Nadia Tube Fittings is a reliable manufacturer and supplier of Duplex Manifold Valves based in Kuala Lumpur, Malaysia. We specialize in providing robust and high-performance solutions for fluid control systems. Our Duplex Manifold Valves are crafted from top-quality Duplex Stainless Steel (grades S31803 / S32205), which guarantees exceptional strength, durability, and resistance to stress corrosion cracking, pitting, and crevice corrosion. Designed with precision in mind, these valves ensure dependable shut-off, isolation, and regulation of fluids, even in the most demanding environments. They find extensive use in the oil & gas, petrochemical, power generation, and instrumentation sectors, delivering leak-proof performance and a long service life, even under aggressive and high-pressure conditions.
Our Duplex Manifold Valves are made from Duplex Stainless Steel, a unique material that combines the best features of austenitic and ferritic stainless steels. The commonly used grades, UNS S31803 and S32205, are enriched with chromium, nickel, and molybdenum, enhancing their corrosion resistance and strength. These valves boast high tensile strength, excellent toughness, and remarkable resistance to chloride-induced stress cracking. Their balanced microstructure ensures outstanding durability, making them ideal for high-temperature and high-pressure operations. The precise machining of the valve body and stem guarantees smooth operation, excellent sealing, and reliable performance in critical fluid control applications.
