Used to control the oil opening, stop and flow direction. Ball-type solenoid operated valves, flow direction along the closed sealed tight, long time under the pressure without hysteresis phenomenon. Rationale: When the solenoid is energized, the solenoid (2) the role by Angle lever (6) and the ball (7) acting on the push rod (8), closed at both ends of the putter. P mouth cavity and connected between the ends closed. Therefore, the seat system (3) In addition to withstand operating force (electromagnetic force and the spring force) of the small remaining area, almost perfectly balanced. Such valves therefore can be used under conditions of a pressure of up to 63Mpa. In an initial position, the ball (4) is a compression spring (9) toward the valve seat. When changing position, the electromagnet (2) to push it away from the seat.
