Key features

Extreme Corrosion Resistance: Fluoroplastic lining resists strong acids, bases, and oxidizers, replacing expensive Hastelloy or titanium valves.

Detachable Adjustable Design: Built-in adjustment bolts allow seal restoration without replacing the entire valve, reducing maintenance costs.

Bi-Directional Zero Leakage: Four-level elastic composite sealing ensures zero leakage under forward and reverse pressure for toxic media.

Sturdy Flange Structure: Bolt locking provides superior shock and pressure resistance compared to wafer types for underground pipelines.

100% Pressure Tested: Every valve undergoes bidirectional pressure zero-leak testing with full traceability via ERP system.

Customized Standards Available: Manufacturing capability for GOST and JIS standards according to specific pressure, temperature, and size needs.

Wide Application Range: Suitable for pharmaceutical, new energy, chemical, power, petroleum, metallurgy, and steel industries.

AI-Powered supplier vetting

SummaryThe supplier demonstrates broad customization, ODM availability, 100% finished-product inspection, two production lines, and access to CNC, molding, machining, oven, press, and spraying equipment. It holds ISO9001:2015 and CE certifications and reports lead times within 15 working days in both peak and off-peak periods. However, service-management controls are incompletely documented, with procedures lacking written records in several areas. The supplier has no valid manufacturing-capacity contract with related subcontractors, no overseas warehouse or showroom, no recent new-product development, no SDK, and no OEM service for popular brands. Financial information is inconsistent across the supplied records, so financial credibility cannot be reliably assessed. Export-trade experience and total experienced staff are each reported as one, while batch quantity reconciliation and outsourcing SOPs are absent.

Supplier typeThe supplier is a manufacturing-oriented provider with two production lines, extensive machining and processing equipment, ODM availability, and export terms including FOB, CIF, and CFR. It also reports inventory capability, but lacks a valid manufacturing-capacity contract with related subcontractors and has no overseas warehouse or showroom.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and CE product compliance certification. These are explicit certifications supporting quality-management and product-compliance capability.

After-Sales capabilityThe supplier has records for service-capability assessment, an approved-supplier list, and procedures for corrective actions and complaint handling. However, the corrective-action and complaint-handling procedures have no written records, and the service-assessment procedure is not formally written, indicating incomplete service-control documentation.

R&D capabilityThe supplier offers ODM services and broad design customization, but reports no available SDK and no new products during the past year. The evidence supports design-service capability more strongly than ongoing product innovation.

Production capacityProduction capability is supported by two production lines, a broad equipment set covering CNC machining, turning, molding, boring, milling, pressing, oven processing, and spraying, inventory capability, and reported lead times within 15 working days in both peak and off-peak periods. Offsetting weaknesses include no valid manufacturing-capacity contract with related subcontractors and no continuous batch quantity reconciliation.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization, and also provides ODM services. This is direct evidence of broad customization coverage.

Client casesThe supplier states that it does not provide OEM services for popular brands. No specific customer names, completed projects, or verifiable customer cases are provided in the supplied slices.
