Bearing Si3n4 Silicon Nitride Ceramic Ball Control Valve 25mm
Ø25 Ceramic Valve Ball In Material Of Silicon Carbide With High Precision
Description of Ø25 Ceramic Valve Ball:
SSiC valve balls are made of highly purified, sub-micron silicon carbide material. We sintered the silicon caibide with pressureless sintering method, so SSiC material have well corrosion resistance, high strengthm high hardness, wear resistance and small friction coefficient, antioxidant, small creep high temperature and good heat stability.
Main application of silicon carbide valve ball:
Because of our material and producing advantages, our silicon carbide valve balls are widely use in metering pump and other pumps and play a good role in preventing leakage.
