Welcome to CMO Valves Africa: Engineered for Africa’s Toughest Pipelines

Let’s be completely honest: the African industrial landscape does not forgive weak equipment.

Whether you are pumping abrasive mining slurry in the Copperbelt, managing high-pressure municipal water grids in Gauteng, or running a complex chemical processing plant, your pipeline is only as reliable as the valves that control it. When a valve fails, it isn’t just an inconvenience—it means catastrophic downtime, flooded facilities, and skyrocketing maintenance costs.

For too long, African operations have had to settle for generic, “off-the-shelf” valves that simply aren’t built for the continent’s demanding operational realities.

That is exactly why CMO Valves Africa is here.

We are the dedicated African headquarters of CMO Valves, a global manufacturing leader with a footprint in over 70 countries. Operating out of Alberton, South Africa, we bring world-class European engineering directly to the African continent. We don’t just sell valves; we design, manufacture, and supply comprehensive fluid control solutions duty-matched to your specific application.

Here is a look at what we do, and more importantly, how we protect your pipeline.

Our Specialty: Heavy-Duty Knife Gate Valves

If you are dealing with raw sewage, paper pulp, or mining slurries, standard valves will get chewed up and destroyed in a matter of months. This is where our flagship product line comes in.

CMO Valves Africa specializes in manufacturing high-performance Knife Gate Valves designed to handle thick, abrasive, and solid-heavy fluids without clogging or failing.

• Unmatched Scale: We manufacture sizes ranging from DN50 all the way up to massive DN1200 units (with custom sizes available on request).
• High-Solids Capability: Our standard knife gate valves easily handle liquids containing up to 5% suspended solids, with specialized heavy-duty mining series available for extreme slurry environments.
• Bi-Directional & Uni-Directional Options: Engineered with advanced gate support guides, our valves provide watertight integrity even under severe pressure changes.

When the media is thick and the pressure is high, our knife gate valves are the ultimate line of defense.

Comprehensive Industrial Valve Solutions

While knife gate valves are our heavy-duty champions, a modern industrial plant requires a massive ecosystem of fluid control. CMO Valves Africa provides a complete, end-to-end manufacturing range for the water treatment, energy, chemical, and food/beverage sectors.

Our core industrial lineup includes:

• Butterfly Valves: (Double flange, wafer, and grooved) Engineered for low pressure-drop and 100% watertight sectioning in water supply and fire control facilities.
• Resilient & Metal-Seated Gate Valves: The backbone of clean water and potable water pump isolation.
• Penstocks & Dampers: Custom-built modular penstocks for dams, hydrological projects, and large-scale water treatment plants.
• Check Valves & Air Relief Valves: Critical infrastructure to protect your pumps from backflow and water hammer.

Why Partner with CMO Valves Africa?

You don’t just need a supplier; you need a technical partner.

Because we are the manufacturer, we have complete control over the quality, materials, and design of every valve that leaves our facility. We hold ISO 9001 certification and comply with all rigorous European Directives, ensuring that every piece of equipment meets the highest global standards for safety, resistance, and durability.

Furthermore, we understand that when you need a valve, you need it now. By maintaining significant stock levels of our most common valves right here in South Africa, we drastically cut down lead times, getting your plant back online faster.
