Import Bs1868 Check Valve — Buy in wholesale FOB from Supplier in China

The BS1868 check valve from Wenzhou Domos Fluid Equipment Co., Ltd is a bolted-bonnet, full-port check valve built to BS 1868 and API 6D design standards with pressure-sealed bonnet construction. It covers nominal sizes from 2 to 48 inches (DN50 to DN800) and pressure classes from 150 LB to 2500 LB (PN16 to PN420), with end connections in RF flange, wafer, and butt-welded configurations. Face-to-face dimensions follow ASME B16.10, flanged ends comply with ASME B16.5 (RF and RTJ), and butt-weld ends with ASME B16.25. The valve operates across temperatures from -196°C to +573°C and is tested to API 598 with NACE MR-0175 and MR-0103 compliance available.

Body materials span carbon steel, stainless steel, alloy steel, and duplex grades including WCB, LCB, LCC, WCC, WC5, C5, WC6, WC9, WC11, CF8, CF8M, CF3, CF3M, CD-4MCU, and SS2205. Forged options in NPS 2 and above include A105, A182 F304, F304L, F316, F316L, F51, F53, A350 LF2, LF3, LF5, and F904. Exotic alloys such as Monel, Inconel, Hastelloy, copper, and bronze are also offered. The valve is manufactured in piston, swing, lift, dual-plate wafer, and single-plate wafer configurations to suit different flow regimes and installation constraints.

This valve serves oil and gas production, petrochemical refining, power generation, and pipeline transmission where backflow prevention protects pumps and compressors. Buyers include EPC contractors, plant operators, and valve stockists who require API 6D or BS 1868 compliance for project specifications. The supplier lists an HS code of 84813000 for customs classification. Importers should confirm material certificates, pressure test reports, and NACE compliance documentation before shipment, and verify whether the specific alloy grade and end connection match their piping specification.

Wenzhou Domos Fluid Equipment Co., Ltd is located in Heyi Industrial Zone, Oubei, Yongjia, Wenzhou, Zhejiang Province, China, postal code 325105. The company operates from the Wenzhou valve manufacturing cluster, a region with extensive supply chains for castings, forgings, and valve machining. The supplier holds a harbor trust tier on the platform. The response rate is shown as 0.00 percent with zero average response hours, which suggests either new listing activity or incomplete engagement metrics. Buyers should initiate direct contact to assess current responsiveness and sales support capabilities.

The listing focuses on API and BS standard check valves with broad material and configuration flexibility. No specific factory size, annual output, certification body registrations, or named client projects are stated. The product range emphasises forged and cast steel construction across standard and exotic alloys, with design options for high-pressure and corrosive service. Importers are advised to request a factory audit, quality system documentation, and reference projects before committing to large orders, given the limited verification signals available.
