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. Close and reliable. It has two sealing surfaces, and the sealing surface materials of the ball valve are widely used in various plastics, with good sealing performance, complete sealing and zero leakage. 4. It is easy to operate and open and close quickly. It only needs to rotate 90° from fully open to fully closed. 5, it is convenient to maintain, the ball valve structure is simple, the sealing ring is generally movable, and it is convenient to disassemble and replace. 6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes, it will not wash the valve sealing surface, and the service life of the valve is greatly increased. 7. It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and it can be applied from high vacuum to high pressure. 8. Because the ball valve has wiping properties during the opening and closing process, it can be used in some harsh working conditions with suspended solid particles.
