AI-Powered supplier vetting

SummaryDanyang Feilun Gas Valve Co., Ltd. is identified as a manufacturer/factory in China, specializing in cylinder valves, CNG valves, cryogenic valves, gas regulators, and gas mixers. The supplier reports ISO 9000 and ISO 9001 certifications, more than 10 production lines, 41–50 quality-control staff, and 21–30 years of cumulative R&D engineer experience. Its description states that it possesses extensive testing, machining, extrusion, cleaning, drying, and air-testing equipment, and provides responsible after-sales service and customized products. However, many operational, R&D, overseas-service, sustainability, and quality-process fields are marked unknown. An SGS audit is recorded, but the stated audit evaluation result is not interpreted here as a demonstrated pass. One buyer and one trade transaction are listed, providing limited customer-case evidence.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and operates as a limited company in Jiangsu, China, within Industrial Equipment & Components. This supports direct manufacturing status rather than a trading-only profile.

CertificationsThe supplier reports holding ISO 9000 and ISO 9001 certifications. These are explicit certification records, although the provided slices do not include certificate numbers, scope, or current validity dates.

After-Sales capabilityThe company description explicitly states that it provides responsible and reliable after-sales service. However, specific service infrastructure such as overseas agents, branches, warehouses, and other delivery channels is marked unknown.

R&D capabilityThe supplier reports extensive manufacturing and testing equipment and 21–30 years of total R&D engineer experience. Specific evidence for new-product development, ODM, SDK support, private mold design, R&D audit documentation, or 3D design services is unavailable.

Production capacityProduction capability is supported by reported smelting, extrusion, CNC machining, testing, cleaning, drying, and air-testing equipment, more than 10 production lines, 41–50 quality-control staff, and stated gas-valve output. The supplier therefore demonstrates substantial stated manufacturing resources.

Customization capabilityThe company explicitly states that meeting customized-product requirements supports its sustainable development, which is direct evidence of customization support. Nevertheless, the specific technical scope of customization, including private molds and 3D design, is marked unknown.
