Key features

Spiral Wound Gasket for Flange Sealing: Alternating metal windings and a graphite or PTFE filler form a resilient, self-reinforcing seal that maintains contact pressure through temperature and pressur

Leak Prevention in Cycling Service: Soft gaskets relax and blow out under repeated heating and cooling; a spiral wound gasket keeps sealing force roughly constant, reducing unplanned release.

ASME B16.20, SS304/SS316: Available with metal windings in 304 or 316 stainless and graphite or PTFE filler, in R and RX style for standard and high-pressure flanges.

Heat Exchangers, Pipelines and Vessels: Widely used on flange joints in petrochemical, power, pulp and paper and food plants, especially where temperature swings are common.

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.

After-Sales capabilityThe supplier reports a full-chain service system including logistics and after-sales support, documented corrective and preventive action procedures, and documented customer-complaint handling. However, it has no overseas showroom, agent or branch, and reports service coverage in zero countries, limiting demonstrated overseas service reach.

Production capacityThe supplier states that it has operated for 16 years and maintains a full-chain system covering product R&D and manufacturing, supported by Wenzhou’s valve-industry supply chain and ERP management across production, procurement, quality control, and logistics. These statements explicitly support manufacturing and operational capability.

Customization capabilityThe supplier explicitly provides customization from samples, designs, full customization, minor customization, and flexible customization, as well as ODM services. It also states that it serves customers’ personalized needs and has documented service procedures, providing clear evidence of broad customization capability.
