In industrial production, high-pressure ball valves play a crucial role, and damage to the sealing surface may lead to leakage and performance degradation. Therefore, measures must be taken to prevent and protect the sealing surface.

1. Proper Operation and Usage

When operating high-pressure ball valves, it is essential to follow the correct operating procedures and technical requirements. Do not exceed the rated pressure and temperature range of the valve. Avoid over-tightening the valve to prevent damage to the sealing surface or premature wear.

2. Regular Inspection and Maintenance

Regularly inspect the sealing surface of the ball valve, especially valves exposed to high-pressure and high-temperature environments. Remove any debris and dirt around the valve to ensure the sealing surface is in good working condition.

3. Select Appropriate Sealing Materials

Choose suitable sealing materials according to the requirements of the working environment. For instance, in high-temperature or chemically corrosive environments, select sealing materials that are resistant to high temperatures and corrosion. Regularly inspect the wear and aging of sealing materials and promptly replace damaged seals.

4. Preventing Foreign Object Intrusion

Install filters or screens to prevent foreign objects from entering the valve body and damaging the sealing surface. Avoid conducting messy operations around high-pressure ball valves to reduce the intrusion of external impurities.

5. Timely Repair and Replacement

If damage or wear is found on the sealing surface, stop using it immediately and proceed with repairing or replacing the seals to prevent leaks from causing more serious issues.

6. Training and Education

Provide training to operators to ensure they understand the working principles and proper operation methods of high-pressure ball valves, reducing the risk of seal surface damage due to operational errors.

7. Minimize Frequent Opening and Closing

Reduce the frequency of opening and closing high-pressure ball valves because frequent operation increases wear and fatigue on the sealing surface, leading to premature failure. Where possible, take measures to minimize valve cycling, such as planning production schedules rationally or employing automated control systems.

8. Regular Cleaning and Maintenance

Perform regular cleaning and maintenance on high-pressure ball valves to remove accumulated dirt and deposits inside the valve body, ensuring the valve operates smoothly and the sealing surface remains clean. Regular cleaning effectively reduces contamination and corrosion of the sealing surface, extending the lifespan of the seals.

9. Choose High-Quality Ball Valves

Select high-quality high-pressure ball valve products to ensure that the design and manufacturing quality of the valves meet standard requirements and possess excellent performance and reliable sealing capabilities. Valves from DERVOS typically offer longer lifespan and better sealing effects, effectively reducing the risk of seal surface damage.
