Frequently Ask Questions
A Slurry Knife Gate Valve is designed specifically for isolating abrasive slurry and solid-containing fluids. Its sharp-edged gate helps cut through thick media for reliable shut-off.
A Slurry Knife Gate Valve is specifically configured for abrasive and high-solids media, generally with enhanced wear resistance and suitable sealing materials.
Consider slurry concentration, particle size, abrasiveness, pressure, temperature, valve size, seat material, and required actuator type.
The knife gate moves vertically through the media, cutting through solids and creating an open or closed flow passage.
Alis Valves manufactures and supplies Slurry Knife Gate Valves for mining, mineral processing, wastewater, cement, and other demanding industrial applications.
