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.
Customized valve core flow curves, opening and closing torques, and sealing structures for different scenarios such as household bathroom valves (toilet, shower, basin valves), industrial pipeline valves, commercial water purification valves, and wall-hung boiler valves. The tactile damping is optimized to achieve "light turning for precise temperature control".
Offers a variety of material combinations including brass, stainless steel (304/316), ceramic, and engineering plastics (POM/PTFE). For food-grade applications, 316 stainless steel is preferred. For high-temperature applications, ceramic sealing plates offer more than 3 times the wear resistance of traditional materials.
Supports personalized adjustments such as valve core diameter (Φ5–Φ50mm), interface type (thread/clamp/welded), opening angle (90°/180°/custom), and sealing level (IP65+). Our engineering team ensures perfect compatibility with your existing valve body through reverse modeling.
The reliability of the valve core stems from stringent production control and performance testing through our full-chain quality inspection system.
All metal materials are tested by spectroscopy. Ceramic sheets use high-purity alumina sintered at 1700℃. Seals are made of food-grade silicone or EPDM rubber.
Using CNC lathes and five-axis machining centers, accuracy is controlled within ±0.005mm, ensuring smooth opening and closing without jamming.
Each batch undergoes 12 tests: sealing (no leakage under 10 bar), life test (500,000+ cycles), salt spray corrosion, and temperature shock.
