Import Flange Type Turbine-Driven Butterfly Valve — Buy in Bulk from Supplier in China

The flange type turbine-driven butterfly valve is a quarter-turn flow control device designed for industrial fluid systems requiring precise throttling or isolation. It features a disc mounted on a rotating shaft, actuated by a turbine gear mechanism for high-torque applications, and is compatible with flanged pipe connections per ANSI B16.5 standards. The valve body is constructed from ductile iron or carbon steel, with sealing surfaces typically made of EPDM or PTFE to handle media such as water, air, acidic solutions, and LPG.

Typical operating pressure ratings range from PN10 to PN16, with temperature limits up to 120°C for EPDM seals and 200°C for PTFE. The turbine actuator allows manual or automated operation and is suited for valves larger than 200mm diameter where handwheel operation is impractical. The disc may be lined with elastomers or hardened stainless steel for abrasive slurries, though exact lining material is not specified in the source. Standard compliance follows ISO 5208 for leakage rates and API 609 for design.

This valve is commonly purchased by chemical processing plants, water treatment facilities, and oil and gas distributors requiring reliable shut-off under moderate pressure. Buyers typically order in batches of 10 to 50 units, with packaging in wooden crates and export-ready labeling. Lead times are not confirmed; buyers should request written confirmation of production scheduling. Incoterms such as FOB Dalian or CIF Rotterdam are standard, but must be verified directly with the supplier.

Jilin Senfeng Pipe Co., Ltd. is based in Panshi, Jilin Province, China, and operates as a manufacturer of pipeline components including valves and fittings. The supplier has a harbor trust tier, indicating verified export experience, but no response rate or average reply time is available. The listing confirms production capability but provides no details on workforce size, annual output, or client references. No certifications such as ISO 9001 or API 6D are claimed.

The company's product focus appears limited to flanged valves and pipe accessories, with no indication of design engineering services or in-house testing labs. Buyers should treat this as a production-only supplier and request third-party inspection reports for critical applications. The absence of response metrics suggests limited post-sale communication infrastructure; direct contact via phone or email is advised before placing orders.
