Technical Specifications
Key Features & Applications
Designed for use in corrosive process applications that may require more protection than ordinary stainless steel can offer, the Duplex Steel Ball Valve has been designed for durability, toughness, and excellent corrosion resistance while being quite lightweight. The unique microstructure of duplex steel makes it more resistant to pitting, crevice, and stress corrosion cracking caused by chlorides. The Duplex Steel Ball Valve is ideal for use in offshore installations, seawater service, chemical plants, and marine environments. African Valve is the leading manufacturer of Duplex Steel Ball Valves in Africa, offering these valves in different pressure ratings, end connections, and configurations throughout Nigeria, Egypt, South Africa, Kenya, Ghana, and other African countries, along with international export destinations. The Duplex Stainless Steel Ball Valve is recommended in instances where mechanical strength and corrosion resistance are both critical considerations. Unlike ordinary stainless steels like SS304 and SS316, the duplex stainless steel provides enhanced yield strength along with excellent chloride resistance. It is thus well suited for use in saline water, offshore, fertilizer, and desalination plants. The valve is thus designed to prolong service life while minimizing maintenance work in corrosive applications.. Operation of the valve is done by 90 degrees turning of precisely machined ball to ensure full opening or closing of flow. With the help of handle or actuator rotating of the stem, the bore either opens or seals to metal or resilient seats and ensures reliable sealing at different pressure ratings. The Duplex Steel Ball Valves can be available as Floating or Trunnion Mount depending upon the size and pressure ratings of valves. There are additional accessories like blow-out proof stem, anti-static, fire safe and ISO 5211 mounting pads. The valve is manufactured using: Duplex Stainless Steel ASTM A182 F51 Duplex Stainless Steel ASTM A995 Grade 4A UNS S31803 UNS S32205 Construction features include: Duplex stainless steel body and trim Blow-out Proof Stem Fire-safe Construction Anti-static Device Soft Seat or Metal Seat options Full Bore and Reduced Bore designs Flanged, Threaded, Socket Weld, and Butt Weld end connections Lever, Gear, Pneumatic, Electric, and Hydraulic operation Size Range: DN15 to DN600 (½" to 24") Pressure Ratings: Class 150 to Class 2500 Design Standards: API 6D, API 608, ASME B16.34, ISO 17292 Testing Standard: API 598 End Connections: Flanged, Butt Weld, Socket Weld, Threaded Operation: Lever, Gear, Pneumatic, Electric, Hydraulic Duplex Steel Ball Valves are widely used in: Offshore Oil & Gas Desalination Plants Marine Systems Chemical Processing Petrochemical Plants Fertilizer Industry Water Treatment Pulp & Paper Power Generation Excellent resistance to pitting and crevice corrosion Higher mechanical strength than conventional stainless steel Suitable for chloride-rich and seawater applications Available in floating and trunnion-mounted designs Compatible with manual and automated operation Manufactured according to international engineering standards African Valve manufactures Duplex Steel Ball Valves in accordance with international engineering standards and project specifications. Every valve undergoes dimensional inspection, hydrostatic shell testing, seat leakage testing, operational testing, and final quality verification before dispatch. Material Test Certificates (MTC), PMI reports, NDT reports, and inspection documentation are available to support engineering approval and project compliance. African Valve supplies Duplex Steel Ball Valves to offshore, marine, desalination, chemical processing, and industrial projects throughout Nigeria, Egypt, South Africa, Kenya, Ghana, and other African countries, as well as international export markets. Valves are available in multiple pressure classes, end connections, material grades, and actuation systems to meet demanding corrosive service applications.Duplex Steel Ball Valve Manufacturer in Africa
