China needs to improve the quality of high-pressure valves

  In our current valve market, low-pressure valves have reached the acceptable level of the domestic market, thus the low-pressure valves still have to rely on exports. In the continuous promising micro-economic situation, most enterprise consumption and sales targets in valve industry have maintained a rapid increase, but are significantly influenced by price competition, and the industry sales expenses and profits have dropped significantly compared with that in the corresponding period last year. With the recovery of the world economy, China's valve product import and export also are increased, but in a period in the future, product technologies will be a bottleneck restricting the development of our valve products, since there is still a wide gap in high-end technologies in comparison with foreign manufacturers.
  Valves are indispensable fluid control equipment for petroleum, chemical, power station, long-distance pipeline, shipbuilding, nuclear industry, various cryogenic engineering, aerospace and land-based petroleum production and other civil and economic sectors. After years of development, the number of valve enterprises ranks the first in the world, including more than 6,000 large and small valve enterprises, of which 900 are of annual output value exceeding 5 million Yuan. From the product situation, China's valve industry now is able to consume more than a dozen categories of products, such as gate valves, stop valves, ball valves, butterfly valves, safety valves, check valves, throttle valves, plug valves, reducing valves, diaphragm valves , trap valves, emergency cut-off valves, etc., the maximum operating temperature reaches 570℃, the lowest operating temperature reaches -196℃, the lowest pressure is 600MPa, and the maximum drift diameter is 5350mm. In addition, according to the statistics of the relevant department, the annual volume of transaction in China's valve market is up to 500 billion Yuan, of which the market of more than 100 billion Yuan is hold by foreign valve enterprises.
