Introduction of Ball Valve

The ball valve was invented in the 1950s. Ball valves are one of the fastest-growing valves in recent years, especially in the USA, Germany, Japan, France, Italy, Spain and the UK where ball valves are widely used. The types and quantities of ball valves are still increasing rapidly and its engineering development is moving towards applications of high temperature, high pressure, large port, secure sealing, long duration, excellent adjustment and multiple functions. Due to the dedication to research and development, the stability and capacity of the ball valve has reached a high level, which is able to replace gate valves, check valves and throttle valves in applications. Ball valves are widely used in aerospace, petrochemical, pipeline, food and beverage, and construction.

Main Features of Ball Valve:

1. Low flow resistance

Ball valve passage can be divided into full port and reduced port. Whether full port or reduced port, its flow resistance factor is small, especially full-port type. A full-port ball valve has a passage diameter equal to the diameter of the pipe so that the partial resistance equals the frictional resistance of the pipe. Therefore, full-port ball valves have the lowest flow resistance compared to other types.

2. Quick and easy to open and close

Its 90-degree manual handle is easy and quick to open and close. In some cases, it only takes 0.05~0.1 seconds to complete the action. Hence it is preferable in automation system.

3. Great Sealing

Currently, most sealing components are made of flexible materials such as polytetrafluoroethylene, PTFE. Sealing elements combined with metallic and non-metallic materials are called soft sealing. In general, it is easy to guarantee the effectiveness of soft sealing and requires low machining precision and rough surface.

4. Long duration

The self-lubricating characteristic of PTFE reduces friction between the sealing element and the ball. In addition, improvements in machining skills reduce ball surface roughness, extending life.

5. The smooth surface of the passage facilitates the transport of viscous fluids, serous fluids and particles.

6. It can work smoothly without lubrication which is ideal for handling corrosive medium and low boiling-point fluids.

7. Under high pressure and temperature condition, it can do bi-directional sealing.

8. Sealing elements inside the body and seat can completely isolate the media that can prevent erosion.

9. Its compact construction and light weight is ideal for handling low temperature media.

10. Its symmetrical design, especially the welded ball valve, is easy to take the pressure from the pipeline.

11. Welded ball valves can be buried directly underground to prevent erosion of body components. The tenure can last up to 30 years. It is mainly used in oil and gas sector.
