Curtis Tube Fittings, located in Manila, Philippines, has earned a solid reputation as a reliable manufacturer and supplier of top-notch Super Duplex Manifold Valves. With a focus on precision engineering, outstanding performance, and impressive durability, Curtis designs valves that meet the rigorous demands of industries where corrosion resistance, strength, and reliability are paramount. Their Super Duplex Manifold Valves are crafted to meet international standards, guaranteeing leak-proof operation and efficient flow control even in high-pressure and aggressive environments. Curtis Tube Fittings caters to the oil and gas, chemical, marine, and industrial sectors, providing superior valve solutions that ensure consistent performance and operational safety.
These Super Duplex Manifold Valves are made from a high-performance duplex stainless steel alloy that includes 25–26% chromium, 6–7% nickel, 3–4% molybdenum, and nitrogen. This unique blend offers remarkable resistance to pitting, crevice, and stress corrosion cracking, along with impressive tensile strength (around 830–860 MPa) and yield strength (approximately 550–600 MPa). The excellent toughness and ductility of this material, combined with a balanced duplex microstructure, ensure reliable performance even under extreme temperatures, high-pressure conditions, and corrosive environments. This makes these valves perfect for critical applications where safety and long-lasting durability are a must.
