Duplex Manifold Valves are manufactured from UNS S31803/S32205 duplex stainless steel. Typical chemical composition includes Chromium (21–23%), Nickel (4.5–6.5%), Molybdenum (2.5–3.5%), Nitrogen (0.08–0.20%), and Iron (balance). This composition ensures superior resistance to corrosion, high tensile and yield strength, and excellent toughness. Mechanically, these valves offer reliable performance under high pressure, temperature variations, and mechanical stress, maintaining leak-free operation and long-term durability in harsh industrial and marine environments where standard stainless steel valves may fail.
