Product Details

The working principle of a manual ball valve is to open and close the flow by rotating the spherical disc. As the ball rotates within the valve body's passage, it controls whether fluid flows through by changing its position relative to the valve's port. When the ball aligns with the valve's port, fluid can pass freely; when the ball is rotated perpendicular to the port, the flow is completely blocked. Manual ball valves typically feature a full-bore design, offering low fluid resistance and high flow capacity.

The structural features of manual ball valves primarily include the following aspects. First, the valve body and bonnet adopt a split design, making maintenance and seal replacement convenient. Second, the ball is designed with a full-bore configuration, reducing fluid resistance and enhancing flow efficiency. Third, a specialized sealing mechanism is employed between the ball and the valve body, ensuring excellent sealing performance—making it suitable for pipeline systems handling high-temperature, high-pressure, and corrosive media. Finally, the manual ball valve is equipped with a handle that allows users to rotate the ball simply and effortlessly by turning the handle itself.

Manual ball valves are widely used in fluid control systems across various industries. For instance, they are integral to transportation pipeline systems in the petrochemical industry, control systems within chemical equipment, and high-temperature, high-pressure systems in the metallurgical sector. These valves effectively manage the flow of fluids by enabling precise on-off control, while also delivering reliable sealing performance and excellent corrosion resistance—making them well-suited to handle diverse operating conditions and medium-specific requirements.

In summary, the manual ball valve, as a widely used fluid control device, boasts features such as simple operation, compact design, and reliable sealing, making it extensively applied across various industrial sectors. Looking ahead, as technology continues to advance, the performance of manual ball valves will further improve, offering even more dependable fluid control solutions for industrial production.
