KNIFE GATE VALVE
Series DX slurry knife gate valve, for heavy slurry applications in the power and mining industries, have reinforced elastomer sleeves that, when open, seal against each other and provide a 100% full port opening, minimizing turbulence which in turn minimizes 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. The valve also provides 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.
