Leakage In Ball Valves: Reasons Given By Top Ball Valve Manufacturers

Most manufacturers adhere to strict guidelines laid for the valve manufacturing process. Hence, the chances of any damage to the ball valves in their early stage of construction are minimal. Like every other product, ball valves are subjected to stringent quality checks before they are packed and shipped for distribution.

Here's where mishaps can occur, causing the ball valve to incur minimum or maximum damage that cause leakages. The most obvious reasons are:

• Lack of ample protection at the construction site.
• Lack of the installation of blind plates at both ends of the valve causing impurities to seep into the valve, thus causing leakage.
• Exposure of the valve to rainwater.
• Corrosion and rust due to the failure to subject the valve to anti-corrosion treatment.
• Improper packing and careless transportation can damage the integral valve and cause internal leaks.

Perfectly-made ball valves can start leaking if they are not properly installed. Here are some of the common mistakes people make while installing ball valves:

• Avoiding injecting grease into the valve seat will, in due course of time, allow impurities to enter into the rear of the valve seat.
• Damage due to welding spatters occurs when the ball valve is not installed in the fully open position.
• When the ball is drenched in welding spatter is opened and closed often, it will cause internal damage, thus resulting in internal leaks.
• The sealing surface is scratched by welding slag or construction debris.
• Misalignment of the ball valve stem drive sleeve during installation.

Causes for internal leaks in ball valves during operation(H2)

Most of the causes for leakage in ball valves occur after they are installed and used in the industrial process. Valve experts blame the lack of maintenance as one of the most common reasons for leakages. In many facilities, the operation manager avoids or postpones maintenance checks because of the expensive maintenance costs. Leakages are unavoidable if the device fails due to the lack of valve management and preventive maintenance. There are other reasons why ball valves leak while they are in operation:

• The construction residue scratches the sealing surface during the operation.
• Improper cleaning and maintenance of the pipelines.
• Long-term inactivity will cause the valve and ball to lock, thus damaging the sealing surface.
• Blockage in the stem that occurs due to debris like rust, dirt, and paint will not allow the valve to rotate in place.
• Dried and hardened sealing grease can accumulate behind the elastic valve seat and prevent the seat from moving freely, resulting in seat failure and leakage.

• Checking and adjusting the valve limit as soon as the leak is detected.
• Injecting grease to arrest the leakage.
• Cleaning the sealing surface with valve cleaning fluid.
• Discharging the impurities lodged in the back cavity.
• Checking the fully closed position.
• Repairing or replacing the valve on time.
