Duplex Stainless Steel Check Valve | Dual Plate Check Valve Manufacturer | TVCCL, TAIWAN VALVE

Manufacturer of check valves. Duplex Stainless Steel Check Valve - The "Duplex stainless steels" are a family of stainless steels. These are called duplex (or austenitic-ferritic) grades because their metallurgical structure consists of two phases, austenite (face-centered cubic lattice) and ferrite (body centered cubic lattice) in roughly equal proportions. Generally a small amount is not less than 30%. Due to the presence of ferrite and austenite in the duplex stainless steel. Therefore, it has the advantages of higher strength of ferritic stainless steel, resistance to chloride stress corrosion, and excellent toughness of austenitic stainless steel. Duplex stainless steel is more resistant to corrosion than the most common stainless steel valves, CF8 and CF8M. Duplex stainless steel valves are widely used in various industries such as chemical industry, seawater desalination, shipbuilding industry, petrochemical industry, oil and gas because of their extremely corrosion resistance and high strength.. Dual plate check valve manufacturer from Taiwan. Check valve supplies for over 20 years, 97% customer repurchase rate, ERP and CRM systems implemented with ISO manufacturing process. Available in a variety of valve materials, each dual plate check valve is inspected to reduce the risk of non-conformance.
