1. Due to the wiping property of ball valves during opening and closing, they can be used in media with floating solid particles;
2. Low fluid resistance, with almost no flow resistance for full bore ball valves;
3. Simple structure, small size, and light weight;
4. Tight and reliable, it has two sealing surfaces, and currently the sealing surface materials of ball valves are widely used with various plastics, with good sealing performance;
5. It can achieve complete sealing. It has also been widely used in vacuum systems;
6. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be applied from high vacuum to high pressure;
7. Convenient operation, quick opening and closing, with only 90 "rotation from full opening to full closing, facilitating remote control;
8. Convenient maintenance, simple ball valve structure, and generally movable sealing rings, making disassembly and replacement more convenient;
9. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.
