AI-Powered supplier vetting

SummaryLINKV VALVE presents itself as a valve-solution supplier with a stated 16-year service history, product R&D, manufacturing, logistics, and after-sales coverage. Its scope includes valves, pumps, industrial automation devices, seals, mechanical parts, fasteners, and related metal products, with import and export activities. The supplier reports ERP-based process management, documented corrective/preventive action and complaint-handling procedures, quality assurance in quality control, ODM and broad customization services. However, system certification is listed as NIL, overseas service infrastructure and offline trade-show participation are absent, no new products were reported in the past year, and no SDK or well-known-brand OEM capability is available. Financial figures are not assessed here due to privacy restrictions; the supplied zero entries do not establish financial credibility.

Supplier typeThe supplier is positioned as a valve-focused industrial equipment and components supplier. Its stated business scope covers valve and plug sales, pumps, industrial automation devices, seals, mechanical parts, fasteners, metal materials, and related products, alongside import and export activities.

CertificationsThe supplier states that its products can meet international standards such as API, ANSI, and DIN, but its supplier management system certification is explicitly listed as NIL. Product-standard references do not establish that the company itself holds management-system certifications.

It also states that it serves customers’ personalized needs and has documented service procedures, providing clear evidence of broad customization capability.

Product Q&A

Q:What is a trunnion mounted ball valve?

A trunnion mounted ball valve is designed with top and bottom trunnions to support the ball, ensuring lower torque, enhanced sealing, and stable operation in high-pressure applications.

Q:What is the difference between a trunnion ball valve and a floating ball valve?

Trunnion ball valves perform better under high pressure, provide lower operating torque, and reduce seat wear compared with floating ball valves.

Q:What industries use trunnion mounted ball valves?

Common industries include oil & gas, chemical processing, petrochemical, water treatment, steam systems, power generation, and industrial automation.

Q:Do your valves comply with 6D or 607?

Yes. Our trunnion ball valves meet 6D, 607 fire-safe requirements, and are available with DBB (Double Block & Bleed) configuration.

Q:What materials are available for LINKV trunnion ball valves?

Materials include Stainless Steel 304/316, CF8 / CF8M, WCB, carbon steel, and customized alloys for corrosive media.
