As the "heart" component of a water valve system, the performance of the valve core directly determines the valve's sealing performance, durability, and operational precision. We have deep expertise in the field of customized hardware components, focusing on the research and development and production of water valve cores. With "precise fit, superior quality, and customization to your needs" as our core principles, we provide cost-effective valve core solutions for customers in various industries, including sanitary ware, HVAC, water conservancy projects, and home appliances, helping to enhance the competitiveness of their end products.
The reliability of the valve core stems from stringent production control and performance testing. We have established a full-chain quality inspection system from raw materials to processing to finished products, ensuring that every batch of valve cores can withstand long-term use.
All metal materials are tested by spectroscopy to ensure that the composition meets the standards; the ceramic sheet is made of high-purity alumina ceramic, sintered at 1700°C, with a surface finish of Ra0.1μm; seals are made of food-grade silicone or EPDM rubber (-20°C to 120°C).
Using CNC lathes and five-axis machining centers, accuracy of key parts is controlled within ±0.005mm, ensuring smooth opening and closing without jamming; automated assembly lines improve product consistency.
Each batch must pass 12 core tests: sealing test (10 bar/30 min), life test (500,000+ cycles), corrosion resistance (48h salt spray), and temperature shock test before shipment.
