In 2025, the Bosnia and Herzegovina urban water supply pipeline upgrade project, aiming to address issues such as leakage and insufficient durability of aging pipe networks, publicly procured gate valves compatible with European standards. Yuming Valve Group, leveraging its mature technology, reliable quality, and experience in adapting to the European market, successfully partnered with a local trading company. The company supplied a batch of German standard ductile iron hard-seal gate valves for the project. After being put into use, the products operated stably, effectively solving the pain points of replacing local water supply pipelines and contributing to the upgrading of the urban water supply system in Bosnia and Herzegovina.
1. Product Standard Compatibility: The project required the procurement of ductile iron hard-seal gate valves conforming to the DIN 3352 German standard, compatible with the European system water supply pipelines in Bosnia and Herzegovina, ensuring precise compatibility of flange connections and structural lengths with the existing pipeline network.
2. Operating Performance Requirements: For urban tap water transportation (normal temperature, low pressure conditions), the valve body must be corrosion-resistant and freeze-crack resistant, with a hard-seal structure ensuring zero leakage and wear resistance, suitable for outdoor buried environments, and requiring minimal maintenance for long-term operation.
1. Customized Solution: Leveraging the group's DIN standard valve R&D and manufacturing system, customized ductile iron (GGG40) hard-seal gate valves are produced, strictly adhering to DIN 3352 standards in design and manufacturing. The valve body is precision cast, high-strength, freeze-resistant, and corrosion-resistant; the sealing surface utilizes a metal hard-seal process, offering wear resistance, erosion resistance, and a tight seal, suitable for tap water media and the climate of Bosnia and Herzegovina.
2. Quality Control: From raw material intake, precision casting, machining to sealing grinding and pressure testing, a full-process quality inspection is implemented. Each valve passes DIN standard sealing and strength tests to ensure compliance with European water supply equipment standards.
1. Product Delivery: Production, quality inspection, and packaging of all DIN standard ductile iron hard-seal gate valves are completed according to the contract schedule. Shipments are made to Bosnia and Herzegovina by sea, with logistics tracking maintained to ensure timely delivery to the project site.
2. On-site Installation Coordination: English installation drawings are provided to resolve technical issues during installation, ensuring precise connection between the valves and the water supply pipeline.
1. Project Results: All DIN standard ductile iron hard-seal gate valves were installed and put into use, adapting to the urban water supply pipeline conditions in Bosnia and Herzegovina. They offer flexible opening and closing, zero leakage, excellent freeze and corrosion resistance, effectively solving leakage problems in aging pipelines, improving water supply efficiency and stability, and contributing to the successful completion of local public water supply projects.
2. Customer Feedback: The customer highly recognized the quality, delivery efficiency, and technical service of Yuming Valves' DIN standard products. They commented that the products fully comply with DIN standards, are compatible with European water supply networks, and offer stable hard-seal performance and long service life, far exceeding expectations.
