A 3-piece Hastelloy C22 butt welded ball valve with lever PN40 is a high-performance isolation valve designed for extreme corrosion resistance in aggressive chemical environments. Hastelloy C22 (UNS N06022) is a nickel-chromium-molybdenum alloy with added tungsten, offering superior resistance to pitting, crevice corrosion, and stress corrosion cracking in oxidizing and reducing conditions . The 3-piece construction allows in-line maintenance without removing the entire valve from the pipeline . Butt weld ends provide permanent, leak-proof connections ideal for high-integrity systems. Rated PN40 (40 bar / 580 psi) and operated by a lever for quick quarter-turn actuation, these valves are widely used in chemical processing, pharmaceutical, petrochemical, and marine applications .
