Directional valves are used to open or close oil passages in hydraulic systems or change the direction of oil flow, thereby controlling the actuation or stopping of hydraulic actuators and altering the direction of motion of these actuators. Building upon its legacy Yoken series of directional valves, the company has successively developed several new products, including directional valves equipped with emergency manual levers and directional valves with position monitoring capabilities, to meet the diverse requirements of different customers under varying operating conditions.
