How to tell if a ball valve is faulty or damaged

Ball valves are a common type of valve that are widely used in various piping systems because of their simple structure, good sealing performance, and quick opening and closing. However, after long-term use, valves may fail or be damaged, affecting their normal operation. Here are some common ways to tell if a valve is faulty or damaged:

1. Observe external leakage

If liquid or gas leakage is found around the joints or valve body of the high flanged ball valve, it means that the sealing performance of the valve may be problematic. Leakage may be caused by aging, wear of the seal ring, or cracking of the valve body.

2. Check valve operation

When operating a ball valve, if you find that the valve is difficult to open and close or cannot be turned at all, it may be caused by the following reasons:

Stem stuck: The valve stem may be stuck due to corrosion, dirt, or impurities.

Ball wear: If the surface of the ball is worn or deformed, it will affect the opening and closing of the valve.

3. Abnormal flow

If the flow in the pipeline controlled by the three way ball valve is significantly reduced, it may be due to blockage inside the valve or improper ball position. At this time, check whether there are foreign objects or sediments inside the valve.

4. Abnormal sound phenomenon

When the valve is opened or closed, if you hear abnormal noise, such as friction or knocking, it may indicate that there is a fault inside the valve, such as inappropriate clearance between the valve stem and the valve body.

5. Temperature change

When the wafer ball valve is working normally, the temperature should be kept within the design range. If abnormally high temperature occurs, it may be caused by excessive fluid flow or friction in the valve.

6. Check the seal ring

Regularly check whether the seal ring of the valve is aging, cracked or deformed. Damage to the seal ring will cause the sealing performance of the valve to decrease, causing leakage.

7. Regular maintenance and inspection

Establishing a regular maintenance and inspection system can detect potential problems in advance. Maintenance includes cleaning the valve, checking the operating handle, lubricating the valve stem, etc.

There are many ways to determine whether the high mounting pad wafer ball valve is faulty or damaged. Timely detection and treatment of problems can effectively extend the service life of the valve and ensure the normal operation of the pipeline system. If problems are found during the inspection, it is recommended to contact professionals for repair or replacement in time to ensure the safety and reliability of the system.
