UNS N08020 Check Valve
9 products found
An UNS N08020 check valve (Alloy 20) is an automatic non-return valve engineered for absolute backflow prevention in aggressive chemical media, specifically hot sulfuric acid. Fabricated from a specialized austenitic nickel-chromium-molybdenum alloy stabilized with niobium, the material resists sensitization and intergranular corrosion during welding. Driven by fluid kinetics, the internal disc or spring-loaded mechanism opens under forward pressure and snaps shut when flow decelerates, protecting upstream pumps. Alloy 20 metallurgy provides elite resistance to chloride-induced stress corrosion cracking, pitting, and crevice attacks. Chemical process engineers and refinery procurement networks can eliminate sulfuric acid corrosion and secure high-integrity non-return protection by importing certified UNS N08020 check valves directly from premier manufacturers in China via our advanced B2B commercial platform.
