Square Knife Gate Valve

Square knife gate valves utilize a square-shaped gate to provide efficient flow control and reliable shutoff in applications involving viscous fluids, slurries, and solids. The square gate design offers a larger sealing area compared to traditional gate valves, resulting in enhanced sealing performance and reduced wear. Square knife gate valves are commonly employed in industries such as wastewater treatment, mining, and food processing, where handling thick or abrasive media requires robust and reliable valve solutions.
