Knife gate valves are generally designed for on-off and isolation services in systems with a high suspended solids content. Knife gate valves are especially useful when dealing with slurry, viscous, corrosive, and abrasive 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 designed to work in the harshest environments, with a sharpened blade to cut through heavy liquids. They are useful in wastewater applications where corrosion is a major concern. To have a knife gate valve made of acid-proof stainless steel is advantageous because it is less susceptible to corrosion damage and thus requires less maintenance or even replacement. Knife gate valves are cost effective quick-acting valves for clean and dirty water low-pressure applications.
