The Advantages of Ball Valve

The Sanitary Ball valve evolved from the plug valve, and its opening and closing pieces are a sphere. It uses the ball around the stem axis of rotation at 90 °, to achieve open and close. The ball valve in the pipeline is mainly used to cut off, distribute and change the direction of medium flow.

Designed as a V-type open ball valve, also has a good flow regulating function. The ball valve not only has the advantages of simple structure and good sealing performance, but also has the advantages of small volume, light weight, less material consumption, small installation size, small driving torque, easy operation, and quick gas closing within a certain nominal size range, enabling it one of the fastest-growing valve types.

The application of ball valves is wide with high temperature, high pressure, large diameter, high sealing, long life, excellent regulatory performance, and a multi-functional direction development. Its reliability and other performance indicators have reached a high level.

With the development of the ball valve, it will be more widely used in oil and gas pipelines, oil refining and cracking units, offshore oil, and nuclear industries in the foreseeable short period of time.

The advantages of ball valves are as follows:

1. It has the lowest flow resistance.

2. It will not get stuck in the work, and it can be reliably used in corrosive media and low boiling point liquid.

3. It can be completely sealed at high working pressure and temperature range.

4. It can open and close quickly. Its opening and closing time in some structures is only half a second to one second to ensure that it can avoid impact on the test bed automation system.

5. The spherical closure can be automatically positioned in the external position.

6. Double-sided sealing is reliable.

7. When it is fully open and fully closed, the ball with the seat sealing surface and the media are isolated. Therefore, high speed through the valve medium will not erode the sealing surface.

8. It is designed as a V-type open ball valve, with good flow adjustment.

9. Its compact size and light weight make it the most rational valve structure for cryogenic media systems.

10. Its body is symmetrical, and especially the welder body structure can well withstand the stress from the pipe.

11. Closures can withstand the high-pressure differential when closed.
