High-purity material: The base material is high-purity zirconia ceramic (ZrO₂), which is milky white in its pure state and appears light yellow after the addition of modified rare earth materials.
Precision machining: The surface finish reaches W2 grade (ultra-precision machining standard), and the sphericity of the sphere is strictly controlled.
Mechanical properties: Rockwell hardness reaches HRA88 or higher, bending strength exceeds 800MPa, and compressive strength exceeds 3000MPa.
Ⅰ.Zirconia Ceramic Valve Core Sleeve Product Introduction:
Zirconia ceramic valve core sleeves are critical components in valves, made from high-performance zirconia ceramic (ZrO₂). They are widely used in industrial valve applications, particularly in fluid control scenarios under demanding operating conditions. The core material boasts high purity, high hardness, and excellent chemical stability, meeting the requirements of harsh industrial environments.
Ⅱ.Core Advantages
Ultra-long service life: Under harsh working conditions (such as high pressure, high-speed fluid flow, and particle erosion), the valve can withstand up to 10,000 switching cycles without leakage.
Excellent corrosion resistance: It exhibits excellent resistance to acidic and alkaline media such as sulfuric acid, hydrochloric acid, and nitric acid, as well as salt solutions (except hydrofluoric acid and glass solutions).
Superior sealing performance: Achieves "zero leakage" sealing effect, and the low torque design reduces operating torque.
High-temperature stability: Suitable for most industrial high-temperature applications, maintaining dimensional stability even in high-pressure, high-temperature fluid environments.
Ⅲ.Application Fields
Zirconia ceramic valve cores are widely used in industrial applications requiring stringent sealing, corrosion resistance, and wear resistance:
Energy and Power: Boiler steam pipelines, flue gas desulfurization (FGD) systems, and ash and slag removal devices in thermal power plants.
Chemical and Metallurgy: Acid, alkali, and salt media transfer valves in petroleum refining and chemical reactors, and slurry control valves for media containing particles/fibers.
Water Control Systems: Household and commercial faucets and pump systems.
High-Temperature Environments: Hot water systems and high-temperature fluid handling.
Precision Equipment: Fluid control in medical equipment and precision laboratory equipment.
