Valve oil, shipbuilding, nuclear industry, a variety of low-temperature projects, chemical, power station, long distance pipeline, aerospace and marine oil and other economic sectors indispensable fluid control equipment.
After years of development, China’s valve business volume ranks first in the world. There are about 6,000 up-scale enterprises totally, among them, there are 900 which annual output value over 500 million.
In china current valve market, in addition to low-pressure valve have achieve a level acceptable for the international market, the high-pressure valves still need to rely on imports. Thanks to continuous good macroeconomic situation, most production and sales targets of valve industry are maintaining rapid growth, howover industry sales and profits dropped significantly over last year due to the price war. As the world economy revovery slowly, import and export of our valve products also increased gradually. Because of the high-end technology, compared with foreign manufacturers,there are still a wide gap in the next period of time. Product technology will be a bottleneck restriction of our valve products development.
In some opinion, China’s valve industry is now capable of producing more than a dozen categories of products, such as gate valve, globe valve, check valve, ball valve, butterfly valves, safety valve, relief valve, piston valves, plug valves, knife gate valve, slurry valve, filter, foot valve, control valves, diaphragm valves, balance valve, solenoid valves, forged steel valves, needle valves, liquid level, flow meter, breather valve, exhaust valve, flame arrester, instrument valves, copper valve, stainless steel valves, lined rubber lined valves, Pinch Valve, power station valve, hydraulic control valve, vacuum valve, discharge valve, pneumatic angle seat valves,the U.S. standard valve, insulation valve, discharge valve, the maximum temperature reached 570 ℃, a minimum of -196 ℃, the maximum pressure of 600MPa, the maximum diameter to 5350 mm. In addition, according to the relevant departments of Statistics, China’s valve market turnover each year up to 500 billion yuan, of which more than 100 billion market take up by the foreign valve enterprises.
At present, China’s valve industry, there are still some problems, such as valve company in China are mainly low-level, small-scale, family-owned enterprises. About products, due to duplication of investment, technology transfer is not enough, the valve leading enterprise products in China is still low quality mass products. China’s production is currently widely impressed with following shortcomes, leakage of various valves, internal leakage, the poor appearance, short life, the operation is not flexible and electric valve actuators and pneumatic devices are not reliable, some of the products technology is only about 80s of the last century early international level, a number of high temperature and pressure and the critical need for the valve device is still rely on imports. Besides, A big gap between china and foreign is still existed in the industrial structure of China’s valve industry, valve industry, the industrial chain, and industry degree of specialization.
The reason of poor quality valve: the rapid market expansion, the original state-owned enterprises have been close, stop, merge, transform, although a number of township enterprises developed rapidly, due to the low starting point of township enterprises, the technical power is very weak, poorly equipped , imitation products are mostly production, especially for the low pressure valve in water industry.
But the problem does not affect the future prospects of China’s valve industry wide. This is mainly due to the support of national policies and strong market demand for valve products, especially in several centuries, “natural gas”, “West to East”, “South” and started the project requires a large number of valve products supporting. In addition, China is faced with the arrival of the industrial age, the petrochemical industry, power industry, metallurgy industry, chemical industry and urban construction will push the use of large valve products. For example, the power industry, coal units in large and medium-sized valves required for the project started was forecast totally: 153,000 tons valve, 30,600 tons in the average annual ; valve amount of the total demand of 39.6 billion with an annual demand amounted to 792 million yuan. In addition, China is becoming the world’s largest factory, manufacture for valve products with even greater space for development.
Thus, as long as companies can seize opportunities, strengthen research and development capabilities, and continuously improving product technology and product quality, can have a bright future in the fierce market competition.
