德国LOCKE洛克进口电动陶瓷调节阀采用三段式结构，其主要由陶瓷球阀与电子式电动执行机构组合而成，根据不同的现场工况运用不同的锻件材质（碳钢或不锈钢），使阀体材质的结构更加合理。阀门内部材质与介质接触部分均采用结构陶瓷材料，避免与介质直接接触，而产生腐蚀的可能。结构陶瓷化学性能稳定，硬度高，可耐绝大部分酸碱介质腐蚀，并且具有极好的耐磨性能。广泛应用于电厂的烟气脱硫系统、除渣系统以及燃烧系统；碱厂的盐水系统、蒸馏系统；造纸厂的纸浆控制系统等。尤其是在电站脱硫（FGD）工程中，陶瓷阀很好地解决了FGD工况存在的高氯离子腐蚀，高固含量磨损两大问题。在石灰石浆液、石膏浆液废水的调节过程中德国LOCKE洛克进口陶瓷调节阀是目前最理想的阀门。

Germany locke imported electric ceramic control valve adopts three-stage structure, which is mainly composed of ceramic ball valve and electronic electric actuator. According to different field conditions, different forging materials (carbon steel or stainless steel) are used to make the structure of valve body material more reasonable. The internal material of the valve and the contact part of the medium are made of structural ceramic material, so as to avoid the possibility of direct contact with the medium and produce corrosion. The structural ceramics have stable chemical properties, high hardness, corrosion resistance in most acid and alkali media, and excellent wear resistance. It is widely used in flue gas desulfurization system, slag removal system and combustion system of power plant, brine system and distillation system of alkali plant, pulp control system of paper mill, etc. Especially in the FGD project, the ceramic valve can solve the two problems of high chloride ion corrosion and high solid content wear. In the regulation process of limestone slurry and gypsum slurry wastewater, the ceramic control valve imported from Germany Locke is the most ideal valve at present.

1. Light weight, beautiful appearance. It is about 80% lighter than the traditional leading products of single seat valve, double seat valve and sleeve valve; it is 45-55% lighter than the Japanese fine and small control valve which did not appear in 1980s.

2. In terms of function, it can replace many products with incomplete functions, simplify the modeling, and solve the shortcomings of complex factory management, complex selection and heavy maintenance workload. A kind of

3. The adjustable ratio of the valve is large, generally up to 100, and from 10% to 90% of the opening can ensure good regulation.

4. It has stable operation and high reliability, which can solve the fatal structural defect of traditional valve with large leakage.

5. With excellent on-off characteristics and zero leakage, the fatal structural defect of traditional valve with large leakage is solved.

6. Good ability to overcome pressure difference, anti blocking function, the simplest flow path, no resistance regulation, maximum Kv value, and the best self-cleaning performance.

7. The flow characteristic of the control valve is approximately equal percentage (see the figure below for the comparison between the ideal flow characteristics and the standard equal percentage characteristics). However, due to the pressure difference between the front and back of the valve, the actual curve of the traditional control valve will have a great distortion, but also relatively small, so it not only has good regulation performance, but also has good economy and energy saving.

8. Electric ceramic control valve and pneumatic ceramic control valve can be used according to the needs of users

9. According to the actual use environment, PTFE lined ceramic ball valve or fully lined ceramic hard seal ball valve can be used to obtain higher corrosion resistance and resistance.

All parts in contact with the medium of imported ceramic control valve are made of structural ceramic materials, and its chemical stability and hardness are very high (Rockwell hardness hrc90), second only to diamond. Therefore, the valve has very high wear resistance, corrosion resistance, erosion resistance, and good thermal insulation, small thermal expansion.

The imported ceramic regulating valve ball is manufactured by advanced grinding equipment and technology, with high roundness precision and good surface quality. After lapping with the ceramic valve seat and using the self lubrication property of Zr02 ceramics, good sealing performance can be achieved, which can truly achieve the good hard seal between ceramics and ceramics.

Imported ceramic control valve completely changes the metal hard seal ball valve easy to leak, high torque, sealing surface is not resistant to corrosion and wear.

The good wear resistance of the imported ceramic control valve makes the valve durable, highly reliable and has a long service life, which is 2-4 times of that of titanium alloy valve and Monel valve.

The imported ceramic control valve is used in the medium with high hardness, or medium with soft particles but corrosion. This valve has incomparable absolute advantages and is the only valve suitable for such medium at present.
