Frequently used within mining, Isogate® wafer-style knife gate valves are lightweight and ideal for low-pressure slurry transport duties, classification, tailings, filtration and dredging.
Thanks to their great abrasion-resistance and reliability, they are frequently used for abrasive slurry services that contain a high percentage of solids.
Compared to other types of valves, our Isogate® wafer-style knife gate valves offer the following benefits:
Isogate® valves can also be integrated with our Accumin® automatic lubricators to maximise sleeve life and valve performance.
