AI-Powered supplier vetting

SummaryThe supplier is identified as a Ningbo-based trading company with professional technical capabilities, including 3D software design, ODM, OEM, and multiple customization options. It reports ISO9001 certification and CE and UL approvals for specified valve products. Production information indicates substantial output across valves, air vents, ferrules, and pipe fittings, supported by 6–10 quality-control staff and broad export coverage, with 90% of sales from exports. Service procedures for corrective actions and complaint handling are documented and followed. However, the supplier has no overseas showroom, agents, branches, offline trade-show participation, overseas warehouse, or in-stock service capability. No new products were reported in the past year, no SDK is available, and financial evidence is limited to stated years without performance details.

Supplier typeThe company is explicitly classified as a trading company located in Haishu District, Ningbo, while also identifying itself as a professional technical supplier with R&D capability. This indicates a trading-oriented supplier with technical and design-service functions rather than evidence of a purely manufacturing company.

CertificationsThe company description states that it passed ISO9001 certification and holds CE approval for ball valves and UL approval for bronze ball valves. These certifications and approvals are explicitly reported, although their scope is limited to the products named.

After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions and customer complaint handling. However, it reports no overseas agents or branches, no overseas showroom, no overseas warehouse, and no in-stock service capability, so documented complaint processes coexist with limited overseas service infrastructure.

Production capacityReported annual output includes 1,230,000 brass valves, 250,000 bronze valves, 235,000 air vents, 250,000 gunmetal ferrules, and 1,870,000 pipe fittings, supported by 6–10 quality-control staff and access to Ningbo and Shanghai ports. Nevertheless, manufacturing-capacity reconciliation, outsourcing procedures, and contracts are all listed as unknown, preventing a complete assessment of capacity controls.

Customization capabilityThe supplier explicitly offers flexible customization, minor customization, customization from samples and designs, and full customization. It also provides ODM and OEM services, directly supporting broad product-design and customization capability.

Product Q&A

Q:Can this 3PC brass ball valve be used for oxygen pipeline directly?

Standard stock product is for general water/gas only. We can do professional ultrasonic degreasing, solvent oil-free cleaning and oxygen service treatment for bulk orders, with cleaning record provided, safe for pure oxygen working condition.

Q:What is the advantage of 3-piece structure compared with 2-piece ball valve for oxygen service?

3-piece valve can be fully split and disassembled, we can thoroughly clean every internal corner to remove all grease residue. Two-piece valve cannot be fully opened for deep cleaning, which has hidden safety hazards for oxygen gas.

Q:What pressure can this three piece ball valve bear?

Rated 600WOG working pressure, fully meet the pressure requirement of conventional industrial oxygen and compressed air pipelines.

Q:What's your MOQ for oxygen service cleaned valves?

Standard MOQ 500pcs for regular specification; small trial order is acceptable with extra cleaning processing cost.

Q:Will the valve leak after long-term frequent operation?

Equipped with wear-resistant PTFE sealing seats, reach bubble-tight zero leakage standard, stable sealing performance after thousands of open-close cycles.
