The Series DX slurry knife gate valve is designed especially for heavy slurry applications in the power and mining industries. When the valve opens, the reinforced elastomer sleeves seal against each other and provide a 100 percent full port opening, minimizing turbulence which in turn minimizes wear. The seats isolate and protect all metal parts of the valve from coming into contact with the process. When the valve is closed, the sleeves provide a drop-tight seal, and the valve can provide drop-tight shut-off in both directions.

Editor’s Note
Each time the valve strokes, it discharges a small amount of slurry to keep the gate path and seat area clear of entrapped particulates.
