AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company with a combined company type and a business scope covering valves, industrial automation devices, hardware, metal products, machinery, pumps, vacuum equipment, and power-related products. It reports OEM service for popular brands, ODM and multiple customization options, and describes access to precision CNC machining and comprehensive testing equipment; however, other evidence indicates no valid manufacturing-capacity contract with affiliated subcontractors. The supplier has ISO9001:2015, ISO45001:2018, and ISO14001 certifications. Service procedures exist for capability assessment, corrective and preventive actions, and customer complaints, but no records were provided. It has no in-stock capacity, overseas warehouse, or overseas showroom, while overseas service offerings include debugging. Financial records are identified for 2023–2025, but the provided slices do not establish their adequacy. Innovation evidence is limited because no new products were...

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications, providing explicit evidence of quality, occupational health and safety, and environmental management certification. The slices do not provide certificate validity dates or issuing-body verification details.

R&D capabilityThe supplier reports ODM capability and multiple design-service options, including customization from samples, designs, full customization, minor customization, and flexible customization. However, it reports no new products in the past year and no available SDK, which are explicit limitations for recent product innovation and software-development support.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, together with ODM services. These statements directly support a broad customization offering, although the slices do not provide project examples, technical specifications, or delivery-performance evidence.

Client casesThe supplier states that it provides OEM services for popular brands, which is evidence of experience serving recognized-brand customers. No customer names, product examples, order records, or independently verifiable case details are provided, so the depth and verifiability of these cases remain limited.

Product Q&A

Q:What is this pneumatic valve used for?

It is an automatic on-off valve driven by compressed air, suitable for automatic control in pipelines, water tanks, boilers, water treatment, chemical industry and other applications.

Q:Which type should I choose for water, air, oil or chemical media?

Water, air, general wastewater: Cast iron / Ductile iron + NBR seal. Weak acid & alkali, food & pharmaceutical: Stainless steel 304/316 + FKM. Strong acid & alkali, high temperature: Cast steel + PTFE / FKM seal. Just tell us your medium, and we can help you select the right one.

Q:What is the difference between double-acting and single-acting? What happens when power or air is cut off?

Single-acting (spring return): Automatically opens or closes when power or air is cut off (as you prefer). Double-acting: Remains in its current position when power or air is cut off. Single-acting normally closed is the safest choice for general working conditions.

Q:How long is the warranty? Can it be repaired if broken?

The whole unit is under 18-month warranty with lifelong after-sales service.

Q:Which actuator size matches the valve? I'm afraid of choosing the wrong one.

We will automatically match the actuator model according to your valve size, pressure and medium.
