AI-Powered supplier vetting

SummaryWenzhou Valvespro Flow Control Technology Co., Ltd. is identified as a Chinese manufacturer/factory specializing in electric and pneumatic actuators and automatic control valves. The supplier reports ISO 9000, ISO 14001, and ISO 9001 management certifications, CE certification for all products, five production lines, 6–10 quality-control staff, and annual capacities of up to 100,000 sets for several actuator and valve categories. It has self-operated import and export rights and began exporting in 2017. The company describes CAD, CIMS, machining-center, and CNC capabilities, as well as consulting, design, type selection, installation, and control-program support. It also states that it has supplied hundreds of thousands of product sets. Evidence is insufficient to assess financial credibility, while after-sales capability and customization capability are only partially supported.

Supplier typeThe supplier is explicitly classified as a manufacturer/factory and limited company, while its associated-company industry is wholesale and retail. Its stated business focuses on R&D and manufacturing of electric and pneumatic actuators and automatic control valves, indicating a manufacturing-oriented supplier rather than only a trading intermediary.

CertificationsThe supplier states that it implements the ISO9000 quality certification system, holds ISO 9000, ISO 14001, and ISO 9001 management-system certifications, and that all products have CE certification. These are explicit certification claims supporting quality-management and product-compliance capability.

R&D capabilityThe supplier reports R&D specialization, CAD development design, CIMS computer-network management, machining centers, CNC tools, and 6–10 years of total R&D-engineer experience. These stated technical resources provide explicit evidence of engineering and development capability.

Production capacityThe supplier reports five production lines and annual capacities of 100,000 sets each for electric actuators, pneumatic actuators, and angle seat valves, plus 50,000 pieces each for electric control actuators and butterfly valves. Its description also cites advanced production processes, complete testing equipment, machining centers, and CNC tools, supporting substantial production capability.

Client casesThe supplier states that it has provided hundreds of thousands of sets of electric actuators, electric ball valves, electric butterfly valves, pneumatic ball valves, pneumatic butterfly valves, and pneumatic/electric control valves. This is evidence of substantial delivery experience, although named customers, project references, industries served, and independently verifiable case details are not provided.
