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;
