Ø50 Ceramic Valve Ball In Material Of Zirconia With High Precision
Description of Ø50 Ceramic Valve Ball:
Our zirconia valve balls are made by highly purified, sub-micron and after Y2O3 partially stabled zirconia powder material and are processed by AP (Atmospheric Pressure) sintering and HIP (Hot Isostatic Pressure) sintering technology, so their porosity, wear resistance, impact resistance and resistance to fatigue contact life are greatly improved. Our company has professional forming, sintering and grinding technology to manufacture the zirconia valve balls of large size, our ceramic valve balls are acclaimed.
