The Isogate® WS series wafer style slurry knife gate valve incorporates Linatex® elastomer technology to provide reliable service in tough abrasive and corrosive slurry applications. The Isogate® WS series’ unique design provides reliable service together with ease of maintenance and cost effectiveness in a light weight, compact package. Using materials proven by Weir Minerals Linatex’s experience in abrasion and corrosion resistance, the Isogate® WS series wafer style slurry knife gate valve combines a low maintenance design with a wide range of available materials, making the valve suitable for a variety of applications. Key features/benefits Unibody design and rugged heavy duty construction ensures long valve life and greater reliability Flexible two-piece sleeve system allows valve to cycle in heavy slurries without sticking Sleeves are easily replaced without disassembling the valve Replaceable upper seal design is not only packingless, which eliminates the need for periodic adjustment, it is also a self-lubricating system and is rechargeable without valve disassembly (sizes 2” through 16”) Full port design reduces pressure drop and turbulence Open bottom allows for the purging of large solids and solids in high concentration Bi-directional shutoff Wafer style saves pipeline space Sleeves are available in a variety of materials to handle abrasion and chemical applications Flushing plate option allows for periodic cleaning of the lower discharge vent and allows flushing as needed Enclosed bronze stem bushing with a protected grease chamber means less operating force after long dormant periods
