Industry Applications
-
Mining
Essential for handling abrasive slurries, mine tailings, and ore mixtures. The sharp knife-edge easily cuts through heavy solid-liquid media to ensure a reliable shut-off. -
Wastewater Treatment
Used to isolate pipelines carrying raw sewage, thick sludge, and industrial effluents. The non-clogging design ensures precise flow control for heavy waste media. -
Pulp & Paper
Perfectly suited for controlling thick paper stock and recycled fibers. The valve slices smoothly through fibrous media without jamming during operation. -
Power Generation
Widely utilized to control bottom ash slurries and cooling water discharge. It provides excellent isolation for highly viscous and abrasive power plant systems. -
Chemical Industry
Reliable for regulating the flow of viscous chemicals, polymer slurries, and crystalline liquids. The robust sealing prevents leakage when handling complex solid-liquid mixtures.
