AI-Powered supplier vetting

SummaryThe supplier is identified as a combined company with manufacturing, export, service, quality-control, and R&D information provided. It reports extensive customization, ODM and OEM capability, new-product activity within the past year, and 27 years of exporting experience. Production-related evidence includes fully automatic extrusion and injection-molding equipment, 66 quality inspectors, documented finished-product inspection procedures, and a one-month average lead time in both peak and off-season periods. However, the supplier reports no quality assurance capability, no in-stock service, no overseas warehouse, no overseas agents or branches, no overseas showroom, and no offline trade-show participation. Its financial credibility cannot be assessed from the provided records because the financial entries only identify reporting years and contain no usable financial results. Customer evidence is limited to one named buyer and one recorded trade transaction.

Supplier typeThe supplier is classified as a combined company and provides information covering manufacturing, export trade, service, quality control, R&D, and sustainable development capabilities. This supports classification as a manufacturing-oriented combined supplier rather than an offshore company.

CertificationsThe supplier explicitly reports no quality assurance capability. No certification names or valid certification records are provided, so certification holding cannot be positively established; the stated absence of quality assurance is a specific deficiency.

R&D capabilityThe supplier reports that it had new products during the past year and provides ODM services, indicating active product-development capability. It also reports no available SDK, which limits evidence of software or developer-integration capability but does not negate its manufacturing R&D capability.

Production capacityProduction evidence includes fully automatic extrusion and injection-molding equipment, raw-material processing machinery, 66 quality inspectors, documented finished-product inspection procedures, and a one-month average lead time in both peak and off-season periods. Nevertheless, the supplier reports no valid manufacturing-capacity contract with affiliated subcontractors, so subcontracting governance remains a weakness.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. These capabilities are stated consistently across the R&D and design-service records, providing direct evidence of broad customization coverage.

Product Q&A

Q:What does OS&Y / rising stem mean for this gate valve?

OS&Y (Outside Screw & Yoke) rising stem means the valve stem extends out when opening the valve. You can directly judge open/closed state by stem height, much safer for fire pipeline inspection compared with non-rising stem type.

Q:What working temperature and medium is this valve suitable for?

Designed for water medium, applicable temperature range is 0 to 80 degree Celsius, fit for clean tap water, domestic sewage and conventional industrial water conveying.

Q:What nominal sizes do you have available?

Complete size range: DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300, DN350, DN400, DN450, DN500, DN600; customized production can be negotiated for special requirements.

Q:Is this valve bidirectional sealing? Can fluid flow both directions?

Yes, the fully rubber coated wedge realizes bidirectional tight sealing, medium can flow in two directions without leakage risk.

Q:What material is the valve body made of?

Main valve body and bonnet adopt high-strength ductile iron; gate wedge is ductile iron base coated with NBR rubber; stem is 2Cr13 stainless steel.
