The CF8 Class 300 Metal Seat Wafer Spring Check Valve is a high-performance, single-plate valve designed for extreme industrial environments. The CF8 (304 Stainless Steel) body offers excellent corrosion resistance, while the metal-to-metal seat ensures durability in high-temperature or abrasive services where soft seats would fail. Its compact wafer design fits between flanges to save space and weight, with a spring-assisted closure that prevents water hammer and backflow.
