Red Valve”s Series DX slurry knife gate valve is a durable and user-friendly device designed for heavy slurry applications in the power and mining industries. When the Series DX valve opens, 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 in contact with the process. When the valve is closed, the sleeves provide a drop-tight seal. The valve is able 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, thus preventing slurry buildup in the seat area, which might otherwise prohibit the valve from closing.
