Floating Ball Valve CF8 PN16

The ball of a floating ball valve is movable. Under the action of the medium pressure, the ball can produce a certain displacement and tightly press against the sealing surface at the outlet end to ensure the sealing at the outlet end. The structure of the floating ball valve is simple and has good sealing performance. However, the load of the working medium on the ball is all transferred to the sealing ring at the outlet end. Therefore, it is necessary to consider whether the material of the sealing ring can withstand the working load of the medium on the ball. When subjected to a higher pressure impact, the ball may shift. This structure is generally used for medium and low pressure ball valves.

product feature

1. Among various valves, ball valves have the least flow resistance. When a full-bore ball valve is fully open, the diameter of the ball passage, the valve body passage, and the connecting pipe diameter are equal and form a straight line. The medium can flow through almost without any loss.

2. A ball valve can be fully opened or closed by rotating 90 degrees, and it operates quickly. Compared with gate valves and globe valves of the same specification, ball valves are smaller in size and lighter in weight, making them convenient for pipeline installation.

3. Advanced valve seat: The valve seat, designed based on years of ball valve manufacturing experience, ensures a tight seal, has a low friction coefficient, and requires a small operating torque. There are various valve seat materials available, making it suitable for a wide range of applications.

4. Accurate handle: The flat-headed valve stem ensures that the connection with the handle will not be misaligned, thus guaranteeing that the handle indicates the correct open or closed position of the valve.

5. Locking device: To prevent misoperation when opening or closing the valve, there are locking holes at the fully open and fully closed positions to ensure the valve is in the correct position.

6. Anti-fly-off valve stem structure: The valve stem is installed from the bottom, preventing it from flying out under pressure. In case of a fire, it can form a metal contact with the valve body, ensuring the valve stem seal.

7. A ball valve uses a spherical body with a circular opening as the opening and closing component. Under the drive of the valve stem, the spherical body rotates around the center of the valve stem by 0 to 90 degrees to achieve the opening and closing function. It features a compact structure and quick operation. A 90-degree rotation can close the valve and cut off the medium in the pipeline. The diameter of the spherical body passage is the same as the pipeline diameter, resulting in low flow resistance and high flow capacity. The valve stem is installed from the bottom, eliminating the possibility of the valve stem flying out and ensuring safe use.
