Characteristics and Applications of Ceramic Valves

In harsh environments such as chemical, coal, and petroleum, traditional metal valves can no longer meet the needs of high wear and strong corrosion conditions. Metal valves are prone to leakage, high torque, and poor corrosion resistance of sealing surfaces, which not only affect production efficiency but also pose safety hazards.

The emergence of ceramic valves provides a new solution for pipeline control in harsh environments. Ceramic valves are made of high-performance structural ceramics and have the following characteristics:

1. The hardness of ceramics is second only to diamond, with high wear resistance, dozens of times that of metal materials.

2. Ceramics have good chemical stability and can resist most corrosive media such as acids, alkalis, and salts.

3. Ceramics have a low coefficient of friction, good self-lubricating properties, and are not easily stuck.

4. Ceramics have a high melting point and can withstand high-temperature media.

5. The lifespan of ceramic valves is several times or even tens of times that of metal valves.

So what are the applications of ceramic valves?

At present, ceramic valves are widely used in industries such as chemical, petroleum, coal, metallurgy, and power, for transporting corrosive media such as high-temperature molten metal, desulfurization slurry, coal slurry, sulfuric acid, hydrochloric acid, nitric acid, sodium hydroxide, potassium hydroxide, etc.
