What certifications does the product hold?

The product holds FDA and CE certifications, and the manufacturer is ISO9001:2015 certified, ensuring high quality and safety.

How does the check valve work?

The valve opens when the pressure at the stem bottom exceeds the pressure above and the spring force, allowing one-way flow. It closes automatically to prevent backflow when pressures equalize.

AI-Powered supplier vetting

SummaryAVM Extraordinary Intelligent Control Equipment Co., Ltd. is a manufacturer and seller of valves, pumps, vacuum equipment, and related general and specialized equipment, serving pharmaceutical, food, beverage, and dairy applications. It reports CE product certification and ISO9001:2015 management certification. Production evidence includes stainless steel union output of 120,000 sets and equipment such as lathes, polishing machines, pressure testers, ultrasonic cleaning machines, laser marking machines, and CNC machinery. The supplier supports multiple customization modes and OEM services for popular brands. However, quality traceability is reported absent, corrective-action and complaint procedures lack written records, and there is no valid manufacturing-capacity contract with affiliated subcontractors. Overseas service infrastructure is limited, with no overseas warehouses, showrooms, agents, or branches. Financial information is only represented by years, without sufficient evidence to assess...

Supplier typeThe supplier is presented as an integrated design, production, sales, and service enterprise manufacturing valves, pumps, vacuum equipment, and other general or specialized equipment. Its stated applications include pharmaceutical, food, beverage, and dairy industries, indicating a direct manufacturer profile rather than only a trading role.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and CE product compliance certification. These are explicit certifications relevant to quality management and product conformity, although the provided information does not specify their scope or validity period.

After-Sales capabilityThe supplier has procedures for corrective and preventive actions and customer complaints, but no written records; it also lacks raw-material traceability identification. Overseas support is limited because it reports no overseas warehouse, showroom, agent, or branch, although it has inventory capability and stated lead times within 15 workdays in the peak season.

Production capacityProduction evidence includes annual stainless steel union productivity of 120,000 sets, equipment including CNC, lathes, polishing machines, pressure testers, ultrasonic cleaning and laser marking machines, inventory capability, six qualified service-capability suppliers, and peak-season fulfillment within 15 workdays. However, the supplier reports no valid manufacturing-capacity contract with affiliated subcontractors, which is a documented capacity-management weakness.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization, and also reports OEM service for popular brands. These statements directly support a broad customization and OEM offering.
