1. The medium contains impurities, resulting in the ball valve being stuck;
2. There is a problem with the sealing surface of the ball valve (deformation, etc.).
The above are common causes, please check them one by one.

Ceramic Ball ValvesCeramic ball valves are widely used in power plant desulfurization systems, washing and dressing systems, fluid flow control systems, chemical industries and other strong corrosion occasions.
It has the following performance characteristics:
1. Adopt domestic advanced production technology, with extremely high precision.
2. It is formed by cold isostatic pressing, sintering at high temperature and precision machining;
3. The parts have good compactness, high size and shape accuracy;
4. The sphere is manufactured by advanced grinding equipment and technology, with high roundness and precision, and the surface is high.
5. It adopts high-performance zirconia ceramic material, which has superior performance.
6. The ball core and valve seat are made of zirconia engineering ceramics, with small friction coefficient and reliable sealing;
7. All parts in contact with the medium are structural ceramic materials, with extremely high chemical stability and hardness (Rockwell hardness HRC90);
8. High mechanical strength, high wear resistance, corrosion resistance, erosion resistance, good heat insulation, and small thermal expansion.

Ceramic ball valves are widely used in power plant desulfurization systems, washing and dressing systems, fluid flow control systems, chemical industries and other strong corrosion occasions.
It has the following characteristics:
1. All parts in contact with the medium are structural ceramic materials, and their chemical stability and hardness are extremely high (Rockwell hardness HRC90), second only to diamond. Therefore, the valve has extremely high resistance to wear, corrosion and erosion, and has good thermal insulation and low thermal expansion.
2. The ball is manufactured by advanced grinding equipment and technology, with high spherical roundness accuracy, excellent surface, and after grinding with the valve seat, the self-sliding wettability of ZR02 ceramic can be used to achieve good sealing performance.
3. It has completely changed the shortcomings of metal hard seal ball valve that are easy to leak, large torque, and the sealing surface is not corrosion-resistant.
4. The good wear resistance of ceramics makes this valve durable and highly reliable. Long service life, 2-4 times that of titanium alloy valves and Monel valves.
5. Used for high hardness granular media, or soft particles but corrosive media, this kind of valve has incomparable absolute advantages, and it is also the only valve suitable for this kind of medium.

It is suitable for any medium except hydrofluoric acid and glass solution, and the temperature can reach 500 degrees Celsius, and the maximum pressure is high corrosion, high wear, high temperature medium. All the parts of the medium contact are structural ceramics, its chemical stability and hardness are extremely high (Rockwell hardness HRC90), second only to diamond, therefore, this valve has extremely high wear resistance, corrosion resistance, erosion resistance, and good thermal insulation performance, small thermal expansion, high hardness of granular medium or soft particles but corrosive medium, this valve has incomparable absolute advantages, is the only valve suitable for this kind of medium, has been widely used in power plant desulfurization system, slag removal system and combustion system, In the distillation process of the alkali plant and the pulp system of the paper mill, the ball is manufactured by advanced grinding equipment and technology, the roundness accuracy of the ball, the surface is high, and the self-lubrication of ZRO2 ceramic can be used to achieve good sealing performance after the research with the valve seat, which completely changes the shortcomings of the metal hard seal ball valve that is easy to leak, large torque, and the sealing surface is not resistant to corrosion and wear.

These two kinds of valves are not a category, it is not easy to compare, ceramic valves mostly refer to ceramic ball valves, mainly used in high-temperature environments, ordinary ball valves use the ambient temperature below 180 degrees.
-
The question you are asking is not correct. There are also different types of ceramic valves.
-
Whether you can use a ceramic ball valve, you also need to look at the pressure and the specific situation of the medium, only the temperature, part of the medium can not be judged, for example, if there is HF acid, you can not use the ceramic ball valve, if it is under normal pressure conditions, the medium should not contain water vapor. Ceramic ball valve is more suitable for high corrosion, strong wear and tear conditions, and can better reflect the high cost performance of the product! Such as scarring, crystallization, slurry, slurry, etc.
Ceramic ball valve still has a certain technical content, the current situation on the market is mixed, it is recommended to choose, more investigation, choose a professional manufacturer to buy!

Wenzhou Yiduo ceramic valve **** specializing in the production and manufacture of ceramic valves, ceramic ball valves, double gate valves, etc., has superior technical capabilities, ceramic ball valves are used in wear-resistant and corrosion-resistant working conditions, used in petroleum, chemical, metallurgy, thermal power generation, mining, aluminum, coal, papermaking and other high wear and strong corrosion conditions, to ensure safe production, purify the environment, industrial automation, energy conservation and other aspects play an important role.

This question is very dangerous to answer, if you don't get it right, you will be suspected of advertising ingredients, simply say that the ceramic ball valve which production is more professional, I believe that as long as the country can produce ceramic ball valve factories should be more professional, not professional will not be able to produce it. I work in Shanghai Industrial Comprehensive Development Zone, we do testing equipment, I bought a few ceramic ball valves before, and Shanghai Yiling Industrial **** in the development zone bought, close to the company, after-sales do not have to be afraid, I feel that this thing is very expensive, much more expensive than ordinary stainless steel ball valves, wear-resistant is quite wear-resistant, not much broken.

Specific national standards You refer to it.

The former has higher strength and a denser internal structure, which can reach a Rockwell hardness of 85-90, and the latter is also about 80, and the reason for densification is also because of isostatic pressure treatment; In the early stage of ceramic ball valves, there is a billet sintering stage of ceramic parts, and then rough machining.
The processing of parts and components is mainly for turning and grinding, grinding is also the same grinding ball machine as the wear-resistant ball valve for grinding, spherical grinding is determined according to the size of the margin left after rough machining, generally between an hour and three hours, to reach a certain processing accuracy (not the garden) after assembly, we used to produce products are mainly six-piece sets, and there are also four-piece or three-piece sets, (in the previous two years of the valve exhibition compared with the products produced by similar manufacturers, Our valve ball and seat ring are completely adhered to the self-sliding wettability, so as to achieve zero leakage, which shows that our grinding accuracy is superior) Our quality level is also in the forefront of similar products in China.
