Knife Gate Valve

Knife Gate Valve

Specifically designed to handle tough, abrasive, and viscous media in industries where conventional valves struggle. Its sharp-edged blade slices through thick slurry, pulp, or solids-laden fluids with minimal flow obstruction. Featuring a compact body and unidirectional or bidirectional sealing options, this valve is ideal for low-pressure, high-solid-content flow applications in harsh environments. Available in various actuation types and body materials to suit different process requirements.

    Benefits

    • Non-Clogging Performance – The sharp gate cuts through solids, preventing jamming and reducing downtime


    • Compact and Lightweight – Easy to install in confined spaces, especially in retrofit projects


    • Reliable Shutoff – Designed for tight sealing even with challenging media


    • Low Maintenance – Simple structure with minimal wear parts


    • Wide Range of Sizes and Materials – Suitable for many industrial sectors and fluid types
