The Stainless Steel 304 Metal-Seated Knife Gate Valve is engineered for high-temperature and abrasive service where resilient seats fail. The SS304 (CF8) body and gate provide exceptional corrosion resistance against harsh chemicals and oxidized media. Featuring a metal-to-metal seat, it excels in handling hot ash, pulp, and dry solids. The beveled gate "knifes" through thick slurries, ensuring reliable manual isolation in mining, power, and chemical processing plants.
