2. It has simple structure, small size and light weight.
3． Tight and reliable, plastic is widely used as the sealing surface material of ball valves at present, with good sealing performance, and has also been widely used in vacuum systems.
4. It is easy to operate and opens and closes quickly. It only needs to be rotated 90° from fully open to fully closed, which is convenient for long-distance control.
5. It is easy to maintain. The ball valve has a simple structure and the sealing ring is generally movable, making it easy to disassemble and replace.
