These valves are made up of about 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, which together provide exceptional strength, corrosion resistance, and toughness. They boast nearly double the yield strength of standard austenitic stainless steels while still offering good ductility and fatigue resistance. With excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking, these valves are designed for smooth operation and precise control. Duplex Steel Manifold Valves ensure consistent performance even under high-pressure and high-temperature conditions, making them ideal for critical and complex systems.
