Clarkson Knife Gate Valves

Clarkson slurry valves are among the most reliable and one of the most technologically advanced slurry valves on the market. Clarkson valves are used for severe applications such as line blanking, double block and bleed, and general isolation. Utilizing dual elastomer seats, Clarkson products offer bi-directional, self-cleaning, and self-purging capabilities to handle heavy slurries including saturated and viscous media, which cause severe scaling in the pipeline. Clarkson valves provide solutions for applications where downstream leakage cannot be tolerated and is often required in mining, power, and process industries.
