What is Ceramic Ball Valve ?
The internal ball of ceramic ball valve components are toughened alumina or zirconia, its chemical stability and hardness is very high, with very high wear resistance, corrosion resistance, erosion resistance, and good thermal insulation, thermal expansion coefficient is small, high hardness and high thermal insulation, performance is better than other materials. The ball of ceramic ball valve with its unique design principle and material advantages, in a variety of working conditions have shown excellent stability and durability. Whether in extreme temperatures, corrosive environments or fluids containing solid particles, ceramic ball provides reliable service.
Advantages of ceramic ball valve
- 01Ceramic ball valves use high-tech new materials (alumina, zirconium oxide) as seals.
- 02Corrosion-resistant, erosion-resistant, and not easy to wear.
- 03Built-in buffer compensation elastic gaskets ensure stable and good sealing. And in the medium containing impurities, it is not easy to get stuck and cause the ball to break.
- 04Ceramics have high compressive strength, high wear resistance, excellent oxidation resistance and corrosion resistance, high temperature resistance, and good thermal insulation performance.
- 05The ball has high roundness. After grinding with the valve seat, the self-lubricating property of structural ceramics is used, the opening and closing torque is small, and it has excellent sealing performance.
- 06The flow channel and the middle body are fully lined with structural ceramics, which can effectively avoid the erosion of the flow channel and the valve body due to high flow rate and high solid content.

| The characteristics of ceramic ball valve |
All parts in contact with the medium are made of structural ceramic materials, and their chemical stability and hardness (Rockwell hardness HRC90) are second only to diamond. Therefore, this valve has excellent wear resistance, corrosion resistance, erosion resistance, good heat insulation and small thermal expansion. The ball is manufactured using advanced grinding equipment and technology, with high ball roundness accuracy and good surface quality. After grinding with the valve seat, the self-lubricating property of Zr02 ceramics can be used to achieve good sealing performance. The good wear resistance of ceramics makes this valve durable and very stable. It is 2-4 times more durable than titanium valves and monel valves. This type of valve has incomparable advantages in high-toughness granular media, or media with soft particles but corrosive, and is also suitable for such media. |
