Recently, Hunan Yuanhong New Materials Co., Ltd. releases standardized and custom alumina ceramic water valve discs, supplying precision ceramic sealing components for global faucet, water purifier and industrial fluid control valve manufacturers.

Alumina water valve disc is the core friction-sealing part inside valve cartridges. It is commonly made of 95% or 99% high-purity alumina powder, manufactured via dry pressing, high-temperature sintering, surface grinding and mirror polishing. Featuring excellent flatness, low porosity and ultra-smooth mating surfaces, our ceramic discs achieve low friction, zero leakage and good resistance to limescale buildup. Compared with metal and plastic seals, alumina ceramic delivers superior hardness, acid & alkali corrosion resistance and stable performance under hot-cold cycling. It can withstand hundreds of thousands of on-off cycles, greatly reducing leakage, sticking failure and maintenance cost of valves.

With in-house mold workshop, precision machining and full-process quality control, Yuanhong accepts custom designs based on customer drawings or samples. We can adjust outer diameter, thickness, flow hole pattern and locating structure, supporting both mass production of standard sizes and non-standard OEM development. Our discs are widely used in kitchen & bathroom faucets, thermostatic cartridges, water filters, water treatment equipment and small pump valves, suitable for cold water, hot water, chlorinated water and mildly corrosive media.

Hunan Yuanhong New Materials has long specialized in advanced precision ceramics. We focus on R&D and production of alumina and zirconia structural ceramic parts. We guarantee stable lead time, traceable inspection documents and professional technical support for overseas partners. Global buyers, cartridge factories and sanitary brands are welcome to contact us for samples and bulk orders.
