Import Ball Valves — Buy in Bulk from Supplier in China

China Jiangpai Valve Co., Ltd. manufactures one-piece ball valves in sizes from 1/4 inch to 2 inches, rated for pressures between 150 and 900 lbs. These are reduced-bore or full-port designs (confirm with the supplier) with threaded or socket-weld end connections typical of this valve category. The pressure rating spans ANSI Class 150 through Class 900 equivalent, indicating suitability for medium to high-pressure pipelines in oil and gas, petrochemical, and general industrial service.

The body material is typically carbon steel ASTM A216 WCB or stainless steel ASTM A351 CF8M for standard industrial ball valves in this pressure class, though the exact grade should be confirmed with China Jiangpai Valve Co., Ltd. Seats are typically PTFE or RPTFE for chemical resistance and low-torque operation; seals may be Viton or similar fluorocarbon elastomers for hydrocarbon service. The one-piece body design eliminates leak paths compared with two- or three-piece construction but does not allow inline maintenance of the ball and seat assembly.

These valves suit water, oil, gas, and non-corrosive chemical applications where on/off service is required rather than throttling. Typical buyers include pipeline contractors, OEM equipment manufacturers, and MRO distributors sourcing for industrial plants. Importers should verify end-connection standards (BSP, NPT, or socket weld per ASME B16.11), bore configuration, and material test certificates before confirming orders.

China Jiangpai Valve Co., Ltd. is headquartered at 5th Floor of No.3326, Jichang Road, Wenzhou, Zhejiang Province, 325000, China. Wenzhou is a recognised cluster for valve and pump manufacturing in China, with a dense supply chain of foundries, machining shops, and testing facilities. The supplier is listed as an imported-tier vendor with harbor trust status; the response rate shows 0.00% with zero average response hours, meaning no response data is available to buyers at this stage. No information about factory size, workforce, revenue, or year of establishment is provided in the listing.

The company profile does not disclose certifications, export markets, or client references. Buyers should conduct independent verification of manufacturing capability, quality system registration (ISO 9001, API Q1), and product testing capacity before placing orders. The listing focuses on a narrow product line, one-piece ball valves in standard industrial sizes, which may indicate specialised production or a trading operation sourcing from Wenzhou-area workshops.
