Industrial Valve Selection Checklist
Industrial Valve Selection Checklist: 15 Questions Engineers Should Ask Selecting an industrial valve should start with the application, not the valve catalogue. A valve that works perfectly in one pipeline may be unsuitable for another. The best approach is to...
How Often Should Industrial Knife Gate Valves Be Inspected?
How Often Should Industrial Knife Gate Valves Be Inspected? There is no single maintenance interval that works for every industrial valve. The correct knife gate valve maintenance frequency depends on the application. A valve handling clean water under stable...
Knife Gate Valve vs Butterfly Valve
Knife Gate Valve vs Butterfly Valve: Which Is Better for Your Application? When selecting an industrial isolation valve, engineers often compare different valve technologies. Two common options are knife gate valves and butterfly valves. But which is better? The...
8 Common Knife Gate Valve Installation Mistakes
8 Common Knife Gate Valve Installation Mistakes and How to Avoid Them Installing a knife gate valve correctly is just as important as selecting the right valve. Even a high-quality valve can experience problems if it is incorrectly installed. Poor alignment, incorrect...
Which Knife Gate Valve Spare Parts Should Mining Operations Keep?
For a mining operation, a valve failure can affect much more than the valve itself. If a critical pipeline has to be shut down while a replacement component is sourced, the resulting downtime can become expensive. This is why knife gate valve spare parts should be...
Cavitation vs Abrasion in Industrial Valves
Industrial valves can experience different types of wear and damage. Two terms that are often confused are cavitation and abrasion. They are not the same problem. Abrasion is associated with solid particles wearing against surfaces. Cavitation is associated with...
Where Should Valves Be Installed on a Slurry Pipeline?
A slurry pipeline can transport some of the most challenging media found in industrial processing. Mining slurry may contain high concentrations of mineral solids, water and other process chemicals. The pipeline therefore needs reliable isolation points. Correct...
Knife Gate Valve Flange Standards
A knife gate valve flange connects the valve to the surrounding pipeline. It may look like a simple mechanical connection, but flange compatibility is an important part of valve selection. If the valve and pipeline connections do not match, installation can become...
2026 Guide to Industrial Valve Selection for South African Mining Projects
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...
Valve Lifecycle Cost: Why the Cheapest Industrial Valve Can Cost More
When purchasing industrial valves, price is naturally an important consideration. But purchase price is only one part of the total cost. The Real Cost of a Valve A useful way to think about valve cost is: Purchase + installation + maintenance + spares + downtime +...
How Climate and Site Conditions Affect Industrial Valve Selection in Africa
Industrial valves installed in Africa can face environmental conditions that are very different from those encountered in temperate regions. The process media is only one part of the engineering equation. Temperature Large temperature variations can affect: Elastomers...
What Is the Difference Between a Knife Gate Valve and a Slurry Valve?
The terms knife gate valve and slurry valve are often used interchangeably, but they don't necessarily describe exactly the same thing. Understanding the difference is useful when specifying valves for mining applications. Knife Gate Valve A knife gate valve describes...
CMO A Series vs AB Series: Which Knife Gate Valve Should You Choose?
Choosing between different knife gate valve series can be confusing when the applications appear similar. CMO Africa's product range includes several valve series, each designed around different operating requirements. Two examples are the A Series and AB Series. A...
Knife Gate Valves for Mine Water: Where They Fit in a Water Management System
Water management is an essential part of mining operations. Mines may need to move and isolate: Process water Recovered water Mine water Wastewater Sludge Effluent The correct valve depends heavily on the characteristics of the water stream. Not All Mine Water Is the...
What Is a Knife Gate Valve Seat and Why Does It Matter?
The valve seat is one of the most important components affecting shut-off performance. Yet it is often overlooked when valves are being specified. What Does the Seat Do? The seat creates the sealing interface between the moving gate and the valve. Its design...
