At present, metal valves are commonly used in the production of various industries, and metal valves have been used for hundreds of years. Although through the continuous improvement of structure and materials, the metal valve is restricted by the metal material conditions, and can not adapt to the needs of high wear, strong corrosion and other harsh conditions.It is mainly reflected in short service life and serious leakage, which greatly affects the stability of system operation.Traditional metal valves are in urgent need of innovation in materials, design and manufacturing process.Ceramic material, as a new kind of wear-resisting and corrosion-resistant material, has been paid more and more attention by more and more workers. it is applied to industrial valve,which is scientific and technological innovation.

Compared with metal materials, ceramic materials have a high hardness, in recent years, due to the development and progress of Maherandi and hardening technology, composite materials and nano-ceramics, its toughness and strength has been greatly improved, the application of ceramic materials has been expanding.

In recent years, the application of ceramic materials is very active in petroleum, chemical industry, machinery , the using ceramic wear resistance, corrosion resistance instead of metal materials to produce wear-resistant, corrosion resistant parts ,which is one of the important development direction of high-tech materials market.At present, FREE-VALVE’s ceramic valve products mainly include pneumatic ceramic swing disc gate valve, ceramic double disc gate valve, ceramic knife gate valve, ceramic butterfly valve, ceramic ball valve and ceramic pipe fittings, etc., they have the following advantages:
1. The using ceramic materials to produce valve sealing parts and consumables, which improve the wear resistance of valve products, corrosion resistance and sealing, extend the service life of the valve.
2. The using of ceramic valves can greatly reduce the number of valve maintenance, replacement, improve the reliability of supporting equipment operating system, stability, reduce the labor intensity of workers, save equipment maintenance costs.
3. There are a wide range of raw materials for making ceramics, with aluminum, carbon, silicon and other common elements can be used to create superior performance of ceramic materials, can save a lot of metal materials and rare mineral resources.

In a word,FREE-VALVE’s ceramic valves are mainly used in coal power station, petrochemical, sewage treatment and other fields, especially in the face of high wear, strong corrosion and other harsh conditions, but also show its excellent performance, cost-effective far better than other similar metal valves. With the continuous development and progress of science and technology, ceramic materials in the formulation, molding, processing and assembly technology more mature and complete, ceramic valves with its excellent performance more and more recognized by the industry.
