Advantage:

1. It has the lowest flow resistance (0 actually);

2. It can be reliably used in corrosive medium and low boiling point liquid because it will not get stuck in operation (without lubricant BAI);

3. In a large range of pressure and temperature, it can achieve complete sealing;

4. It can realize fast opening and closing, and the opening and closing time of some structures is only 0.05 ~ 0.1s, so as to ensure that it can be used in the automation system of the test bed. When the valve is opened and closed quickly, the operation has no impact.

5. The spherical closing part can be positioned on the boundary automatically;

6. The working medium is sealed reliably on both sides;

7. When the valve is fully opened or closed, the sealing surfaces of the ball and valve seat are isolated from the medium, so the medium passing through the valve at high speed will not cause the erosion of the sealing surface;

8. Because of its compact structure and light weight, it can be considered as the most reasonable valve structure for low temperature medium system;

9. The valve body is symmetrical, especially the welded valve body structure, which can well withstand the stress from the pipeline;

10. The closing part can withstand the high pressure difference when closing.

11. The ball valve with all welded valve body can be directly buried in the ground, so that the internal parts of the valve will not be corroded, and the maximum service life can reach 30 years. It is the most ideal valve for oil and gas pipelines
