Knife gate valves are specifically designed for handling slurry, viscous, or abrasive fluids. Their sharp, knife-like gate slices through thick media and provides a secure shutoff, making them essential in pulp and paper, mining, and wastewater industries. These valves are built to perform in tough conditions where conventional valves might clog or fail.

Their unidirectional or bidirectional sealing ensures versatility in flow direction, and the minimal pressure drop when open maintains flow efficiency. Knife gate valves come in different materials and actuation types, offering manual, pneumatic, and electric options for operational flexibility.
