'carnegie, pa (may 1, 2009) - red valve company, inc. is pleased to announce the introduction of their newest product, the series dx slurry knife gate valve. the series dx slurry knife gate valve is recognized as the most durable and user-friendly knife gate valve. it is 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% 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. another unique feature to this valve is its ability to provide drop tight shut-off in both directions.'查看更多
