Slurry Knife Gate Valve

Red Valve’s Series DX Slurry Knife Gate Valve is designed particularly for heavy slurry applications in the power and mining industries. When the valve opens, the reinforced elastomer sleeves seal against each other to provide a 100-percent full-port opening, minimizing turbulence and minimizing wear. The seats 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 valves, the valve prevents slurry buildup in the seat area, which might otherwise prohibit the valve from closing.
