从China供应商批量进口3 Pc Screwed Ball Valve

The 3 pc screwed ball valve from Cangzhou Hongfeng Precision Casting is a full bore, investment-cast valve designed for threaded installation in pipelines handling water, oil, and gas. Sizes range from 1/4 inch to 2 inch, with screwed ends conforming to ANSI B2.1, BS21, DIN259/2999, and JIS B0203 thread standards. The three-piece construction allows inline servicing without disturbing the pipeline, while the full bore profile maintains minimal flow resistance and pressure drop across the valve body.

Investment casting produces a dense, uniform wall structure that withstands cyclic stress and thermal shock better than sand-cast equivalents. The valve body, end caps, and ball are typically cast from carbon steel or stainless steel grades suited to the service fluid, with PTFE or similar fluoropolymer seats providing low-torque sealing and chemical compatibility. Standard industry practice for this class of valve includes blow-out proof stem design and ISO 5211 mounting pad options for automated actuation. Thread engagement length and pitch diameter tolerances follow the cited national standards to ensure interchangeability with BSP, NPT, and metric fittings.

These valves suit oil and gas field services, water treatment plants, HVAC balancing circuits, and general manufacturing process lines. Buyers include EPC contractors, industrial maintenance suppliers, and fluid equipment distributors who require ANSI-rated pressure classes with screwed rather than flanged end connections. Trade terms commonly offered include FOB Tianjin or Shanghai, with carton or wooden crate packaging standard for sea freight. Buyers should confirm material certificates, pressure test protocols, and seat leakage class with the supplier before placing an order, as these specifics are not stated in the listing data.

Cangzhou Hongfeng Precision Casting Co., Ltd operates from Niangniangmiao Industries Area in Yunhe District, Cangzhou, Hebei Province, a region with established foundry and metalworking supply chains serving northern China's valve and pipe-fitting sector. The supplier's tier is listed as imported and its trust tier as harbor, with a response rate of 0.00% and zero recorded average response hours. These signals indicate limited transactional history or engagement visibility on this platform, so buyers should treat direct communication as essential for due diligence.

The company name specifies precision casting as its core capability, suggesting in-house investment casting rather than outsourced rough castings. The listing does not state factory size, workforce, annual output, ISO certification status, or named clients, so claims about scale or accreditation cannot be verified from the source data. Buyers should request foundry qualifications, material mill test reports (MTRs), and third-party inspection records before committing to volume orders. The address places the supplier roughly 200 km from Tianjin Port, a logistical factor for FOB shipment planning.
