Abstract
A hydraulic control valve is provided having a solenoid body, an energizable coil, and an armature positioned adjacent the coil. A valve stem extends from the armature. The coil is energizable to move the armature and the valve stem from a first position to a second position. The valve body, the armature and the valve stem are configured so that the armature and the valve stem are biased to the first position by pressurized fluid, allowing the armature to operate without a biasing spring.
