1.Domestic valve market characteristics

From the entire valve market point of view, there are two:

(1)The domestic market, the domestic market was divided into new, expanded market agenda item, the old equipment maintenance, renovation project market. From two market, ordinary valves punish generations greater than demand, and secondly, between enterprises race to pressure Yang, disorderly competition, fake ... the market is very irregular, resulting in some valve manufacturer in the fierce competition in substantial losses year after year. From two market demand, with the market economy development and improvement, especially progressive WTO (WTO), its changes in the market is growing, companies affected by the market more and more, users on the market increasingly high demand for the product, product development, production and demand cycles are getting shorter.

(2)Foreign markets. Very active in foreign markets in recent years, the competition is fierce. East and Southeast Asia valves rapid export growth, the North American market between the EU and other developed countries trade continued to develop, Germany, Italy, Japan, China and other countries and regions, export expansion, the United States, Britain, France and other countries imported high-speed growth, the formation of the international valve market prosperity anchor Moreover, the further internationalization of the world economy, multinational companies will continue to promote international valve market development, international trade regionalization is completed to become another great feature.

2.The domestic market. Approximately three of valve production over 2300, to provide valve products have several categories, more than 3500 varieties, more than 40,000 specifications.

(1) City building valves: Urban systems generally use low pressure valves, are currently being environmentally friendly and energy-saving direction. Environmentally friendly plastic sheet valve, balance valve and butterfly valve, metal sealed butterfly valve is gradually replacing low-iron gate. Domestic mostly urban architecture required valve balance valve, soft seal gate valve, butterfly valve and so on.

(2) Urban heating valves: Cities generation thermal system, which requires large amounts of metal sealing butterfly valve, ball valve horizontal balancing valve and buried, because this type of valve solutions pipeline longitudinal, lateral hydraulic imbalance problems and achieve energy saving, generation of heat balance purposes.

(3) Environmental protection valves: domestic environmental protection system, water supply system is mainly required butterfly valve, soft seal to the valve, ball valve, exhaust valve (used to exclude the air pipe). Sewage treatment system is mainly required soft seal gate valve, butterfly valve.

(4) City gas valves: city gas market, accounting for 22% of all natural, valves large amount of its type, too. Main need ball valves, plug valves, pressure reducing valve, safety valve.

(5) Long pipeline valves: long-distance pipelines are mainly crude oil, refined and natural pipeline did. The majority of such pipelines to be the amount of the valve is forged three-body full bore ball valve, anti-sulfur flat gate valve, safety valve, check valve.

(6) Petrochemical plant valves:

a. Oil refining equipment, oil refining equipment required valves are mostly pipeline valves, mainly for gate valves, globe valves, check valves, safety valves, ball valves, butterfly valves, steam traps, in which the total number of gate valves need to account for about 80% (valve device of the total investment accounted for 3% to 5%).

b. Chemical equipment, chemical products mainly include polyester, acrylic, polyvinyl alcohol three categories. Which required the ball valves, jacketed valve (jacketed ball valves, jacketed valve, jacketed cut-off valve).

c. Acrylonitrile devices. The device is generally required API standard production valves , mainly for gate valves, globe valves, check valves , ball valves , steam traps, needle valves, plug valves, which , gate valve of the total accounted for about 75% . 

d. Ammonia plant . Since the original ammonia and purification methods, the process , the required technical performance valves are also different. At present , the domestic ammonia plant mainly required gate valves, globe valves, check valves , steam traps, butterfly valves, ball valves , diaphragm valves , control valves , needle valves , safety valves, high temperature valves. Among them, the shutoff valve apparatus representing 53.4% ​​of the total data valve , gate valve accounted for 25.1% , 7.7% trap , safety valve (2.4%) , regulating valves and cryogenic valves and other share from 11.4%. 

e. Ethylene , ethylene plant is the leading petrochemical device which required a wide range of valves . Gate valve, globe valve, check valve , lift rod ball in the majority, which topped gate needs . "Fifteen " plan , the country needs to build an annual output of 660,000 tons of ethylene unit 6 sets , substantial demand for its valves . In addition, large-scale ethylene and high-pressure polyethylene plant needs to use ultra-high temperature , low temperature and high pressure valves more products.

f. Air separation plant. "ASU" means air separation, the device is mainly required valves, safety valves, check valves, control valves, ball valves, butterfly valves, cryogenic valves.

g. Polypropylene plant, polypropylene Yi is propylene as raw materials, polymerization of polymers, the device is mainly required gate valves, globe valves, check valves, needle valves, ball valves, steam traps.

(7) Power station valves: My positive large-scale power plant construction direction, so the need to use large diameter and high pressure safety valve, pressure reducing valve, globe valve, gate valve, butterfly valve, emergency shut-off valve and flow control valves, spherical sealing instrumentation valves, (according to the national "Tenth Five" plan, in addition to Inner Mongolia, Guizhou provinces also build 200,000 kilowatts or more units, other provinces and cities can only build 300,000 kilowatts or more units).

(8) metallurgical valves: metallurgical industry mainly required wear behavior of alumina slurry valve (shut-off valve in the flow), adjust the trap. Steel industry is mainly required metal sealing ball valves, butterfly valves and oxidation ball valve, globe flash and reversing valve.

(9) Sea level combination valve: With the development of offshore oil exploration, the ocean level the amount of hair required valve is gradually increasing. Offshore platforms required shutdown valve, check valve, multi-way valve.

(10) food and medicine with the valve: This industry is mainly required stainless steel ball valves, non-toxic plastic ball valves and butterfly valves.

3. The foreign market. With entering WTO, China's valve market is facing foreign competition valve manufacturers, valve imported from abroad will have a larger amount of growth, while China's medium and low valve products produced there will be more space.

(1) From developed countries into developing our purchase valves: the developed countries need to buy from our valves, mainly for API gate valve, globe valve, check valve, ball valve, butterfly valve and so on.

(2) Middle East, Iraq and other countries, oilfields, pipelines destroyed China's imports from the oil system and pipeline valves: Middle East, Iraq and other countries to be imported from the country's oil system used mainly for gate valves, globe valves, check valves, long-pipeline mainly flat valves and ball valves.

(3) Regular import and export companies need to buy general purpose valves: these universal valve from the valve, globe valve, check valve, ball valve, butterfly majority.

At present, domestic valve market competition is very intense, especially in the domestic market, state-owned enterprises and township enterprises and private individuals, competition among enterprises, coupled with its relatively weak purchasing power, so that some enterprises are facing a crisis of survival valves, while the foreign markets some opportunities, but also led to domestic enterprises to open up in order to survive. By the United States in the Middle East Iraq, Iran sanctions promising opportunities and export situation, China's higher quality, cheaper valve products, it is easy to break into the Middle East market, exports to the developed countries. Therefore, all the valves enterprises should seize the opportunity, the demand for domestic valve market, expand markets, increase exports, in order to develop.
