Olwan Nickel Alloys stands out as a top manufacturer and supplier of high-performance Duplex Manifold Valves based in Amman, Jordan. We cater to industries that demand exceptional strength, reliability, and resistance to corrosion. With a solid engineering background and cutting-edge manufacturing techniques, our company creates manifold valves that guarantee precise flow control, even in the toughest conditions. We emphasize rigorous quality control, dimensional accuracy, and long-lasting durability, making our Duplex Manifold Valves a trusted choice for critical applications. Built to endure high pressures, corrosive substances, and varying temperatures, these valves find extensive use in marine, chemical, petrochemical, and offshore sectors both in Jordan and beyond.
Our Duplex Manifold Valves are crafted from duplex stainless steel, which consists of about 22% chromium, 5–7% nickel, 3% molybdenum, and a controlled amount of nitrogen. This unique dual-phase structure, combining ferrite and austenite, offers remarkable strength—almost double that of regular stainless steels—along with outstanding resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. These valves are known for their high toughness, fatigue resistance, and stability under high pressure and elevated temperatures. Their exceptional mechanical properties ensure reliable performance, a long service life, and consistent operation in demanding environments where corrosion resistance and structural integrity are crucial.
