SS 316 Butterfly Valve

An SS 316 butterfly valve is a compact quarter-turn rotary valve engineered with a disc, stem, and body cast from molybdenum-bearing austenitic stainless steel (CF8M) to provide superior corrosion resistance in aggressive fluid environments. The addition of molybdenum within the SS 316 matrix drastically enhances structural resistance against chloride-induced pitting, crevice corrosion, and chemical degradation, outperforming standard 304 stainless steel. Operating via a disc that rotates 90 degrees, this valve delivers rapid isolation and macro-throttling within a lightweight wafer, lug, or flanged body profile. Unlike cast iron or carbon steel valves that risk body rusting, disc damage, and stem binding if their internal coatings degrade, the inherent passivation layer of SS 316 ensures smooth operation without relying on external coatings. Offshore platform contractors and chemical processing engineers can eliminate chloride pitting and secure long-term system reliability by importing certified SS 316 butterfly valves directly from specialized manufacturers in China via our advanced B2B commercial platform.
