Abstract
A hydraulic magnetic control valve includes a base with an inlet and an outlet. A plug provided with a second magnetic member formed thereon is arranged above the outlet of the base for controlling the hydraulic flow, and the top surface of the base is mounted a driving motor. One of the side walls of the base is in a form of a slanted side wall, on which a first magnetic member is slidable upward or downward along the slanted side wall under control of the driving motor. When the first magnetic member slides downward along the slanted side wall, the control valve is in open situation permitting hydraulic material flow from the inlet to the outlet, while the first magnetic member slides upward along the slanted side wall, the control valve is in closed situation thereby stopping up the flow.
