Abstract

An electrohydraulic valve system for controlling a braking system of a work machine includes a valve body forming a bore and a fluid channel, and a valve spool disposed within the bore and in fluid communication with the fluid channel. The valve spool includes at least a first land and a second land. An armature is positioned with respect to the valve spool to move the valve spool axially within the bore between a first position and a second position, and a spring is disposed within the bore for biasing the valve spool to its first position. A first electromagnetic coil and a second electromagnetic coil are arranged relative to one another and the armature for forming a magnetic field when energized, and a detent system is positioned within the valve body for exerting an axial force to the valve body or armature.
