2026 Guide to Industrial Valve Selection for South African Mining Projects

Sep 16, 2026

South African mining operations require industrial equipment capable of handling demanding process conditions.

From platinum and gold to coal, manganese and other minerals, different processing environments create different valve requirements.

Start With the Process

Before selecting a valve, define the actual process duty.

Ask:

What is flowing?

Water, slurry, tailings, concentrate, sludge and chemicals all require different considerations.

How abrasive is it?

Particle hardness and concentration can have a major impact on valve selection.

What pressure is involved?

The valve pressure rating must match the actual system.

What temperature is expected?

Temperature affects seals and materials.

How frequently will the valve operate?

A frequently cycled valve may require a different configuration from an isolation valve that operates only occasionally.

Match the Valve to the Application

CMO Africa’s range covers different duties, including:

  • General industrial isolation
  • Water
  • Wastewater
  • Light slurry
  • Heavy slurry
  • High-pressure applications
  • Polyurethane-lined slurry service

The company’s published product range includes A, AB, GL, GD and XB Series valves, each aimed at different operating requirements.

Why Local Technical Support Matters

For South African projects, local technical support can help with:

  • Valve selection
  • Sizing
  • Material selection
  • Actuator selection
  • Replacement projects
  • Tender specifications
  • Spare parts

CMO Africa operates from South Africa and provides support for projects across South Africa and the wider African continent.

Final Consideration

Industrial valve selection should never start with:

“What is the cheapest valve?”

It should start with:

“What does this process require?”

Once the application is understood, the appropriate valve technology, materials and configuration can be selected.
