Hitachi excavator accessory YB60000571 pilot valve assembly; joystick

This product is a pilot control valve assembly specifically designed for the control lever of Hitachi excavator cab, which is a core component of the hydraulic pilot system. By the operator's action on the joystick, the mechanical displacement is accurately converted into a low-pressure pilot oil pressure signal, thereby controlling the main distribution valve and achieving smooth and precise control of the actions of the boom, forearm, bucket, and rotation.
