Claim 7:
8. The hydraulic control assembly of claim 1, wherein the hydraulic valve includes:
a coil assembly mounted to the valve body, the coil assembly including a coil, an armature, and a pole piece, the coil disposed around the armature, the pole piece and the armature disposed within the internal cavity of the valve body, the pilot spring disposed between the pole piece and the armature, and the armature disposed between the pilot spring and the pilot-operated valve;
wherein an electric current applied to the coil provides a magnetic force acting on the armature that causes motion of the armature toward the pole piece such that the closing spring force can be selectively adjusted, thereby adjusting the threshold pressure.
