AI-Powered supplier vetting

SummaryThe supplier demonstrates established customization and R&D capabilities, including sample-, design-, minor-, full-, and flexible-customization services, ODM availability, recent new-product development, and eight utility model patents. Production-related evidence includes CNC and assembly equipment, an automated solenoid-valve testing system, documented finished-product inspection instructions, and two quality inspectors. The supplier holds ISO9001:2015 and CCC certifications and reports OEM service for well-known brands. Service management procedures for supplier capability, corrective and preventive actions, and customer complaints are documented and followed. However, overseas service infrastructure is limited: there are no overseas warehouses, showrooms, agents, or branches, and the stated number of countries served overseas is zero. Financial records are referenced for multiple years, but the provided slices do not establish financial strength or credibility. Customer-specific cases are not identified.

Supplier typeThe supplier is presented as an R&D-oriented manufacturer offering ODM services, OEM services for well-known brands, and pneumatic technology expertise. Its stated capabilities include both standard-product modification and fully customized technical solutions.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and CCC product compliance certification. These explicitly support quality-management and product-compliance credentials.

After-Sales capabilityThe supplier has documented and followed procedures for handling customer complaints and corrective/preventive actions. However, it has no overseas warehouse, showroom, agent, or branch, and reports service coverage in zero countries, limiting evidenced overseas after-sales infrastructure.

R&D capabilityThe supplier reports new products within the past year, an R&D team focused on pneumatic technology, an available SDK, one national science and technology progress award, and eight utility model patents. These are explicit indicators of active innovation and technical development.

Production capacityThe supplier lists assembly, CNC lathe, CNC machining center, drilling, laser marking, and automated solenoid-valve testing equipment. It also reports uniformly followed finished-product inspection instructions and one-month peak and off-peak lead times, supporting an established production process.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full, minor, and flexible customization, supported by a professional R&D team and tailored technical design assistance. ODM service is also available.

Product Q&A

Q:What is the difference between double pilot and single pilot valves?

Double pilot valves (like 4A320-10) have no return spring, so they maintain their position even without pilot pressure (memory function), while single pilot valves reset to their original position when pilot pressure is removed.

Q:Is this valve compatible with AirTac 4A320-10?

Yes, it is fully interchangeable with the AirTac 4A320-10 model in dimensions, function and thread size.

Q:What is the minimum pilot pressure required?

The minimum pilot pressure is 0.15 MPa 1.5 kgf/cm, which is consistent with the working pressure range.
