AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company associated with manufacturing-sector companies and operates 12 production lines. It manufactures ordinary valves and plugs and provides valve-related sales and R&D activities. Customization and ODM services are available, supported by recent new-product information, while finished-product inspection and service-management procedures are documented and followed. However, the supplier holds no stated management-system certifications, has limited export experience of two years with one export-trade staff member, and reports no overseas warehouses, showrooms, agents, branches, or offline trade-show participation. Production capability is substantial by line count, but continuous quantity reconciliation is not performed for each batch or production volume. Financial information is insufficient for a credibility judgment, and no customer cases are provided.

CertificationsThe supplier’s certification of management systems is explicitly listed as NIL. This indicates no stated management-system certification in the provided information.

After-Sales capabilityThe supplier has written procedures and followed records for service evaluation, corrective and preventive actions, and customer complaints. However, it reports no overseas warehouse, showroom, agent or branch, offline trade-show participation, or overseas service country coverage, limiting evidence of international service reach.

R&D capabilityThe supplier reports two years of total R&D engineer experience, new product information within the past year, ODM availability, and broad design-service options. It does not provide an SDK and does not serve as an OEM supplier for popular brands, so the evidence supports basic product-development capability but not broader technical integration or brand-OEM strength.

Production capacityThe supplier reports 12 production lines and equipment including CNC lathes, lathes, drilling machines, and winding machines, with valve and plug manufacturing in its stated scope. Finished-product inspection instructions are uniformly followed, but continuous quantity reconciliation is not performed for every batch or production volume.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full and minor customization, flexible customization, and ODM services. These consistent statements provide direct evidence of broad customization capability.

Product Q&A

Q:What is the recommended continuous energization time for the coil?

For standard models, continuous energization should be within 60 minutes. For long-term operation, use an energy-saving module for 24+ hours without overheating.

Q:How does the Normally Closed (NC) and Normally Open (NO) function?

NC opens when energized and closes when power is off. NO closes when energized and opens when power is off, requiring at least 0.5 KG pressure to open.

Q:What precautions should be taken when using with controllers?

Set both upper and lower limits on temperature controllers or sensors to allow rest intervals. Setting only one limit causes frequent operation and coil burnout.

Q:How should the valve be installed regarding flow direction?

Install according to the arrow on the valve body or base indicating flow direction. Do not install in reverse.

Q:What are the requirements for dirty media or outlet pressure?

If the medium is dirty, install a filter. If pressure exists at the outlet, install a check valve. This product is not suitable for media with large particles.
