Isogate® WS

A wafer-style slurry knife gate valve designed for abrasive applications Using materials proven by our extensive experience and installation base in the slurry transport industry, Weir Minerals has developed the Isogate ® WS series wafer-style valve to deliver reliability and long term performance. Its unique design provides ease of maintenance and low overall ownership costs, delivering outstanding results. Continuous innovation in material, product design, engineering and manufacturing ensures that the Isogate ® knife gate valve range remains at the forefront of valve design. Minerals The Isogate ® WS series slurry knife gate valve is specifically designed for a wide range of tough, abrasive and corrosive applications. Open Position Only thick elastomer sleeves are in contact with slurry. No metal parts contact the fluid. Closed Position The gate is located in between thick elastomer sleeves, with full tight shut-off.

The purging of solids stops when the gate is in the full open or closed position. Flushing Plate Flushing plate option adds flexibilty to the standard open bottom. This option also allows for periodic cleaning of the lower discharge vent and can allow flushing as needed. Body Options Design features • Robust construction ensures long service life • Two-piece elastomer sleeve design protects flow areas against corrosion • Wafer body, narrow pattern minimises space requirement • Field replaceable thick elastomer sleeves are easily replaced without disassembling the valve • Sleeves incorporate Linatex ® rubber technology, plus a wide range of elastomer compounds are also available • Bi-directional 100% bubble tight shut-off • Packingless design - no gate or stem packing • Full port design reduces pressure drop and turbulence, minimising wear • Suitable for use in abrasive slurry services with high percentages of solids • Open bottom allows for the purging of large solids, and solids in high concentration • No seat cavities where solids can collect and cause gate interference • Yoke design allows fitting for all designed actuators • Flush control option allows for periodic cleaning of the lower discharge vent and allows flushing as needed Note 1: Dimensions provided are for information only. Certified drawings are recommended prior to construction. Note 2: Flanges are drilled and tapped to match ANSI B16.5 class 150#. Other flange options are available upon request. The Isogate ® WS series heavy duty knife gate valve features an adjustment free packingless upper seal which eliminates the need to constantly tighten the packing to eliminate leakage. The upper seal design also features a set of lubrication channels that contain a gate lubricant. A thin layer of the lubricant is placed on the gate on each and every cycle. This provides for smoother gate actuation and increased sleeve life. Fittings are accessible to recharge upper seal while in service. * sizes 50mm (2”) through 400mm (16”) Adjustment Free Packingless Upper Seal* lubricant channels sealing lips Note: The diagram above features the Linatex ® premium rubber sleeve option.
