At present in China valve industry about 10% of the market occupied by foreign enterprises, China General Machinery Industry Association stakeholders valves branch that, in order to change this situation, improve the quality of the valve is the key.
The valve has a sizable proportion of mechanical products. According to foreign industrial countries, the valve output is the sum of the compressor, fan and pump the three, accounting for the machinery industry output value of 5%. At the same time, as an important part of major technical equipment, especially in electric power, petrochemical, metallurgy, city water supply and drainage system, the valve is a key role, but the amount is very large. At present, China's valve business is about more than 6000, of which more than 5000000 yuan annual output value of 900. Domestic listed companies 3 valve, namely, nuclear technology, Seong shares, Guangdong pearl. Last year, nuclear science and technology of main business income of 235000000 yuan, Seong shares the main business income of 146000000 yuan, Guangdong Pearl of the main business income of 150000000 yuan. These enterprises, regardless of their size, or quality of products, are currently unable to compete with the big foreign enterprises.
Analysis of the industry, resulting in the cause of passive valve market in China are mainly two aspects: one is the domestic products and imported products than there are gaps, the quality to be improved; the two is some users localization is not strong, even artificially set the threshold, so that domestic enterprises and foreign enterprises in the bidding is difficult to bid. Concerned expert thinks, at present the production of various valves enterprises in our country widespread leakage, internal leakage, appearance quality is not high, short life, the operation is not flexible and pneumatic valve actuators and devices are not reliable shortcomings, some of the products is equivalent to the last century eighty's early international level. Therefore, the development of the valve industry, urgent need to develop new products with high technology content.
