Gabriel Tube Fittings, based in Cairo, Egypt, stands out as a top manufacturer and supplier known for its high-quality **Super Duplex Check Valves**. These valves are crafted for exceptional performance and reliability, especially in tough applications. They’re specifically designed to prevent backflow and ensure a smooth, one-way flow in pipelines that deal with corrosive fluids or gases. With a strong emphasis on durability, precision, and leak-free operation, Gabriel Tube Fittings ensures that their products meet international quality standards. Their Super Duplex Check Valves are particularly resistant to corrosion, pitting, and stress cracking, making them perfect for critical industrial settings.
These valves are made up of about 25% chromium, 7% nickel, and 3–4% molybdenum, along with nitrogen, all of which boost their corrosion resistance and mechanical properties. The unique dual-phase austenitic-ferritic structure gives them impressive toughness and strength, boasting a typical tensile strength of 800–900 MPa and a yield strength of around 550 MPa. They also show remarkable resistance to chloride stress corrosion cracking, crevice corrosion, and erosion, even in high-pressure and high-temperature situations.
