Polyurethane, when used in immersion, exhibits wear resistance that is 8 times greater than carbide, 7 times that of vulcanized rubber, and 3 times that of ultra-polymer polyethylene. Its exceptional wear resistance to solid particles, combined with its elasticity and mechanical properties, allows it to absorb the impact of particles and minimize wear. By incorporating polyurethane into the design of valves, we significantly increase their lifespan. The Full PU Lined Slurry Knife Gate Valve is designed for bi-directional, tight on-off service in abrasive slurry applications. These valves feature a full polyurethane lining, with the wear-resistant material injected using a whole-mold process, ensuring all media are encased in the lining for comprehensive wear protection. This results in excellent wear life and 100% positive shutoff of abrasive slurry. These valves are particularly well-suited for mining applications.
