International Logistic Service The proportional directional valve is a key component used to control the flow direction of fluid in a hydraulic system. Its main function is to adjust and control the flow ratio of liquid in the hydraulic system to ensure that each part of the system receives appropriate hydraulic pressure and flow. By adjusting the proportional directional valve, the movement speed and direction of hydraulic actuators (such as hydraulic cylinders or hydraulic motors) can be precisely controlled, thereby achieving precise control of the mechanical system. Proportional directional valves are widely used in engineering, manufacturing and automation fields to improve system responsiveness and efficiency while also providing engineers with greater flexibility to meet different application needs.
