Information

First, from the entire valve market, there are two main: 1, the domestic market, the domestic market is divided into new, expansion process project market, the old device maintenance, renovation project market. From the point of view of these two markets, the ordinary valve products seriously outstrip demand, followed by the pressure between enterprises, disorderly competition, counterfeit and shoddy ......, the market is very irregular, resulting in some valve manufacturers in the fierce competition, substantial losses year after year. From the point of view of the needs of these two markets, with the development and improvement of the market economy, especially the progress of the World Trade Organization (wto), its market changes more and more, enterprises are more and more deeply affected by the market, the user demand for market products are increasingly high, the demand for product development, production cycle is increasingly short. 2、Foreign market. Foreign markets have been very active in recent years, the competition is quite fierce. East and Southeast Asia's rapid growth in the import and export of valves, the European Community in North America and other developed countries between the market trade continues to develop, Germany, Italy, Japan, China and other countries and regions to expand exports, the United States, the United Kingdom, France and other countries imported high growth, forming the support of the international valve market prosperity, plus, due to the further internationalization of the world economy, multinational companies will continue to promote the international valve market Development, the regionalization of international trade is Bi become another major feature.

       Second, the domestic market, China's valve production of more than 2300 valve production more than three, can provide several categories of valve products, more than 3500 varieties, more than 40,000 specifications. (1) urban construction with valves: urban construction systems generally use low-pressure valves, is currently developing in the direction of environmentally friendly and energy-saving. Environmentally friendly rubber plate valves, balance valves and butterfly valves in the line, metal sealed butterfly valves are gradually replacing low-pressure iron gate valves. Domestic urban buildings need to use valves mostly balancing valves, soft seal gate valves, butterfly valves, etc. (2) urban heating valves: urban heat generation system, a large number of metal-sealed butterfly valves, horizontal balancing valves and direct burial ball valves, because these valves to solve the longitudinal and lateral hydraulic imbalance of the pipeline, to achieve energy saving, the purpose of heat generation balance. (3) environmental protection valves: domestic environmental protection systems, water supply systems mainly need to use midline butterfly valves, soft seal gate valves, ball valves, exhaust valves (for the exclusion of air in the pipeline). Sewage treatment system mainly requires a soft seal gate valve, butterfly valve. (4) city gas valves: city gas accounts for 22% of the entire natural market, the valve usage is large, and its type is also more. The main need for ball valves, plug valves, pressure reducing valves, safety valves. (5) long-distance pipeline valves: long-distance pipelines are mainly crude oil, finished products and natural pipelines. These pipelines require the majority of the valve is forged steel three-body full bore ball valve, sulfur-resistant flat gate valve, safety valve, check valve. (6) petrochemical devices with valves: a, oil refineries, oil refineries need valves are mostly pipeline valves, mainly gate valves, globe valves, check valves, safety valves, ball valves, butterfly valves, traps, of which, gate valves need to account for about 80% of the total number of valves, (valves account for 3% to 5% of the total investment in the device). b, chemical fiber devices, chemical fiber products are mainly polyester, acrylic, vinylon three categories. Its need for the valve of the ball valve, jacketed valve (jacketed ball valve, jacketed gate valve, jacketed globe valve). c, acrylic device. The device generally need to use api standard production of valves, mainly gate valves, globe valves, check valves, ball valves, traps, needle valves, plug valves, of which, gate valves account for about 75% of the total number of valves. d, synthetic ammonia device. As the original ammonia and purification methods are different, the process is different, the technical performance of the required valves are also different. At present, the domestic ammonia plant mainly requires gate valves, globe valves, check valves, traps, butterfly valves, ball valves, diaphragm valves, regulating valves, needle valves, safety valves, high-temperature low-temperature valves. Among them, globe valves account for 53.4% of the total data of the device with valves, gate valves account for 25.1%, traps account for 7.7%, safety valves account for 2.4%, regulating valves and low-temperature valves and other 11.4%. e. Ethylene plant, ethylene plant is the leading petrochemical plant, which requires a wide range of valves. Gate valves, globe valves, check valves, lift rod ball valves account for most of them, of which gate valves need to be at the top. The "Tenth Five-Year Plan", the country also needs to build 6 sets of ethylene devices with an annual output of 660,000 tons, the valve demand is considerable. In addition, large ethylene and high-pressure polyethylene devices also need to use ultra-high temperature, the lower temperature and ultra-high pressure valve series products. f, air separation device. "Air separation" that is, air separation, the device mainly requires a globe valve, safety valve, check valve, regulating valve, ball valve, butterfly valve, low-temperature valve. g, polypropylene device, polypropylene is easy to propylene as raw material, polymerization of polymer compounds, the device mainly requires a gate valve, globe valve, check valve, needle valve, ball valve, trap. (7) power station valves: China's power station construction is developing in the direction of large-scale, so the need for large-diameter and high-pressure safety valves, pressure reducing valves, globe valves, gate valves, butterfly valves, emergency shut-off valves and flow control valves, spherical seal instrumentation globe valves, (according to the national "Tenth Five-Year Plan", in addition to Inner Mongolia, Guizhou Province can also build 200,000 kilowatts (According to the national "Tenth Five-Year Plan", in addition to Inner Mongolia and Guizhou provinces can also build 200,000 kilowatts of units, other provinces and cities can only build 300,000 kilowatts of units). (8) metallurgical valves: metallurgical industry in the alumina behavior mainly need to use wear-resistant slurry valve (in the flow type shut-off valve), regulating traps. Steel industry mainly need to use metal sealed ball valves, butterfly valves and oxidation ball valves, shut-off flash and four-way reversing valve. (9) marine flat with the valve: With the development of offshore oilfield mining, the amount of its marine flat with the valve needs to gradually increase. Marine platform needs to use shut-off ball valves, check valves, multiway valves. (10) food and medicine valves: the industry mainly requires stainless steel ball valves, non-toxic all-plastic ball valves and butterfly valves. 3, foreign markets. With the entry into the WTO, China's valve market is facing competition from foreign valve manufacturers, the amount of imported valves from abroad will have a greater growth, at the same time, China's mid- and low-grade valve products, the production will have more space. (1) developed countries will buy valves from China into developing countries: developed countries need to buy valves from China, mainly api gate valves, globe valves, check valves, ball valves, butterfly valves, etc. (2) the Middle East, Iraq and other countries, oil fields, pipelines were destroyed from China's imports of oil systems and pipelines with valves: the Middle East, Iraq and other countries need to import from China's oil systems with valves, mainly gate valves, globe valves, check valves, long-distance pipelines are mainly flat valves and ball valves. (3) conventional import and export companies need to buy general general valves: this type of general valves from gate valves, globe valves, check valves, ball valves, butterfly valves mostly. At present, the domestic and foreign valve market competition is intense, especially in the domestic market, the competition between state-run enterprises and township enterprises and private individual enterprises, coupled with the relative weakening of their purchasing power, so that some valve companies face a crisis of survival, at the same time, some opportunities in foreign markets, but also lead to domestic enterprises to try to explore in order to survive. The opportunity to take advantage of the U.S. sanctions on the Middle East Iraq, Iran and the good export situation, China's higher quality, cheaper valve products, it is easy to enter the Middle East market, exports to developed countries. Therefore, all valve companies, should seize the opportunity to expand the market for the needs of the domestic and international valve market, increase exports for development.

