SummaryWinner Ball Valves Co., Ltd. is a China-based limited company established in 2010, with 24 employees and operations in Changsha, Hunan. It presents itself as a manufacturer of small electric ball valves and related control products for HVAC, heating, solar, industrial, and medical applications, while another record classifies the company as a trading company. The supplier states that it follows ISO 9001 production practices, performs 100% functional testing, and holds ISO 9001:2015, CE, and RoHS certifications. It claims OEM and ODM experience, international sales, recognized customers, and long-term cooperation relationships, but the provided data does not identify most customers or substantiate production scale. After-sales service and technical support are stated commitments, while quality-control staffing is not disclosed. Innovation is supported by stated development activities and patent certificates, although the extent of R&D capability is unclear.
CertificationsThe supplier explicitly reports an ISO 9001:2015 certificate and production according to ISO 9001 standards, including 100% functional testing and production-line visualization controls. It also states that its products have CE and RoHS certifications, but the provided slices do not include certificate numbers, validity dates, or scopes.
R&D capabilityThe supplier states that it emphasizes innovation and development, develops multiple electric-valve products, and holds multiple patent certificates. Its reported total R&D engineer experience is 2, but the slices do not clarify whether this refers to two engineers, two years, or another measure, so the depth of innovation capability cannot be fully verified.
Customization capabilityThe supplier explicitly states that it provides OEM and ODM services, which supports capability for product customization or private-label development. The available information does not specify customization scope, engineering workflow, minimum order requirements, or examples of customized products.
Client casesWINNER claims recognition from well-known companies, long-term cooperation relationships, and worldwide sales, and one trade record associates it with HIGHZ VALE INDUSTRIA ELETRONICA LTDA. The evidence is limited because most claimed customers are unnamed and only one transaction is shown in the provided trade record.
