How does the backflushing mechanism work?

When external pressure enters the diaphragm control cavity, the valve core moves up to close the inlet and open the sewage outlet for backwash. When pressure is discharged, spring elasticity returns the valve to the filter mode.

AI-Powered supplier vetting

SummaryThe supplier is identified as a factory with automatic extrusion, injection molding, mixing, and laser engraving equipment. It supports extensive customization, OEM and ODM services, and has documented inspection, service, complaint-handling, and corrective-action procedures. ISO9001:2015, ISO45001:2018, and ISO14001 certifications are reported. Financial records are indicated for 2022–2024, but the slices do not provide financial results or solvency evidence. Innovation-related evidence is mixed: the supplier reports technical cooperation and past innovation recognition, but had no new product in the past year, no SDK, and only two R&D engineers. Overseas infrastructure is limited, with no overseas warehouse, showroom, agent, branch, or offline trade-show participation. Customer evidence includes cooperation with domestic and overseas irrigation companies, but no Fortune 500 collaboration.

Supplier typeThe supplier explicitly identifies itself as a factory and lists production equipment including automatic extruders, injection molding machines, mixing machines, and laser engraving machines. This supports classification as a manufacturing supplier rather than only a trading or service company.

CertificationsThe supplier reports holding ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications. These explicitly reported certifications support a positive assessment for formal quality, occupational safety, and environmental management coverage.

After-Sales capabilityThe supplier has written procedures and records for service capability assessment, corrective and preventive actions, and customer complaints, and describes overseas services as debugging, repair, and maintenance. However, it has no overseas warehouse, showroom, agent, or branch, so the documented process strength is not matched by an overseas physical service network.

R&D capabilityThe supplier reports technical cooperation with the Fujian Provincial Agricultural Science and Technology Research Center, a professional product design and R&D team, past science-and-technology recognition, and ODM capability. Countervailing evidence includes no new product in the past year, no available SDK, and only two R&D engineers, so innovation capability is supported but limited and mixed.

Production capacityThe factory lists multiple automated production machines and reports average peak- and off-season lead times within 15 workdays. These details provide explicit evidence of established manufacturing equipment and stated delivery capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides OEM and ODM services, indicating broad product adaptation and development support.

Client casesThe supplier states that it has established cooperative relationships with several advanced professional irrigation companies domestically and internationally and provides OEM services for well-known brands. However, it reports no Fortune 500 cooperation, and no named customer cases or verifiable project details are supplied.
