FAQs - Knife Edge Gate Valve
A 20" Knife Edge Gate Valve is a large-diameter industrial valve with a sharp-edged gate designed primarily for isolating and controlling slurries, powders, viscous fluids, and media containing suspended solids.
They are commonly used in mining, cement, power, pulp and paper, wastewater treatment, chemical processing, steel, sugar, and slurry handling applications.
Its sharp-edged gate can cut through solids and thick media while providing effective pipeline isolation.
Yes. Knife Edge Gate Valves are particularly suitable for slurry applications because the gate can pass through media containing suspended solids.
Depending on the application, they can be manufactured with materials such as cast iron, ductile iron, carbon steel, stainless steel, and other suitable alloys.
