Product Overview

Pneumatic Stainless Steel Ceramic Lined Knife Gate Valves are known as slurry gate valves. They have a simple structure and can cut off medium which contains solid particles and fibers. For very hard particles or serious erosive mediums, general metal seated knife gate valves will be washed out easily, making ceramic knife gate valves very suitable for mediums containing fibers and hard solid particles.
