What materials are used for the valve components?

The valve body uses SEMI standard 316L rod (316L VAR/VIM-VAR optional), the diaphragm uses Hastelloy or nickel-cobalt alloy, and the seat uses PCTFE or PFA.

How do you ensure product quality before delivery?

100% of products undergo pressure and helium leak detection tests, as well as functional tests, before leaving the factory.

What is the working pressure range?

The maximum working pressure is 3500psig (241bar) for manual versions and 3000psig (206bar) for pneumatic versions.

AI-Powered supplier vetting

SummaryThe supplier is a limited company with 47 employees and offers valves, fittings, pressure regulators, and related industrial products. It reports manufacturing-related capabilities supported by CNC and vision-measuring equipment, valid contracts with associated subcontractors, inventory capability, and documented inspection and service procedures. The supplier provides broad customization and ODM services, has introduced new products within the past year, and provides OEM services for recognized brands. However, no certification information, customer case details, or explicit after-sales service scope is provided. Financial information is identified only by years, without substantive financial metrics, so financial credibility cannot be assessed. The supplier has no overseas warehouse or showroom and no available SDK.

After-Sales capabilityThe supplier has written procedures and records for service assessment, corrective and preventive actions, and customer complaint handling, indicating a documented service-management process. However, no specific after-sales services, response standards, or support coverage are stated.

R&D capabilityThe supplier reports new products within the past year, provides ODM services, and conducts research and development in emerging energy, Internet of Things, valve, and automatic-control technologies. It has no available SDK, which limits evidence of software-development integration capability but does not negate the stated product R&D capability.

Production capacityProduction capability is supported by CNC and vision-measuring equipment, uniformly followed finished-product inspection instructions, valid manufacturing contracts with associated subcontractors, and inventory capability. The supplier also reports 47 employees, but overall production capacity and output volume are not stated.

Customization capabilityThe supplier explicitly supports customization from samples and designs, minor and full customization, and flexible customization. It also reports ODM services and OEM services for recognized brands, providing strong direct evidence of customization capability.
