Low fluid resistance, with a resistance coefficient equal to that of pipe sections of the same length. 　　2. Simple structure, small size, and light weight. 　　3. Tight and reliable; currently, plastic is widely used as the material for the sealing surfaces of ball valves, providing good sealing performance, and it is also extensively utilized in vacuum systems. 　　4. It is easy to operate and opens/closes quickly; only a 90° rotation is required to go from fully open to fully closed, facilitating remote control. 　　5. It is easy to maintain; the ball valve has a simple structure, and the sealing rings are usually movable, making disassembly and replacement straightforward. 　　6. When in the fully open or fully closed position, the sealing surfaces of the ball and the valve seat are separated from the medium; thus, as the medium passes through, it does not cause erosion of the valve’s sealing surfaces. 　　7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and it can be used in conditions ranging from high vacuum to high pressure. When the sphere rotates 90 degrees, its surface should be fully visible at the inlet and outlet, thereby interrupting the flow.
