Red Valve Co. offers the new Series DX slurry knife gate valve, designed especially for heavy slurry applications in the power and mining industries. When the Series DX valve opens, the reinforced elastomer sleeves seal against each other, and provide a 100-percent full port opening. The seats should 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. Each time the Series DX 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.