       Third, the domestic valve should be developed new products Valve product development to focus on the national economic construction to develop. China's "Tenth Five-Year" economic construction is the focus of energy, agriculture, environmental protection industry and urban construction, that is, the future market for valve products mainly in the electric power, petrochemical, fertilizer, environmental protection and urban construction industries. And these industries, to be developed or are piloting but also need to improve the quality of valve products are: 1, high temperature, high pressure, forged pilot gate valve 2, forged steel high-pressure large-diameter globe valve 3, forged steel high-pressure large-diameter check valve 4, metal sealed, oil-sealed avdco valve 5, fully welded full diameter pipeline ball valve 6, lifting rod ball valve 7, large-diameter emergency cut-off butterfly valve 8, fully welded direct burial ball valve 9, High-performance butterfly valve (ans1b16.1046 level, life of more than 500,000 times 10, pilot-operated safety valve 11, api6a flat gate valve 12, api6achokt2s valve 13, control flash (regulating valve) 14, regulating trap 15, oil products with propped soft seal plug valve 16, deep-sea oilfield with (3000m below the sea floor) gate valve, ball valve 17, high-pressure Large-diameter top-loading ball valve 18, alumina high-pressure melt out with slurry valve 19, natural gas regulating device In addition, the valve test device also needs to further improve the development. At present, although China's valve industry manufacturers are gradually increasing scientific research and development efforts, but the product technology lags behind, making the competition ineffective, the production of valve varieties can only meet about 70% of the market demand. The shortage of low-pressure large-diameter valves and the contradiction between production and demand in the varieties and materials of high and medium pressure valves, as well as the above-mentioned new products to be developed, all need our valve companies old research, development and expansion. Competition in the market, always the best and the worst. Accelerate the adjustment of product structure, technology updates, the development of new products, the creation of each brand ...... is the foundation of the enterprise's own survival, development, accounting for the market at home and abroad.
