Knife gate valves are designed for slurries, thick fluids, and materials with solid particles. Ultravalves Automation offers strong and durable knife gate valves with a sharp-edged gate that cuts through media to prevent clogging. Ideal for mining, wastewater treatment, pulp & paper, and chemical plants, these valves offer reliable isolation and smooth operation. Available in wafer and lugged types, they are built from corrosion-resistant materials for long-term performance. Our knife gate valves deliver tight shut-off, low maintenance, and excellent durability in harsh industrial conditions.
