Pneumatic Ceramic Ball Valve
TOT Valve Pneumatic ceramic ball valve is a control valve designed for high wear and high corrosion conditions, because we use high-quality alumina ceramic (Al₂O₃) or zirconium oxide ceramic (ZrO₂) as the material of the ball and valve seat.
If you are applied to the conveying system of high-hardness particles and highly corrosive media in thermal power plants, mining, metallurgy, chemical industry, coal chemical industry and other industries, then our pneumatic ceramic ball valve will be your ideal choice.

Pneumatic Ceramic Ball Valve Performance Advantages
Extremely Strong Wear Resistance: high ceramic hardness (Vickers hardness up to HRA 88 or above), greatly extending the service life
Strong Corrosion Resistance: suitable for harsh media such as acid, alkali, salt spray, etc.
Quick Opening and Closing: pneumatic operation, suitable for frequent opening and closing conditions
Long Service Life: ceramic internals are 3-5 times longer than ordinary metal valves, or even higher
Wide Application Areas: thermal power plant desulfurization system (lime slurry, gypsum slurry), coal powder conveying system, pneumatic conveying system, high-temperature granular material cutting in the metallurgical industry, chemical corrosive acid and alkali liquid conveying
