Noah Tubefittings is a reputable manufacturer and supplier located in Kinshasa, Congo, specializing in high-quality **Duplex Manifold Valves** that are crafted for precision flow control, durability, and outstanding corrosion resistance in tough industrial settings. These valves are designed to isolate, regulate, and manage fluid flow in high-pressure and corrosive environments. Made from top-notch Duplex Stainless Steel, they offer remarkable mechanical strength, leak-proof performance, and a long lifespan. Noah Tubefittings guarantees that each Duplex Manifold Valve operates reliably and stably, making them perfect for critical instrumentation and process control tasks.
The composition of Duplex Manifold Valves primarily includes chromium (22%), nickel (5–6%), and molybdenum (3%), with nitrogen added to enhance mechanical strength and corrosion resistance. They boast a tensile strength of about 620 MPa and a yield strength of roughly 450 MPa. The dual-phase (austenitic-ferritic) structure provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, ensuring they perform consistently even in high-pressure and corrosive conditions.
