从China供应商批量进口3-Pc Body Floating Ball Valve

The 3-piece body floating ball valve from Btl Valve Group is manufactured in Wenzhou, Zhejiang Province, designed to BS 5351 with butt welding connecting ends conforming to ASME B16.25. The three-piece construction permits inline maintenance without removing the valve from the pipeline, as the central body section containing the ball and seats can be detached while end caps remain welded in place. The floating ball design relies on downstream seat compression against the ball for primary sealing, with upstream seat providing secondary sealing under pressure. Wall thickness conforms to ASME B16.34, providing pressure-temperature ratings for carbon steel, stainless steel, or alloy body materials. The valve handles water, oil, gas, and compatible chemical media across industrial process lines.

Body material selection typically encompasses ASTM A216 WCB (carbon steel), ASTM A351 CF8M (316 stainless steel), or ASTM A351 CF8 (304 stainless steel), with trim materials matched for corrosion resistance and wear properties. Ball and stem construction is commonly 316 stainless steel with RPTFE (reinforced polytetrafluoroethylene) or metal seat inserts depending on temperature and pressure requirements. The floating ball configuration suits medium-pressure applications where full bore or reduced bore flow characteristics are acceptable; the ball is not trunnion-supported, so line pressure forces the downstream seat into contact. Blowout-proof stem design, anti-static device, and locking provision are common optional features in this valve category. Surface finish and casting integrity affect pressure retention and cycle life, with investment casting or forged construction typical for quality-tier products.

Primary applications span water treatment distribution, oil and gas pipeline isolation, chemical process plant switching, and general industrial fluid control. Buyers include engineering contractors, process plant operators, municipal water authorities, and OEM equipment packagers. The Wenzhou location positions Btl Valve Group within China's valve manufacturing cluster, with established supply chains for castings, forgings, and machining services. For importers, confirming material certificates (MTC per EN 10204 3.1 or 3.2), pressure testing protocol (hydrostatic shell and seat test, pneumatic test if required), and NDE (non-destructive examination) scope is essential. Specific alloy grades, seat material specifications, and end connection details beyond the stated butt weld configuration require direct enquiry to Btl Valve Group.

Btl Valve Group is located at Btl Industrial Park, Sanqiao Industry Zone, Wenzhou 325000, Zhejiang Province, China. The supplier operates within the imported tier with a harbor trust designation. The response rate is recorded at 0.00 percent and average response hours at zero, which indicates that direct outreach is necessary to assess communication responsiveness and technical support capability. The industrial park address suggests dedicated manufacturing or assembly facilities, though the extent of vertical integration (in-house casting, forging, machining, versus outsourced processing) is not disclosed in available data. No information is provided on workforce size, annual production volume, export markets served, or specific industry certifications held.

The listing describes product conformance to recognised international standards but does not present supplier-specific credentials such as ISO 9001 or ISO 15848 certification, API monogram licence, or specific end-user project references. Wenzhou's valve industry reputation spans from commodity producers to quality-focused manufacturers with full material traceability and testing documentation. Importers should request current quality management system certificates, sample MTCs (material test certificates) with chemical composition and mechanical properties, and evidence of in-house pressure testing equipment and procedures. Direct verification of manufacturing process control, particularly for critical dimensions like ball roundness, seat contact pattern, and stem-to-bore concentricity, is advisable before volume commitment.
