从India供应商批量进口A350 Lf2 Alloy Steel Gate Valve 5500

The A350 LF2 Alloy Steel Gate Valve 5500 is a forged alloy steel gate valve rated for pressures up to 5500 PSI, manufactured by SQK Valves Fittings & Automation Private Limited in India. It is constructed from A350 LF2 material, a low-carbon manganese steel with additions of nickel and vanadium that delivers notch toughness down to -50 degrees Celsius. The valve employs a wedge-type gate design with flanged end connections, available in nominal bore sizes from 2 inches to 12 inches. The 5500 PSI pressure class places this valve in the high-pressure category suitable for critical service applications.

A350 LF2 is a standard material grade under ASTM A350 for forged or rolled alloy steel flanges, fittings, valves and parts intended primarily for low-temperature service. The LF2 designation specifies a normalized and tempered or quenched and tempered condition with Charpy V-notch impact testing required at -50 degrees Fahrenheit. Typical chemical composition includes 0.30% maximum carbon, 0.60-1.35% manganese, 0.15-0.30% silicon, with residual nickel, chromium and molybdenum controlled for hardenability and toughness. The wedge gate in this design provides bi-directional sealing with metal-to-metal seating, standard for ANSI Class 900 and above high-pressure gate valves.

This valve serves petrochemical plants, oil and gas production facilities, power generation stations, water treatment infrastructure and heavy manufacturing where positive shutoff and minimal pressure drop are required. Buyers typically specify face-to-face dimensions per API 6D or ASME B16.10, end flange drilling per ASME B16.5, and testing per API 598. The supplier notes adherence to ISO standards, though buyers should request specific certificates of conformance. Packaging is arranged for secure transport; Incoterms FOB or CIF are mentioned. The actual MOQ, lead time and pricing are not stated and should be confirmed directly with SQK Valves Fittings & Automation Private Limited.
