Valve is an indispensable fluid control equipment in petroleum, chemical, power station, long-distance pipeline, shipbuilding, nuclear industry, various low-temperature engineering, aerospace and marine oil extraction. After years of development, the number of valve enterprises in China ranks first in the world. There are more than 6000 valve enterprises of various sizes, of which 900 have annual output value of more than 5 million yuan.
In Chinas current valve market, in addition to low-pressure valves to reach the international market acceptable level, high-pressure valves still need to rely on imports. In the macroeconomic situation, most of the enterprises in the valve industry have maintained rapid growth in production and sales indicators. However, affected by the price war, the industrys sales revenue and profits decreased significantly compared with the same period last year. With the recovery of the world economy, the import and export of valve products in China has also increased. However, there is still a big gap in high-end technology compared with foreign manufacturers. In the future, product technology will become a bottleneck restricting the development of valve products in China.
From the product situation, Chinas valve industry has been able to produce more than ten categories of products, such as gate valve, globe valve, check valve, ball valve, safety valve, pressure reducing valve, needle valve, regulating valve, diaphragm valve, butterfly valve, solenoid valve, drain valve, plunger valve, plug valve, forged steel valve, needle valve, instrument valve, liquid level meter, flowmeter, exhaust valve, flame arrester, knife gate valve, slurry valve, copper valve, balance valve, Stainless steel valve, fluorine lined rubber lined valve, pipe clamp valve, American Standard valve, power station valve, breathing valve, hydraulic control valve, vacuum valve, discharge valve, pneumatic angle seat valve, heat preservation valve, filter, bottom valve, balance valve, blowdown valve, etc. the maximum service temperature is 570 ℃, the minimum is - 196 ℃, the maximum pressure is 600MPa, and the maximum diameter is 5350mm. In addition, according to the statistics of relevant departments, the annual turnover of valve market in China is as high as 50 billion yuan, of which more than 10 billion yuan market is occupied by foreign valve enterprises.
