AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company with a combined company type and a business scope covering valves, industrial automation devices, hardware, metal products, machinery, pumps, vacuum equipment, and power-related products. It reports OEM service for popular brands, ODM and multiple customization options, and describes access to precision CNC machining and comprehensive testing equipment; however, other evidence indicates no valid manufacturing-capacity contract with affiliated subcontractors. The supplier has ISO9001:2015, ISO45001:2018, and ISO14001 certifications. Service procedures exist for capability assessment, corrective and preventive actions, and customer complaints, but no records were provided. It has no in-stock capacity, overseas warehouse, or overseas showroom, while overseas service offerings include debugging. Financial records are identified for 2023–2025, but the provided slices do not establish their adequacy. Innovation evidence is limited because no new products were...

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications, providing explicit evidence of quality, occupational health and safety, and environmental management certification. The slices do not provide certificate validity dates or issuing-body verification details.

R&D capabilityThe supplier reports ODM capability and multiple design-service options, including customization from samples, designs, full customization, minor customization, and flexible customization. However, it reports no new products in the past year and no available SDK, which are explicit limitations for recent product innovation and software-development support.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, together with ODM services. These statements directly support a broad customization offering, although the slices do not provide project examples, technical specifications, or delivery-performance evidence.

Client casesThe supplier states that it provides OEM services for popular brands, which is evidence of experience serving recognized-brand customers. No customer names, product examples, order records, or independently verifiable case details are provided, so the depth and verifiability of these cases remain limited.

Product Q&A

Q:How to choose the size?

Size is determined by nominal diameter (DN). Common sizes include DN25, DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300, DN350, DN400 and larger.

Q:What media is it suitable for?

Butterfly valves can be used for water, air, oil, weak acid, and alkali. Strong corrosive media requires lined or stainless steel types, while high-temperature media needs metal-sealed valves.

Q:How to judge the quality of a butterfly valve?

Look for heavier weight indicating better material, smooth casting without pores, smooth operation without jamming, good sealing performance, and a complete nameplate with identification.

Q:Are there national and industrial standards?

Yes, the main Chinese standard is GB/T 12238. Regular products include a nameplate, certificate, and marked pressure, diameter, and material.

Q:Is installation difficult?

No, installation is simple. Wafer type is clamped between flanges, and flange type is bolted directly to pipes. Just follow the flow direction arrow.
