In the present study, we succeeded in improving an oil hydraulic ball valve using the visualization technique, in order to prevent the vibration, cavitation and the noise of the ball valve. The valve body outside of the ball is made of transparent acrylic resin to observe the flow and the motion of the ball. The cavitation cloud near the orifice in the valve, and the movements of the ball, the ball support and the spring during cavitation and the vibration of the ball are observed using a commercially available digital video camera, a high-speed video camera and X-rays. After the generation of the cavitation and the vibration of the ball inside the conventional ball valve are visualied in detail, new types of the ball valve without the lateral oscillation are designed to obtain good performance. It is confirmed that one of the new types of the valve has no cavitation bubble and no cavitation noise. Furthermore the upstream pressure of the valve is measured and discussed from the vibration point of view.
