Key features

Triple Eccentric Zero Leakage: Triple offset disc and seat geometry eliminates friction for bubble-tight metal-to-metal sealing.

Hard Sealed Construction: Made from hardened stainless steel or specialized alloys for superior resistance to abrasion and corrosion.

Low Torque Smooth Operation: Disc lifts away from seat immediately upon opening, reducing operating torque and extending lifespan.

Long Service Life: No sliding contact between sealing surfaces reduces wear, requiring minimal maintenance and lowering costs.

Versatile Applications: Ideal for steam, gas, oil, chemical systems, and water supply/drainage in municipal and industrial sectors.

Multiple Drive Options: Supports effortless manual, gear, or actuator-driven control for flexible installation and operation.

AI-Powered supplier vetting

SummaryThe supplier is a combined valve manufacturing company with reported design, development, production, sales, installation, maintenance, and service capabilities. It offers broad customization, ODM services, OEM services for popular brands, and has reported new-product development, 12 R&D patents, and auditable design documentation. Quality-related evidence includes ISO9001, ISO14001, OHSAS18001, CE, TS, and CCC certifications, plus documented finished-product inspection instructions that are uniformly followed. However, several service-control procedures lack written records, the supplier has no valid manufacturing-capacity contract with an affiliated subcontractor, and it reports no overseas branches, agents, warehouse, showroom, offline trade-show participation, or overseas service countries. Financial credibility cannot be determined from the provided slices because the financial entries only identify years and do not provide assessable financial results.

Supplier typeThe supplier is identified as a combined company rather than an offshore entity. Its stated business scope covers valve design, development, production, sales, installation, maintenance, and service, indicating an integrated manufacturing-and-service supplier profile.

CertificationsThe company reports ISO14001 environmental, ISO9001 quality, OHSAS18001 occupational health and safety, CE, TS, and CCC certifications. These are explicit certifications relevant to environmental management, quality management, occupational safety, and product or market compliance.

R&D capabilityThe supplier reports new products during the past year, ODM capability, an available SDK, 12 R&D patents, and auditable documentation covering design inputs, outputs, reviews, verification, and validation. R&D personnel are also described as responsible for product improvement and production support, providing explicit evidence of structured innovation capability.

Production capacityProduction evidence includes CNC machines, drilling machines, and lathes; a stated valve manufacturing base; uniformly followed finished-product inspection instructions; inventory capability; and quality assurance in quality-control processes. Nevertheless, the supplier reports no valid manufacturing-capacity contract with an affiliated subcontractor, so the full reliability and scalability of production capacity remain partly unverified.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM services, demonstrating broad stated capability across both customer-provided and supplier-developed designs.
