Import Ball Valve Api6d — Buy in Bulk from Supplier in China

Jinnousen Technology Development Co., Ltd. manufactures API 6D ball valves in forged or cast carbon steel and stainless steel, sized from 2 inches to 42 inches nominal diameter for pipeline and process isolation duty. API 6D governs pipeline valves for the petroleum and natural gas industries, covering design, materials, face-to-face dimensions, testing, and documentation requirements. The valves feature a fire-safe design intended to maintain pressure-boundary integrity during external fire exposure, though the source does not specify whether this is achieved through graphite packing, metal-to-metal secondary seats, or other means. Buyers should request the specific fire-test certificate, preferably to API 6FA or ISO 10497, with the test pressure and duration stated.

Material options span cast carbon steel (likely ASTM A216 WCB), forged carbon steel (ASTM A105), and cast or forged stainless steel (ASTM A351 CF8M or ASTM A182 F316). The source does not state pressure class ratings, but API 6D valves are commonly offered in Class 150 through Class 2500 per ASME B16.34. Body construction may be two-piece split body, three-piece, or fully welded forged body for higher pressure and larger bore. Seat design is critical: the source mentions fire-safe construction but does not specify whether seats are soft-seated (PTFE or similar with metal backup) or metal-seated; this distinction governs suitability for abrasive or high-temperature media.

These valves target oil and gas transmission pipelines, downstream refining, chemical processing plants, and water treatment facilities requiring standardised, traceable valve procurement. The API 6D monogram is often a contractual requirement in upstream projects, so buyers should verify that Jinnousen Technology Development Co., Ltd. holds current API 6D monogram licence and that the specific valve serial numbers will carry the monogram and API 6D nameplate. Trade terms offered are FOB and CIF, yet port, lead time, and exact MOQ are not stated and must be confirmed directly with the supplier.

Jinnousen Technology Development Co., Ltd. is registered at No.67 Zhoujiazhuang Xincun, Shibalidian Town, Chaoyang District, Beijing 100023, China. The supplier holds imported-tier status with a harbor trust tier, reflecting basic marketplace registration rather than verified manufacturing depth. The response rate stands at 0.00 percent with zero average response hours, indicating no platform-mediated buyer engagement to date. This absence of response data places the burden on buyers to establish direct communication, preferably by visiting the Beijing address or engaging through verified trade channels before transferring funds.

The company presents itself as a manufacturer of API 6D ball valves for oil, gas, chemical, and water sectors, emphasising forged and cast steel construction across a broad 2-inch to 42-inch size range. No information is provided about factory location (whether in Beijing or elsewhere), production floor area, number of employees, annual output, years in operation, or reference projects. The source mentions ISO and CE certifications without numbers, and does not confirm current API 6D monogram licence, which is essential for credibility in petroleum pipeline supply. Buyers should conduct due diligence including factory audit, quality system review, and witness of hydrostatic testing before relying on this supplier for critical service.
