SummaryQingdao Huaguan Valve Co., Ltd. is a China-based limited company established in 1994, with 96 employees and a product range including knife gate valves, check valves, fire hydrants, and gate valves. It reports ISO9001:2015 and CE/UL certifications, documented quality, corrective-action, and complaint-handling procedures, plus three quality inspectors and stated annual gate-valve productivity of 200,000 sets. The supplier offers full customization and has inventory capability, but lacks an SDK, overseas warehouses, overseas agents or branches, overseas showrooms, and offline trade-show participation. Manufacturing capacity is not supported by a valid contract with its factory or related subcontractors. Financial information identifies reporting years but does not provide sufficient performance data. No customer cases are documented in the provided slices.

Supplier typeThe supplier is identified as Qingdao Huaguan Valve Co., Ltd., a China-based limited company established in 1994, operating from Shandong with 96 employees. It is not part of a larger company group, and its stated product scope is focused on industrial valve products.

CertificationsThe supplier reports ISO9001:2015 and other management-system certifications, together with CE, UL, and other product-compliance certifications. These stated certifications provide explicit evidence of certification holdings, although the specific additional certificates are not identified.

R&D capabilityThe supplier reports full customization and identified production equipment, but explicitly states that no SDK is available. The evidence supports customization and manufacturing functions, not broader innovation or product-development strength.

Production capacityThe supplier reports annual gate-valve productivity of 200,000 sets, production equipment including automatic molding, CNC machining, vulcanizing, grinding, and pressure-testing equipment, three quality inspectors, and one-month lead times in peak and off-peak seasons. However, it explicitly lacks a valid contract covering the factory and related subcontractors, which is a documented production-capacity risk.

Customization capabilityThe supplier explicitly reports full customization design capability. This is supported by documented finished-product inspection instructions, quality assurance, and corrective and preventive action procedures.
