What should I do if the valve is leaking?

What are the possible reasons for a ball valve leakage?

1. Improper installation: Incorrect installation can result in poor valve sealing, leading to gas or liquid leakage.

2. Aging or damage of sealing ring: The sealing ring of the ball valve can age over time or be damaged during use, resulting in gas or liquid leakage.

3. Surface damage of ball body: Wear, scratches, or corrosion on the surface of the ball valve body can damage the sealing performance and cause leakage.

4. Loose or damaged threads: If the threads at the connection of the ball valve are loose or damaged, the sealing effect can be affected, resulting in gas or liquid leakage.

5. Material fatigue caused by high pressure or high temperature: The material of the ball valve may deform or fatigue under high pressure or high temperature, affecting the sealing performance and causing gas or liquid leakage.

6. Improper operation: Users may excessively close or open the ball valve or fail to properly close the valve, causing leakage.

7. Other factors: Improper selection of ball valve materials, manufacturing defects, and other factors may also cause gas or liquid leakage in ball valves.

How to repair a leaking ball valve?

1. Stop gas or liquid supply: First, you need to close the ball valve to stop the supply of gas or liquid to prevent further leaking.

2. Inspect the valve seal: Check if the seal of the ball valve is aging, damaged, or ineffective. If any issues are found, replace the seal with a new one.

3. Inspect the ball surface: Check if the ball surface of the ball valve is damaged, worn, or corroded. If there is damage, you can try repairing or replacing the ball.

4. Inspect the threaded connection: Check if the threaded connection of the ball valve is loose or damaged. If there are any issues, tighten or replace the threaded connection.

5. Inspect material fatigue: If the ball valve experiences material fatigue due to high pressure or high temperature environments, you may need to replace it with a valve that is resistant to high pressure and high temperature.

6. Operate the ball valve correctly: Ensure that you operate the ball valve correctly, without excessive closing or opening, and close it properly to ensure sealing performance.

7. Seek professional help: If self-repairing fails to solve the issue of gas or liquid leakage in the ball valve, it is recommended to seek professional valve repair services or consult the supplier for repair or replacement.

Please note that ball valve repair may involve safety issues. To ensure the safety of personnel and equipment, please perform the repair under the guidance of individuals with relevant knowledge and experience.
