Isogate® Check Valves

About this product

Designed to prevent reverse flow in harsh, abrasive applications. Overview Our range of Isogate® check valves are designed for reverse flow prevention and quick changeover between duty and stand-by pumps in tough slurry applications. These valves are especially suited to mining and are often used within processes including fines removal, desliming, flotation, filtration and processing of coarse and fine particles. However, they can also be used in some industrial applications including chemical manufacturing, storage and sugar milling.
