Mining and Minerals

Abrasive Media Handling

Mining operations often move large amounts of slurry, sand, and rock fragments. These materials can wear down equipment quickly. DN80 GGG40 knife gate valves help solve this problem. Their ductile iron bodies resist damage from sharp and gritty particles. The sharp-edged gate slices through thick slurries and blocks the flow when needed.

Operators in mining sites choose these valves for several reasons:

• DN80 GGG40 knife gate valves handle slurries with high solids content.
• The valves isolate abrasive media, preventing leaks and spills.
• When fully open, the valves allow fluids to flow with little pressure drop.

Pulp and Paper

Fiber and Pulp Flow

Pulp and paper mills move large amounts of fibrous materials mixed with water. These slurries can be thick and sticky. DN80 GGG40 knife gate valves help control this flow. The valves use a sharp, knife-edge wedge to cut through dense pulp and fibers. This action keeps the lines clear and moving. Operators rely on these valves to separate materials during pulping and papermaking. The valves handle both thin and thick slurries with ease.

The body of the valve uses ductile iron (GGG40). This material gives the valve strength and flexibility. It resists corrosion and wear from different pulp mixtures. The valves also withstand crushing pressures and abrasive materials, such as sand or silica, that often appear in pulp lines. With a temperature range from -10°C to +120°C, these valves work well in most pulp and paper environments.
