AI-Powered supplier vetting

SummaryDonjoy demonstrates broad manufacturing, customization, OEM/ODM, and R&D capabilities. It operates eight production lines, reports annual sanitary butterfly valve output of 200,000 pieces, and has eight quality inspectors. The supplier indicates ISO, environmental, occupational safety, CE, PED, MD, 3A, TS, ASME BPE, EHEDG, and FDA-related compliance or certification experience. It reports overseas agents or branches, export markets across multiple regions, and proximity to Ningbo and Shanghai ports. However, it has no stated in-stock capacity, overseas warehouse, overseas showroom, valid manufacturing-capacity contract with associated subcontractors, or offline trade-show participation. Financial evidence is limited to referenced years and does not provide sufficient information to assess credibility. Customer-case evidence is also insufficient because OEM service is stated without named customers or documented cases.

Supplier typeThe supplier presents itself as a manufacturer with machining, polishing, welding, blasting, ultrasonic cleaning, assembly, and CNC capabilities, while also offering OEM, ODM, and R&D services. Its product and process information supports classification as a manufacturing supplier rather than only a trading intermediary.

CertificationsThe company description cites production according to ASME BPE, EHEDG, FDA, and 3A standards, plus PED, MD, 3A, TS, and ISO9001:2008 credentials. Additional records identify ISO9001:2015, ISO14001, ISO45001:2018, and CE certification capability, providing explicit evidence of multiple quality, environmental, safety, and product-compliance credentials.

R&D capabilityThe supplier reports new products during the past year, ODM service, an R&D center, high-tech and innovative-enterprise recognition, and patent-model-enterprise status. It also uses an ERP system for digitized production, procurement, quality, and logistics management, although no SDK is available.

Production capacityProduction evidence includes eight production lines, eight quality inspectors, annual sanitary butterfly valve output of 200,000 pieces, one-month stated lead times, 30 qualified service-capability suppliers, and access to Ningbo and Shanghai ports. Nevertheless, the supplier reports no valid manufacturing-capacity contract with associated subcontractors, so capacity strength is supported but not fully risk-free.

Customization capabilityBoth R&D and design-capability records explicitly list customization from samples, customization from designs, full customization, minor customization, and flexible customization. The supplier also reports ODM capability and recent new-product development, directly supporting broad customization capability.

Product Q&A

Q:What materials are available for the valve body and seats?

The valve body is made of AISI 304 or 316L stainless steel. Seat materials include Silicone (default), EPDM, or FPM, allowing selection based on specific media requirements.

Q:What certifications does the product hold?

The product holds 3A, CE, and FDA certifications. The production management system complies with ISO9001-2008 standards.

Q:What is the minimum order quantity (MOQ)?

The minimum order quantity is 1 Pc, making it suitable for small orders or sampling.

Q:What are the lead times for production?

Lead times depend on the season: peak season requires one month, while off-season production takes within 15 workdays.

Q:How does the check valve operate?

The valve opens when fluid pressure exceeds spring pressure and closes when pressures equalize or counter-pressure increases, preventing backflow and pipe hammering.
