system for controlling a braking system of a work machine, comprising:
a valve body forming a bore and a fluid channel;
a valve spool disposed within the bore and in fluid communication with the fluid channel, the valve spool including at least a first land and a second land;
an armature positioned with respect to the valve spool to move the valve spool axially within the bore between a first position and a second position;
a spring disposed within the bore and biasing the valve spool to its first position;
a first electromagnetic coil and a second electromagnetic coil arranged relative to one another and the armature for forming a magnetic field when energized;
a detent system positioned within the valve body, the detent system configured to exert a force to the valve spool or armature; and
a controller in electrical communication with the first electromagnetic coil via a first communication link and in electrical communication with the second electromagnetic coil via a second communication link, the first communication link and the second communication link independent from one another.
