In industries where failure is not an option, the choice of valve supplier matters just as much as the valve itself. Mining, slurry handling, wastewater treatment, and heavy industrial processing all demand equipment that can withstand extreme operating conditions without compromise.

That’s exactly why Fox Global continues to position itself as Australia’s leading supplier of Clarkson knife gate valves—delivering proven performance, technical expertise, and real-world reliability where it counts most.

Our latest supply into one of the world’s most demanding mining operations proves exactly that.

Delivering Reliability to Olympic Dam – A Real-World Case Study

Fox Global has recently completed the supply of 8-inch (200mm) Emerson Clarkson Fig 592 Stainless Steel Knife Gate Valves to a major mining contractor operating at the globally significant Olympic Dam site in South Australia.

This isn’t just another shipment—it’s a clear example of:

• Supplying into one of the harshest industrial environments on earth
• Meeting strict engineering and operational standards
• Delivering valves that must perform under constant stress

Olympic Dam is one of the largest known deposits of copper, uranium, gold, and silver in the world. Its operations involve abrasive slurries, aggressive chemicals, and continuous processing conditions that push equipment to its limits.

Only the most reliable valve solutions make the cut.

Why Clarkson Knife Gate Valves Lead the Industry

At the centre of this project is the globally respected Emerson Electric Clarkson Fig 592 knife gate valve.

Clarkson valves have built a reputation over decades for delivering:

• Exceptional durability
• Superior sealing performance
• Minimal maintenance requirements
• Long service life in abrasive environments

These aren’t theoretical benefits—they are proven in real mining operations across the globe.

What Makes the Clarkson Fig 592 So Effective?

The Clarkson Fig 592 is specifically engineered for the toughest slurry and process applications.

Key Performance Advantages

1. Designed for Abrasive Slurries

Mining slurry isn’t just liquid—it’s a mixture of solids, chemicals, and abrasive particles.

The Fig 592 handles this with:

• Heavy-duty 316 stainless steel construction
• Reinforced internal components
• Wear-resistant sealing surfaces

2. Integral RTFE Gate Scraper

One of the standout features is the built-in scraper system.

This:

• Cleans the gate during operation
• Prevents buildup
• Maintains sealing performance

This dramatically reduces maintenance requirements and extends valve life.

3. Superior Sealing Performance

With a precision-finished gate and engineered seat design, the Fig 592 delivers:

• Reliable shut-off
• Minimal leakage
• Consistent performance over time

4. Low Pressure Drop

The full-bore design allows:

• High flow rates
• Reduced turbulence
• Improved system efficiency

5. Built for Longevity

In mining environments, replacing valves frequently is not an option.

The Fig 592 offers:

• Long service intervals
• Reduced lifecycle costs
• Proven durability under continuous operation

Technical Specifications – Clarkson Fig 592

Fox Global supplied valves with the following key specs:

• Size: 8” (200mm)
• Material: 316 Stainless Steel
• Pressure Rating: 10 Bar (1000 kPa)
• Temperature Range: Up to 230°C (depending on seat)
• End Connections: DIN PN16 Flanges
• Design: Lugged, rising spindle, uni-directional
• Actuation: Double-acting pneumatic

Why Knife Gate Valves Are Critical in Mining

Knife gate valves are specifically designed for on-off isolation in difficult media.

What Makes Them Different?

Unlike ball or butterfly valves, knife gate valves:

• Cut through slurry and solids
• Prevent clogging
• Maintain sealing under heavy particulate loads

Where They Are Used

• Slurry transport lines
• Tailings systems
• Concentrate pipelines
• Effluent treatment systems

Without the right valve, these systems simply don’t function reliably.

Industries That Depend on Clarkson Knife Gate Valves

While mining is the most demanding, Clarkson valves are used across:

Mining

• Slurry lines
• Tailings handling
• Ore processing

Pulp & Paper

• Fibrous slurry control
• Process water systems

Wastewater & Effluent

• Sewage
• Sludge handling
• Treatment plants

Chemical Processing

• Corrosive liquids
• Abrasive media

Power Generation

• Fly ash systems
• Waste handling

Why Olympic Dam Demands the Best

Operations at Olympic Dam require equipment that can:

• Withstand abrasive wear
• Resist corrosion
• Operate continuously
• Deliver consistent sealing

A valve failure in this environment can:

• Halt production
• Damage equipment
• Create safety risks

When downtime can cost thousands per minute, reliability isn’t optional—it’s critical.
