Home > Super Duplex Steel > Super Duplex Needle Valve
Adrian Nickel Alloys stands out as a top-notch manufacturer and supplier of **Duplex Needle Valves** in Singapore, Pulau Ujong, delivering precision flow control solutions tailored for critical industrial applications. Crafted from premium duplex stainless steel, these valves boast a well-balanced ferritic-austenitic microstructure, which provides remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking, even in harsh, chloride-rich environments. They’re designed for accurate fluid flow regulation and come in a variety of sizes, pressure ratings, and end connections, all while adhering to international standards for durability, leak-tight performance, and longevity in demanding industries.
Typically, Duplex Needle Valves feature 22–25% chromium, 5–7% nickel, 3–4% molybdenum, and nitrogen, which together yield impressive tensile strength of around 620–800 MPa and yield strength close to 450–550 MPa, along with excellent toughness even in colder temperatures. The ferritic-austenitic microstructure guarantees mechanical stability, durability, and resistance to localized corrosion, especially under high-pressure and high-stress conditions.
