Import Ball Valve, Flange End Ball Valve. — Buy in Bulk from Supplier in China

Jilin Senfeng Pipe Co., Ltd. manufactures flanged-end ball valves sized from DN50 to DN200, designed to DIN EN 3357-1 standards with face-to-face dimensions conforming to DIN EN 588-1. The flange drilling follows BS EN 1092-2, allowing direct bolting to matching pipe flanges without adaptor sets. These valves are quarter-turn rotary devices with a spherical closure element that provides tight shut-off in oil and gas, water treatment, and chemical processing installations. The supplier is located on Fukang Road in Panshi, Jilin Province, and holds a harbor trust tier with no response-rate data recorded.

Body material is not explicitly stated but is typically carbon steel ASTM A216 WCB or stainless steel CF8/CF8M for flange-end ball valves in this pressure class and size range. The ball and seat materials, stem sealing configuration, and anti-static device presence are not detailed in the source and should be requested. DIN EN 3357-1 governs general requirements for industrial valves, while DIN EN 588-1 defines the short and long pattern face-to-face dimensions that ensure retrofit compatibility with existing pipeline spacing. Typical pressure ratings for this construction standard are PN16 or PN25, though the exact rating must be confirmed with Jilin Senfeng Pipe Co., Ltd.

Engineers and procurement teams in petrochemical refineries, municipal water boards, and power plants use these valves for on-off isolation and, in some configurations, throttling service. The flanged ends simplify maintenance by allowing full valve removal without cutting pipe, an advantage over welded-end designs. Buyers should confirm body-wall thickness against ASME B16.34 or EN 12516 if pressure-temperature ratings are critical, and request fire-safe certification to API 607 for hydrocarbon duty. The listing mentions ISO and SGS certificates without specifics, so valid scope and expiry dates should be verified directly with the supplier.

Jilin Senfeng Pipe Co., Ltd. is based at B-1, Jiancaijiayuan, Fukang Road, in Panshi, Jilin Province, northeastern China. The supplier holds a harbor trust tier, with a recorded response rate of 0.00 percent and zero average response hours. The listing positions the company as a manufacturer of flanged-end ball valves for industrial fluid control, but does not state year of establishment, factory size, number of employees, or production capacity. No specific ISO certificate numbers or SGS report references are provided, only generic mentions of certification availability.

The address in Panshi places the supplier within Jilin's industrial corridor, though buyers should conduct independent verification of manufacturing credentials through factory audit or video inspection, given the lack of response data. The listing does not indicate whether the company casts its own valve bodies or sources them, so in-house machining, assembly, and pressure-testing capabilities should be confirmed. Direct enquiry is necessary to clarify warranty terms, spare parts availability, and whether the company has supplied valves to projects requiring third-party inspection under EN 10204 3.1 or 3.2 certificates.
