Series DX is designed for heavy slurry applications in the power and mining industries. When the slurry knife-gate valve opens, the reinforced elastomer sleeves seal against each other and provide a 100 percent full-port opening, minimizing turbulence and, in turn, 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 provides drop-tight shutoff 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.
