1.Ball valve design:

The design of ball valve includes the structure of the valve body, the seat and the ball. Reasonably designed ball valve can provide better sealing performance.

2.Sealing materials:

The commonly used sealing materials for PPR ball valves include PTFE (polytetrafluoroethylene) and EPDM (ethylene propylene rubber). These materials have good corrosion resistance and sealing properties, which can effectively prevent leaks.

3.Compression force:

When installing ball valves, proper compression force is essential to ensure sealing performance. Too low or too high a compression force can cause leakage problems.

4.Temperature and pressure:

Changes in temperature and pressure will affect the sealing performance of the PPR ball valve. The ball valve must be selected to meet the requirements of the working conditions and ensure that it can withstand the corresponding temperature and pressure.

5.Testing and verification:

Pressure testing and leak detection are important methods to verify the sealing performance of PPR ball valves. Through these tests, potential leakage problems can be detected and repaired in a timely manner.

6.Ball valve structure type:

PPR ball valves usually have two main structure types, that is, full diameter ball valves and color ball valves. The ball diameter of the full diameter ball valve is the same as the inner diameter of the pipe, which can provide lower flow resistance and better sealing performance. The color ball valve uses a smaller ball diameter and is suitable for smaller pipelines.

7.Sealing surface design:

The sealing surface is formed between the valve seat and the ball. The high quality sealing surface design can provide better sealing effect and prevent leakage. Common designs include V-type sealing surface, O-type sealing surface and so on.

8.Cleaning and maintenance:

Regular cleaning and maintenance of PPR ball valves is key to maintaining their sealing performance. During use, dirt, particles or chemicals may accumulate on the sealing surface, affecting the sealing effect. Therefore, regular cleaning and inspection of the ball valve and ensuring that the sealing surface is clean is an important step to maintain the sealing performance.

9.Sealing performance grade:

According to different application requirements, the sealing performance grade of PPR ball valve can be different. Some ball valves have higher sealing performance grades and can withstand higher pressures and temperatures. When selecting the ball valve, it is necessary to select the appropriate sealing performance level according to the specific working conditions.

10.Anti-static design:

For some special application scenarios, such as conveying flammable and explosive media pipeline systems, PPR ball valves also need to have anti-static design. This design effectively prevents the build-up of static electricity and reduces the risk of fire or explosion.

11.Valve operation and sealing performance:

Proper operation and maintenance of ball valves is also critical to their sealing performance. Incorrect operation may lead to damage or wear of the ball valve sealing surface, which will affect its sealing effect. Therefore, when using ball valves, you should follow the correct operating procedures and carry out regular maintenance.

In summary, understanding and paying attention to these factors and taking appropriate maintenance measures can ensure the good sealing performance of PPR ball valves, thereby preventing leakage problems and maintaining the integrity and efficient operation of the pipeline system.
