Ball valves are crucial components in industrial pipelines due to their simplicity, low flow resistance, and excellent sealing properties. However, like any mechanical equipment, ball valves can encounter common issues during operation, such as valve sticking, leakage, and seepage. In this article, we will delve into these typical ball valve problems and explore effective troubleshooting methods.
Valve Sticking:
Possible Causes:
Foreign particles or debris obstructing the valve.
Misalignment of the valve stem.
Wear and tear on the sealing surfaces.
Troubleshooting:
Remove any foreign particles or debris blocking the valve.
Realign the valve stem or consider replacing worn components.
Leakage:
Possible Causes:
Damaged sealing surfaces due to extended use.
Aging and softening of sealing gaskets.
Loose fasteners (e.g., bolts and nuts).
Improper installation.
Troubleshooting:
Replace the damaged sealing surfaces if they have been worn down.
Install new sealing gaskets if they have softened.
Tighten loose fasteners.
Reinstall the valve correctly if improper installation is the cause.
Seepage:
Possible Causes:
Aging and softening of sealing gaskets.
Damage to sealing components such as O-rings and packing.
Deformation of the ball.
Troubleshooting:
Replace aging and softened sealing gaskets.
Install new sealing components like O-rings and packing.
Replace the deformed ball to resolve seepage issues.
