1.Smallest resistance with the fluid-by zero in fact.
2.The ball is free to bare the high pressure when it closed.
3.Quickly to open and close (some components need only 0.05s-0.1s), to be assure to used in the automatic system of test bed.
4.Tightly connected components, with small volume and light weight.
