Wai Nickel Alloys, a well-respected manufacturer and supplier located in Naypyidaw, Myanmar, specializes in top-notch Duplex Steel Ball Valves that are built to perform exceptionally well in tough industrial settings. These valves are crafted with precision to ensure smooth operation, reliable sealing, and a long lifespan, even when faced with high pressure and temperature. Made from high-quality Duplex Steel, they resist pitting, crevice corrosion, and stress corrosion cracking. Duplex Ball Valves are perfect for managing the flow of liquids and gases in various applications, including marine, chemical, oil & gas, and desalination.
Duplex Steel Ball Valves are made up of Chromium (21–23%), Nickel (4.5–6.5%), Molybdenum (2.5–3.5%), and a balanced amount of Iron, along with small traces of Nitrogen, Manganese, and Silicon. Their duplex microstructure gives them impressive tensile strength (700–900 MPa) and yield strength (~450 MPa), all while ensuring excellent toughness and ductility. These valves boast outstanding corrosion resistance in environments rich in chlorides and acids, along with remarkable oxidation resistance and dimensional stability across varying temperatures. Their robust mechanical strength, paired with resistance to stress and erosion, makes them perfect for high-pressure fluid control systems.
