Valve industry around the world appears many new development direction, should cause the attention of the relevant aspects, such as manufacturers and users.

1. Is committed to the standardization of products

Product standardization is to realize the modernization of production and product supporting each other, the basis of countries always values. But because there are many different kinds of valve products and the characteristics of the widely used, its standardization pace is very slow, can't keep up with the demand of the development.

Into the 80 s, countries are working in importance to the formulation and revision of the standard, so as to adapt to the industrial sector continuously put forward new demands and the continuous expansion of international trade. Valve has more influence on international standard system in addition to the lSO standard, and the American ASME, API, ANSI, MSS and ASTM standards, the German DIN standards, Japan's JIS standard, British BS standard and standard of FN (France).

2. The valve to further expand international trade

Although including the organization of petroleum exporting countries, Latin America, Africa and eastern Europe, most of the valve trade opportunities in developing countries are greatly reduced, but in the late 80 s to 80 s international trade or valve developed on a large scale. East and southeast Asia the valve to the rapid growth of the import and export of North America and the European Union and other developed countries asked the sustainable development of the mutual trade and contribute to the expanding of the international trade in the valve. Germany, Italy, Japan and Taiwan province of China and other countries and regions to expand exports, and the United States, Britain, France and other imported high-speed growth, to form the strong point of the international valve trade prosperity.

3. The environmental protection become a focal point of the development of new and high technology valve

With the increasing of human environmental protection consciousness, more than a decade of updated valve industry put forward higher requirements. The United States, Japan, Germany and other countries in recent years many of the valve manufacturer committed to new product development for environmental protection valve, they think it is a lucrative new market. The valve has three main reasons that cause environmental pollution. First, is toxic and radioactive medium by sealing leakage incident to the outside world. Second, the relief valve is emptying or gas liquid medium through the throttle body produce noise pollution. Third, foot or water supply system using the diet industry contains lead, zinc, calcium and other harmful elements manufacture pipe and valve is easy to damage to the transmission medium, thus endanger human body health.

In the 80 s, countries have developed a pure graphite packing and vigorously promote the bellows seal valves. Thus greatly improve the valve seal can be *, effectively prevent the leakage of toxic medium. At the same time using multi-stage decompression and new structure of hierarchical decomposition of the jet valve, to reduce or eliminate noise. According to the valve manufacturers association, the United States of valve in the water supply system using the content of lead, zinc, calcium is reduced. Japan's water supply system has more use of the stainless steel valves and plastic coating valve. Have legislation to effectively protect the environment, Germany, in 1994 to prohibit use of asbestos materials on the valve packing or gaskets, etc.

4. New materials used in the valve industry

The rapid development of new technology, has made it possible to all kinds of engineering materials used in valve manufacturing. Valve material has already been not the concept of traditional metal and nonmetal materials. Now as the valve material except inorganic materials, have begun to use organic materials and synthetic materials. In recent years, the use of new materials has developed a large number of high performance valve new products:

Plastic valve, it is made of engineering plastics instead of metal valve. Is better than stainless steel or copper valve lower cost and easy to manufacture and has the characteristics of rust corrosion. Has developed varieties of plastic valve gate valve, diaphragm valve, check valve, ball valve, butterfly valve, etc.

Ceramic valve, used to make the valve or valve components of precision ceramics with high strength, corrosion resistance, wear resistance and electrical insulation, etc. The valve using ceramic valves can be use temperature from 400 ℃ to 400 ℃ or more. Using the ceramic manufacturing control valve throttling components, can make its exponentially increase service life.

Composite material valve, valve parts, manufactured by means of carbon fiber composite materials have high strength, light weight, corrosion resistance, etc.

Memories of the valve, the use of shape memory alloy or warm memory alloy reversibility and high elastic manufacturing valves can be used to replace the thermostat, not frozen water hydrant and fire safety valve.

Titanium valve, because of the pure titanium and titanium sponge casting technology already pass, titanium valve to get long-term development. Titanium valve has the advantages of light weight and corrosion resistance were used in the aerospace industry and nuclear industry, in recent years the development of titanium and titanium alloy valve, on the basis of improving performance, greatly reduced the cost, make its application prospect.

5. The valve industry widely used computer technology

Valve valve industry abroad, in addition to computer aided design (CAD) outside the wide application of computer aided manufacturing (CAM), valves (CAPP) has been a large number of applications. The valve industry has developed a flexible manufacturing system used in the valve industry, that gives a wide variety, model complex valve products for mass production.
