Leakage: One of the most common problems is valve leakage, which can occur due to worn-out seals, damaged seats, or improper installation. To resolve leakage, the seals or seats may need to be replaced, or the valve may need to be reinstalled correctly.
Sticking or Binding: Ball valves can sometimes become stuck or bind, making it difficult to open or close the valve. This can be caused by debris, corrosion, or improper lubrication. Cleaning the valve, applying appropriate lubrication, or replacing damaged components can help resolve this issue.
Excessive Torque Requirement: If the valve requires excessive torque to operate, it can indicate issues such as misalignment, damaged bearings, or excessive friction. Adjusting the alignment, replacing bearings, or lubricating the valve can help reduce the torque requirement.
Seat Damage: The valve seats can get damaged due to erosion, corrosion, or wear. This can lead to leakage or improper sealing. Resurfacing or replacing the seats can resolve this problem.
Stem Leakage: Stem leakage can occur if the stem packing is worn out or damaged. Replacing the packing or adjusting the packing gland can help stop the leakage.
Actuator Malfunction: In automated valves, the actuator can sometimes malfunction, leading to valve operation issues. Troubleshooting the actuator or replacing faulty components can resolve this problem.
Cavitation or Erosion: High-pressure applications can cause cavitation or erosion in the valve body or trim, leading to damage and reduced performance. Selecting materials with better resistance to cavitation and erosion or installing protective coatings can help mitigate this issue.
Regular maintenance, including inspection, cleaning, lubrication, and component replacement, can help prevent and resolve many problems with high-pressure ball valves. It is also important to follow manufacturer guidelines and industry best practices for installation, operation, and maintenance to ensure optimal performance and longevity of the valves.
