The advantages of brass ball valve:
1. The fluid resistance is small, and the full-bore ball valve basically has no flow resistance.
2. Simple structure, small size and light weight.
3. Tight and reliable. It has two sealing surfaces, and various plastics are widely used for the sealing surface materials of the ball valve at present, which has good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems.
4. Convenient operation, quick opening and closing, only need to rotate 90° from fully open to fully closed, which is convenient for long-distance control.
5. The maintenance is convenient, the ball valve has a simple structure, the sealing ring is generally movable, and it is more convenient to disassemble and replace.
6. When fully open or fully closed, the sealing surfaces of the sphere and the valve seat are isolated from the medium, and the sealing surface of the valve will not be eroded when the medium passes through.
7. Wide range of applications, diameters ranging from small to several millimeters, large to several meters, and can be applied from high vacuum to high pressure.
8. Because the ball valve has wiping property during the opening and closing process, it can be used in the medium with suspended solid particles.
