AI-Powered supplier vetting

SummaryThe supplier manufactures specialized equipment for oil refining and chemical production and also conducts hardware product manufacturing, research and development, sales, and related services. It reports ISO 9001 and ISO 14001 certification, two production lines, six to ten quality-control staff, and six to ten years of total R&D engineer experience. The supplier offers broad customization, OEM, and ODM services, with documented inspection, corrective-action, complaint-handling, and traceability procedures. Export experience is stated as 15 years, with 51%–70% of total sales from exports and self-operated import/export rights. However, it has no overseas agents or branches, warehouses, showrooms, or SDK availability; it also reports no new products in the past year and no valid manufacturing-capacity contract with related subcontractors. Customer cases are not specifically provided.

Supplier typeThe stated business scope includes manufacturing and sales of specialized equipment for oil refining and chemical production, hardware product manufacturing, hardware R&D, and ferrous metal casting. The company description also covers material purchasing, production, inspection, delivery, and after-sales service, indicating a manufacturer with integrated related operations.

CertificationsThe supplier reports holding ISO 9001 and ISO 14001 certifications. These are explicit certifications relevant to quality and environmental management systems.

After-Sales capabilityThe supplier states that its operations include after-sales service and has clear, followed procedures and records for handling customer complaints and corrective and preventive actions. However, it reports no overseas agents or branches and offers overseas services in zero countries, which limits directly evidenced overseas service coverage.

Production capacityThe supplier operates two production lines, maintains six to ten quality-control staff, has in-stock service capacity, and uses documented inspection, supplier assessment, corrective-action, complaint-handling, quality-assurance, and material-traceability procedures. Nevertheless, it reports no valid contract with associated subcontractors for manufacturing capacity, creating a documented weakness in subcontracting governance.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It also provides OEM services for well-known brands and ODM services, demonstrating broad stated customization and manufacturing-design support.

Product Q&A

Q:What is the primary function of this safety valve?

It is mounted on the liquid-phase backflow pipeline of LPG pump outlets to automatically open when pressure exceeds limits, ensuring safe equipment operation.

Q:What materials are available for the valve body?

The valve body is available in Carbon Steel (WCB), Stainless Steel (1cr18ni9ti), and Stainless Steel with Molybdenum (1cr18ni12mo2ti).

Q:How does the valve achieve closure?

It achieves closure by changing the relative position of two diaphragms through movement in two directions, driven by gravity and spring force.

Q:Is the valve suitable for bidirectional flow?

Yes, depending on the medium entry point, it can function as either a unidirectional or bidirectional flow control gate.

Q:What are the terms of payment?

We accept LC, T/T, Western Union, and Money Gram.
