The three valves are mainly composed of main components such as solenoid valves, cylinders, stroke switches, and flap systems. When the cylinder is running, the valve is pulled and the collision block is rotated. After turning to a certain angle, the collision block is touched by the collision block, and the cylinder rod stops moving to achieve the purpose of changing the material flow direction. The valve plate can be rotated in both positive and negative directions, and the angle of the discharge pipe is 45° and 60°

suitable for feed, flour, food, chemical, mining, metallurgy, cement, and other industries to control the flow of materials.
