AI-Powered supplier vetting

SummaryTianjin Zhonghui Valve Industry Co., Ltd. is a China-based valve manufacturer established in 2017, with a 5,000 m² manufacturing plant, 16 employees, five production lines, and stated annual butterfly-valve output of 101,000 sets. Its product range includes butterfly, marine, check, gate, ball, and globe valves, with butterfly valves manufactured to DIN, ANSI, API, JIS, BS, and GB standards. The supplier reports ISO 9001:2015 certification and CE certification obtained in 2019. Export markets include Southeast Asia, the Middle East, and Europe, and trade records show transactions with a Philippine buyer in 2025 involving marine and butterfly valves. Evidence supports manufacturing and certification strengths, while after-sales capability, innovation depth, financial credibility, and broader customer-case history remain insufficiently documented.

Supplier typeThe supplier is identified as Tianjin Zhonghui Valve Industry Co., Ltd., a valve manufacturing company specializing in the design and manufacture of butterfly and other industrial valves. Although one record classifies the company nature as a trading company, the supplier type is explicitly stated as Manufacturer and its operations, products, and address support manufacturing activity.

CertificationsThe supplier states that it passed ISO 9001:2015 certification in 2019 and obtained CE certification in the same year, with ISO 9001:2015 specifically listed as a management-system certificate. These certifications provide explicit evidence of quality-management and European conformity credentials.

Production capacityProduction capability is supported by a 5,000 m² manufacturing plant, five production lines, stated output of 101,000 butterfly-valve sets, and a product range covering multiple industrial and marine valve types. The supplier also reports 6–10 quality-control staff and exports to Southeast Asia, the Middle East, and Europe.

Customization capabilityThe supplier states that it can produce wafer, lug, and double-flange butterfly valves according to DIN, ANSI, API, JIS, BS, and GB standards. This explicitly demonstrates configuration and standards-based customization for butterfly valves, though customization beyond these stated product formats and standards is not documented.

Client casesTrade records show three 2025 transactions involving marine storm valves and a JIS flange butterfly valve supplied to TAITECH MARINE SALES AND SERVICES in the Philippines. These records provide one identifiable buyer case and evidence of delivered product categories, but they do not establish a broad or extensive customer portfolio.
