Chinese Valve Production has Over 2.6 Million Tons from January to May in 2012

In recent years, Chinese valve industry has entered a period of rapid development, has become Asia's largest valve machining center, one of the world's largest valve market. The monitoring data shows from January to May in 2012, the valve output reached 2.629 million tons in China, it has an increase of 14.64%. In May, the chinese production of valves 609,300 tons, an increase of 7.40%.

From the production point of view of provinces and cities, from January to May in 2012, the largest valome of our chinese valve production comes from three provinces and cities in Zhejiang Province, Henan Province and Jiangsu Province, respectively, accounting for 28.88% of the total output, 22.36% and 13.88%.

The per capita consumption level of our valve products in the world and not high, currently only $ 22 per capita. With the development of the valve industry in China, the varieties of valves are constantly more and more, the application of the valve industry, such as the petrochemical industry, oil refining industry, nuclear industry, thermal power industry has widely used, indicating that the prospects broad market attractive.

The Competition Analysis of Chinese Valve Industry in 2011-2012

Global valve manufacturing focused on the economically developed regions of North America, Europe and Asia, Japan, China and other regions. Ranked global valve manufacturing industry, the top five were: the United States, Japan, Germany, China and the United Kingdom. Among them, the U.S., Europe and Japan and other developed countries and regions, mainly in the metallurgical, petrochemical, nuclear power valve, lower production and sales ratio to the drain valve. In recent years, demand-pull impact to the drainage valve market faster growth areas, including China, India and other countries, including East and Southeast Asia. Domestic point of view, our valve business volume highest in the world, but at the same time, the domestic to the overall size of the drainage valve business too small, industry concentration is not high, the size and financial strength is difficult to compete with large foreign companies. Valve Branch of China General Machinery Industry Association statistics show that in the first half of 2009, as of the end of June 2009, the main business of the semi-annual sales volume of China's major water supply and drainage valve business in 300 million yuan.

An Outlook for the Development of Water Drainage Valve in 2012-2013

(1) market overall demand continued to maintain steady growth

Mechanical processing and manufacturing, to the water valve manufacturing industry and its market development is mainly affected by the stimulating effects of the downstream application market. According to statistics of China General Machinery Industry Association, the world's total demand for the types of valves, industrial valves, including about $ 60 billion, of which approximately $ 6.84 billion to the water valve. With the growing demand of developing countries on the control valve, and environmental protection valve, to the water valve industry is expected to remain stable growth.

From the perspective of the domestic situation, the infrastructure is the focus of China's economic construction, water supply and drainage in size, since the global economic crisis, the state increase its infrastructure investment, water treatment equipment manufacturing industry has been formed, including water supply and drainage valves water industry, provide a huge space for development of the drainage valve industry.

(2) large diameter, large diameter valve market, domestic production capacity, market demand

With the constantly increasing rate of urbanization in China, urban population growth, the scale of the supply quantity of the water plant and sewage treatment plants and sewage treatment is to gradually increase the caliber of the pipe network is increasing and therefore require a large number of various types of large diameter, large diameter drain valve door. At the same time, into the water conservancy construction and management of various types of flood control, drainage, irrigation, water supply and drainage, hydroelectric power, water and soil conservation, water conservation and other works of construction is very strong demand for all types of large diameter, large diameter water supply and drainage valves, resulting in At present, large-caliber and large caliber to the drain valve capacity production can not meet the downstream market demand growth. The next few years, China continues to accelerate the implementation of comprehensive management of a new three projects of the Huaihe River and Taihu Lake, Dongting Lake, Poyang Lake, and promote key sections governance of Ningxia and Inner Mongolia reaches of the Yellow River, Yangtze River middle and lower reaches of the river regime control major rivers, "South Water Transfer to North” project of the century the launching of the project will continue to boost the scale of demand for products of various types of valves, especially in large diameter valve, large triple offset butterfly valve, large diameter turbine inlet valve, large diameter flow control valve and the varieties of the large diameter vacuum valve. Due to the large diameter and large diameter valve production on the technical and technological requirements to be much higher than normal valves, a single product with higher added value, a higher demand this level of product design and processing level.

Currently, only some of domestic enterprises can meet the requirements for technology and equipment, most of the other companies in the industry to the production of normal small diameter valves, from the entire industry, the production of large diameter water supply and drainage valves production will appear in a steady growth trend. According to take intermediate values ​​between the valve Branch of China General Machinery Industry Association statistics, large diameter and large diameter valves in the field of water supply and drainage, the share of sales accounted for approximately 50% to 60%, 55%, from 2009 to 2011 The size of the market was 82.4 billion yuan, 9.55 billion yuan and 10.58 billion yuan.
