Duplex Check Valves are primarily composed of duplex stainless steel, typically containing around 22% chromium, 5-7% nickel, and 3-5% molybdenum, along with small amounts of nitrogen and other elements. This composition provides excellent mechanical properties, including high tensile strength (up to 620 MPa) and enhanced resistance to stress corrosion cracking. The advantages of Duplex Check Valves include superior corrosion resistance, high strength, and the ability to withstand high pressures and temperatures. These features make them ideal for applications in the oil and gas, chemical, and marine industries, ensuring reliability and durability in harsh environments.
