Common incorrect maintenance methods lead to premature damage of ball valves:

Using inappropriate cleaning agents: Using strong acids, alkalis, or other corrosive cleaning agents may damage the material surface and internal seal of the ball valve.

Overtightening fasteners: Overtightening bolts may cause deformation or damage to the valve body or flange connection.

Insufficient lubrication or use of incorrect lubricants: Insufficient lubrication can increase wear, while using incompatible lubricants may cause chemical reactions or blockages.

Neglecting regular inspections: Irregular inspections of the sealing performance and operating mechanism of ball valves may lead to small problems developing into major malfunctions, such as leaks and inflexibility in operation.

Storage in inappropriate environment: Storing ball valves in damp or corrosive environments can accelerate their corrosion and damage.

Improper operation: Applying excessive torque when the ball valve is not fully opened or closed may damage the valve stem or ball.

Neglecting maintenance records: Without maintenance records, the maintenance cycle of the ball valve may be overlooked, resulting in missing key maintenance and component replacement opportunities.

Avoiding incorrect maintenance methods can significantly extend the service life of ball valves.

When choosing a lubricant suitable for ball valves, you need to consider the following factors:

Working medium: Lubricants should be compatible with the working medium of ball valves to avoid chemical reactions or dissolution.

Working temperature: The lubricant should be able to maintain stability within the working temperature range of the ball valve, without decomposition or solidification.

Pressure conditions: Ball valves operating in high-pressure environments require lubricants with good compressive performance.

Sealing performance: Lubricants should provide good sealing performance to prevent leakage.

Chemical stability and corrosion resistance: Lubricants should have high chemical compatibility and excellent corrosion resistance to protect ball valves from corrosion by chemical media.

Lubrication performance: Lubricants should have excellent lubrication performance to reduce wear and extend the service life of ball valves.

Environmental friendliness: Consider using eco-friendly lubricants, which aligns with sustainable development goals and benefits both employees and the environment.

Convenience of maintenance and application: Choose lubricants that are easy to apply and maintain to reduce downtime and maintenance costs.

Based on these factors, you can choose the appropriate lubricant to ensure the reliability and performance of the ball valve. In practical applications, it may be necessary to choose the most suitable lubricant product based on the specific working conditions of the ball valve and the manufacturer's recommendations.
