Knife Gate Valve is designed particularly for heavy slurry application in the power and mining industries. When the valve opens, the reinforced elastomer sleeve seal against each other to provide a 100% full-port opening, minimizing turbulence and minimizing wear. The seat isolate and protect all metal parts of the valve from coming in contact with the process. When the valve is closed, the sleeves provide a drop-tight seal. Another unique feature to this valve is its ability to provide drop tight shut-off in both directions. Each time the valve strokes, it is designed to discharge a small amount of slurry out of the valve, keeping the gate path and seat area clear of entrapped particulates. Unlike traditional knife gate valve, the valve prevent slurry buildup in the seat area, which might otherwise prohibit the valve from closing.
