Knife gate valves are engineered specifically for on-off and isolation operations in systems with a high dissolved solid particle. Knife gate valves are extremely useful when dealing with slurry, abrasive, corrosive, and viscous media. The valves have a low-pressure drop in the fully open position, are simple to operate, light in weight, and cost-effective. Knife gate valves are intended to work in the harshest conditions, with a sharpened blade to cut through heavy liquids.
