Zirconia is mainly composed of zirconium dioxide. At room temperature, it is a material with high mechanical strength and strong fracture toughness in all major advanced ceramics. It can be used to manufacture cutting blades, scissors and knives. With it’s excellent surface smoothness, the material is also widely used in pump valve components, electronics, wearables decoration components.

Zirconia ceramics are further processed into various zirconia ceramic parts, disc valve is one of them, although the metal disc valve after the improvement of structure and materials, has been greatly improved, but limited by the characteristics of metal materials, can not adapt to the needs of more and more high wear, strong corrosion and other harsh conditions, and then show short service life, serious leakage and other problems. The stability of system operation is greatly affected.
After using zirconia ceramic disc valve instead of disc valve, the above series of problems have been properly solved, that is because the thermal deformation of ceramic material is very small, light weight, and has much higher bonding strength than metal, excellent corrosion resistance, so it can better adapt to high wear, strong corrosion and other harsh conditions.
 Good Surface Finish |
 High Fracture Toughness |
 High Mechanical Strength |
 Excellent Wear Resistance |
In addition, grinding processing technology has also improved, making zirconia ceramic disc valve can be better formed, and the product is more widely used in petroleum, chemical, machinery and other fields, becoming one of the ideal substitutes for traditional metal water valve plate.
