Ball Valve Maintenance

A rotating spherical ball with a bore inside regulates the flow in a ball valve. Meanwhile, the shaft connected to this ball and seat controls the ball’s movement.

General ball valve maintenance includes:

- Inspection of wear, tear, corrosion, as well as other damages.

- Ensuring accurate positioning and alignment.

- Performing pressure testing to identify the leakage.

On the other hand, the following are the potential problems that might arise during the continuous operation of ball valves.

Issues	Causes	Troubleshooting
Leakage	Worn stem seals or O-rings, corrosion, or damage	Replace seals/O-rings, tighten packing gland

Handle Breakage or Wear	Physical wear or improper handling	Change handle, ensure proper attachment
