Maintenance Checklists: How to Extend Your Industrial Valve Life by 40%

In the African mining sector, “Run-to-Fail” is a liability. Data from CMO Africa site audits shows that a simple, disciplined maintenance checklist can extend the service life of slurry valves and knife gate valves by up to 40%.

The Weekly Visual Walkdown

• Check for “Weeping”: Look at the packing gland of your gate valves. Is there moisture or a dried crust?

• Inspect Actuators: Check the pneumatic lines on your control valves for audible air leaks.

• Pressure Check: Ensure your pressure valves are operating within their designated safety parameters.

The Monthly Operational Test

Valves that sit in one position for too long can “seize.”

• Full Stroke Cycling: Perform one full open-and-close stroke to clear the chest of the valve. This is especially important for knife gate valves in mineral processing.

• Material Care: Ensure your stainless steel valves are free from external contaminants that could cause pitting or surface corrosion in coastal environments.
