Import Ball Valves-Aluminum Compresed Pipe — Buy in wholesale FOB from Supplier in China

These ball valves from Guangdong Foster Fluid Technology in Foshan, Guangdong, are engineered for integration with aluminium compressed air piping systems under the supplier's FST Pipe product line. The valves are designed for quick-connect or threaded installation in blue aluminium alloy pipe networks rated for compressed air and inert gas service. Standard aluminium compressed air piping operates at pressures up to 16 bar, with typical pipe diameters ranging from 20 mm to 200 mm outer diameter, so valve pressure rating and connection geometry must match the specific FST pipe series. The ball valve body is typically aluminium alloy or brass with nickel plating for corrosion resistance in compressor room environments, though exact body material requires confirmation from the supplier.

The aluminium pipe system uses anodised or powder-coated aluminium alloy extrusions with push-fit or flange connections, and ball valves must provide compatible sealing without galvanic corrosion at dissimilar metal junctions. Ball seats are typically PTFE or modified PTFE for dry air compatibility, with Buna-N or Viton O-rings where elastomeric seals are present. The 10-year warranty referenced by the supplier suggests confidence in fatigue resistance and seal longevity under cyclic compressor loading. Buyers should confirm whether the valve is full-port or reduced-port, as this affects pressure drop in high-flow blowgun or pneumatic tool circuits, and whether the valve includes a locking handle for safety isolation during maintenance.

Primary applications include compressed air distribution in automotive workshops, textile factories, and food packaging lines where aluminium piping replaces galvanised steel for lighter weight and corrosion resistance. The valves serve as isolation points for compressor branches, filter-regulator-lubricator stations, and dead-leg elimination. For buyers importing from Foshan, Guangzhou Port and Shenzhen Port are the nearest major export gateways, with the supplier offering OEM branding under buyer labels. Trade terms, MOQ, and lead time require direct negotiation, as the source description emphasises factory-direct sourcing without stating fixed quantities or standard delivery schedules.

Guangdong Foster Fluid Technology Co., Ltd. is located at No. 3, Huafu North Road, Chancheng District, Foshan, Guangdong Province, in China's Pearl River Delta manufacturing corridor. The company operates under the FST Pipe brand and positions itself as a manufacturer of aluminium compressed air piping, stainless steel piping, and associated fittings including valves, flanges, forgings, fasteners, strainers, gaskets, elbows, sockets, reducers, and quick-drop connections. The supplier holds a Harbor trust tier, though response metrics show zero recorded activity. No employee count, annual revenue, factory floor area, or years of establishment are stated in the source data.

The supplier offers both FST-branded and OEM-branded products, indicating manufacturing capability for private-label contracts. Contact channels include telephone, fax, email, Skype, QQ, WeChat, and WhatsApp, suggesting established export operations. The source description references a 10-year warranty and global product utilisation, though no specific certifications, audit records, or client references are provided. Buyers should independently verify manufacturing credentials, request factory inspection reports, and confirm that the aluminium pipe and valve assemblies meet local pressure equipment directives before specifying in projects.
