Metallic materials, polymeric composites, ceramic materials are listed as three contemporary solid materials, among which the advanced ceramics representing the new materials in the 21st century, namely high-tech materials will be more widely applied in industry. The ceramic valve is the outstanding results of this application.

At present, the valve commonly used in our China’s industries is the metal valve, whose use has a history of more than 100 years. Although it is improved in structure and materials, due to their limited metal, metal corrosion and damage have a considerable effect on the valve wear, reliability and service life. For the mechanic and corrosion factors, the metal surface is increasingly worn. In operation, the friction surface is worn and damaged because of the interaction of the mechanical, chemical or electrochemical effects between metals and environment. On the valve, the pipeline work and the natural climate are complex; the appearance of the hydrogen sulfide, carbon dioxide and some organic acids in the medium such as oil, gas and oil water increases the destructive power of the surface and rapidly loses the ability to work.

The chemical corrosion of the metal are mainly in: temperature, friction and mechanical load of parts, lubrication materials contained in the sulfide and acid stability, medium duration and the course of the catalytic metal nitride, conversion speed of the molecular of the corrosion or erosion substances on the metal. For these irreversible factors, the use of metal valves was once in the "embarrassing" state, while metal valve corrosion measures also are affected by the demand for the term of protection, transport and storage conditions, the valve construction features and materials.

Metal valve can not meet the demand of poor working condition of the power, petroleum, chemical, metallurgy, mining, sewage treatment and others which are high wear and can’t be strong corrosive. Meanwhile, the short life, serious leak greatly affect the system stability. We must seek a kind of new material to replace metal, especially in the condition that the traditional metal valves need to be completely innovated in materials, design and manufacturing technology. Therefore, it has become one of the subjects researched by valve industry to seek the antisepsis and measures.

The researchers in Yantai Mingzhu Valve Co., Ltd. successfully research and develop the valve both with the metal valve wear and good corrosion of synthetic materials.

Characteristics of ceramic materials are very small deformation, higher and more bond strength than the metal. Generally, the crystal ion composed of ceramic materials has a small radius and price of ion is high and bits are large, which decide that the tensile and compressive strength, modulus of elasticity, and hardness of ceramic materials are all very high. However, the ‘softness’ and its difficult to process of ceramic limit its application range. In recent decades, as the development and improvement of the martensitic transformation toughening technology, composition materials technology and nano-ceramic, the "brittleness" of the ceramic has been greatly improved. Its strength and toughness have been greatly improved and application range has been expanded.

MZ ceramic valves are mainly used in electric power, petroleum, chemical, metallurgy, mining, sewage treatment and other industrial fields. The superior functions can be demonstrated especially under the high wear, high corrosion, high temperature, high pressure and other poor working conditions. MZ ceramic ball valve can meet the following characteristics: firstly, the high-tech ceramic structure materials are adopted to make the sealing parts and vulnerable parts, which improves the wear resistance, corrosion protection and sealing, and greatly extends the use life of valve. Secondly, the use of ceramic valves can significantly reduce the number of valve maintenance and replacement, improve security and stability of operating system of the ancillary equipments, reduce labor intensity and save equipment repair costs. Moreover, the use of MZ ceramic valves can increase the tightness of industrial piping systems and prevent the disclosure at the maximum, which will play an important role in the promotion of environmental protection. Finally, there is a wide range of ceramic raw materials and low cost. We can produce superior ceramic materials by the common components such as aluminum, carbon and silicon to save a lot of metal materials and rare mineral resources. With its superior performance, MZ ceramic valve has been recognized by more and more people in the industry. Welcome friends to visit our company and negotiate business.
