China's valve industry in the industrial structure, the valve industry, the industrial chain, and the degree of specialization and trade were with foreign enterprises exist big gap caused by poor quality of domestic valve products is: the rapid expansion of the market, the original state valve companies have shut down and turn, although a number of Township enterprises developed rapidly, but because of the low starting point of township enterprises, technical force is very weak, poorly equipped, most products are produced to imitate, especially the low pressure water supply and drainage valves serious but the problem does not affect the future of China's valve industry and broad prospects. This is mainly due to the national policy support and valve product market strong demand for, especially several century project "west east gas transmission", "power transmission from west to East", "south to north water diversion project construction needs a large number of products supporting the valve.
In addition, China is facing the arrival of the era of industrialization, petrochemical industry, power industry, metallurgy industry, chemical industry and urban construction, such as the use of large valve will enhance the demand for valve products. For example, the power industry, "Eleventh Five Year" period in coal-fired generating units in large and medium-sized projects required valve predict total: total demand valve 153000 tons, 3.06 million tons of annual demand, total demand valve 3.96 billion yuan, annual demand for the amount to 792 million yuan. In addition, China is becoming the world's largest factory, valve products processing production face greater space for development can be seen, as long as companies can seize opportunities, strengthen research and development capabilities, and continuously improve product technology content and product quality can in the fierce competition in the market occupy the initiative position.
In China's current valve market, in addition to the low pressure valve to achieve the level of international market acceptance, the high pressure valve still need to rely on imports. Under continued good macroeconomic situation, the valve industry, most of the enterprises production and sales targets are maintained rapid growth, but affected by the price war, industry sales revenue and profits compared with last year dropped significantly over the same period. As the world economy pick up, import and export of China valve products also increased, but because in the high-end technology with foreign manufacturers compared there is still a large gap, within a period of time in the future, technology products will become a bottleneck that restricts the development of our valve products.
From the product point of view, China's valve industry is now capable of producing more than a dozen categories of products, such as gate valve, cut-off valve, ball valve, butterfly valve, safety valve, check back valve, throttle valve, cock valve, relief valve, diaphragm valve, drain valve, emergency shut-off valve, the highest temperature reached 570 C, the lowest for - 196 DEG C, maximum pressure of 600 MPa, maximum through diameter to 5350 mm. In addition, according to the relevant departments of statistics, China's valve market turnover of up to 50 billion yuan per year, of which about 10000000000 yuan of market is occupied by foreign companies. Valves are oil, chemical, power station, long distance pipeline, shipbuilding, nuclear industry, a variety of low temperature engineering, aerospace and marine oil production and other sectors of the national economy and the indispensable fluid control equipment. After many years of development, China's number of valves in the world first, a variety of size of the valve business about more than 6000, of which more than 5 million yuan annual output value of 900.
At present, China's valve industry, there are still some problems, such as China's valve business mainly in low level, small scale, family workshop oriented enterprises. In the product, due to duplication of investment, the introduction of technology is not enough, the leading products of our valve business is still low quality mass products. At present our country enterprise production of various valves widespread leakage, internal leakage, the appearance of quality is not high, short life, the operation is not flexible and valve electric device and gas dynamic devices are not reliable shortcomings, some products is only in the early 80s of last century the international level, some key devices and high temperature and pressure of the valve is still dependent on imports.
