Hakan Nickel Alloys, based in Istanbul, Turkey, is a trusted manufacturer and supplier of Super Duplex Ball Valves, engineered for precision, reliability, and long-term durability. Designed for industries that demand both strength and corrosion resistance, these valves provide smooth operation and secure flow control in harsh environments. Manufactured to meet international standards, Super Duplex Ball Valves combine superior mechanical performance with exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. Ideal for oil and gas, chemical, marine, and power applications, Hakan Nickel Alloys ensures that each valve delivers consistent, dependable performance even under extreme conditions.
Super Duplex Ball Valves are made from high-quality Super Duplex Stainless Steel, typically S32750, containing chromium, nickel, molybdenum, and nitrogen. This dual-phase ferrite-austenite structure provides excellent corrosion resistance, high tensile and yield strength, and superior fatigue resistance. They maintain dimensional stability and mechanical integrity under high pressure, elevated temperatures, and chemically aggressive environments. Lightweight yet durable, these valves combine toughness with long-term reliability, ensuring leak-proof, precise flow control in pipelines, process systems, and critical industrial applications exposed to seawater, chemicals, and other harsh conditions.
