A Yuken Hydraulic Valve is a mechanical actuator that converts hydraulic energy (pressurized fluid) into rotational mechanical power (torque and shaft rotation). In a hydraulic system the pump generates pressurized fluid, and the hydraulic valve uses that fluid flow to produce torque and rotation for driving machinery.
Yuken is a long-established Japanese manufacturer of hydraulic components — including pumps, valves, cylinders, power units, and hydraulic motors — known for precision engineering and reliability in industrial and mobile hydraulic systems.
