Ceramic ball valve of zirconia/silicon carbide with high precision
Description of Ceramic Ball Valve:
The ball valve has tha advantage of large contact area, tight seal, and less leakage, etc. It can be divided two kinds: floating type and stationary type.
Main applications of Ceramic Ball Valve:
1. The ball valve mainly transmits strong corrosive material, such as acid, alkali, salt and so on.
2. The ball valve is maily used for transmitting high wear-resisting material, such as silicon powder, coal dust and so on.
