Import Flangedbutt-Weld Ball Valve — Buy in Bulk from Supplier in China

The flanged butt-weld ball valve from Hebei Shengri Import & Export Co., Ltd. is designed for high-pressure fluid control in industrial systems, with nominal sizes ranging from 2 inches to 32 inches and pressure ratings from Class 150 to 1500 lb. The valve body is manufactured using materials including WCB, LCB, CF8, CF8M, CF3, CF3M, A105, and LF2, each selected for mechanical strength and corrosion resistance in demanding environments. These materials conform to ASTM A216 and A351 standards for castings, ensuring structural integrity under operational stress.

The flanged ends are machined to ASME B16.5 dimensional standards, allowing direct welding to pipeline systems without additional fittings. The ball seat is typically made of PTFE or RPTFE for low-friction sealing, with metal-to-metal seating available for high-temperature applications. These valves are not typically equipped with pneumatic or electric actuators unless specified separately, and are intended for manual or gear-operated actuation in fixed installations. The internal components are designed to withstand cyclic pressure surges common in oil and gas pipelines.

These valves are primarily purchased by contractors in oil and gas transmission, chemical processing plants, and power generation facilities where leak-tight isolation is critical. Buyers often require documentation of material test reports for each batch and proof of hydrostatic testing per API 598. Trade terms offered include FOB Qingdao and CIF destination ports, with minimum order quantities typically starting at one unit for standard sizes, though bulk orders may be negotiated. Packaging is in wooden crates with internal foam padding to prevent surface damage during transit.
