Sanitary Ball Valve Low fluid resistance: The ball valve has the smallest fluid resistance among all valve types. Quick and convenient switching: As long as the valve stem rotates 90°, the ball valve will complete the full opening or closing action, and it is easy to achieve rapid opening and closing. The valve seat has good sealing performance. Most ball valves are made of elastic materials such as polytetrafluoroethylene. The soft sealing structure is easy to ensure the unsealing, and the sealing force of the ball valve increases with the increase of the medium pressure. The valve stem seal is reliable.

When the ball valve is opened and closed, the valve stem only rotates but not lifts and lowers. The packing seal of the valve stem is not easy to be damaged, and the sealing force of the valve stem reverse seal increases with the increase of the medium pressure. Since materials such as polytetrafluoroethylene have good self-lubrication and small friction with the ball of the ball valve, the ball valve has a long service life. The raw-grade non-retained liquid ball valve can be equipped with a variety of drive mechanisms such as pneumatic, electric, and hydraulic to achieve remote control and automatic operation. The inner channel of the ball valve body is flat and smooth, and can transport viscous fluids, slurries and solid particles.

The following is a brief introduction to the characteristics of sanitary external thread ball valves, as shown below:

1. Easy maintenance, the ball valve has a simple structure, the sealing ring is generally movable, and it is convenient to disassemble and replace.

2. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when passing through.

3. Wide range of applications, diameters range from a few millimeters to several meters, and can be used from high vacuum to high pressure

4. Easy to operate, open and close quickly, only need to rotate 90° from fully open to fully closed, which is convenient for long-distance control.

5. Small fluid resistance, its resistance coefficient is equal to that of the pipe section of the same length.

6. Simple structure, small size and light weight.

7. Tight and reliable, the sealing surface material of the ball valve is widely made of plastic, with good sealing performance, and has also been widely used in vacuum systems.
