Series DX Slurry Knife gate valve is designed especially for heavy slurry applications in the power and mining industries. When it opens, reinforced elastomer sleeves 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 from coming in contact with the process. When the valve is closed, the sleeves provide a drop-tight seal. It also provides drop-tight shut-off in both directions.
