Valve is a product with low profit margins, and the market competition is fierce. The distribution of the valve market is mainly based on the construction of the project. The largest users of the valve are the petrochemical industry, the electric power sector, the metallurgical sector, the chemical industry and the urban construction department. The petrochemical industry mainly uses the gate valve, cut-off valve and check valve of API standard; the electric power department mainly adopts the high temperature gate valve, cut-off valve, check valve and safety valve and a part of the low pressure butterfly valve and gate valve of the power station, and the chemical industry mainly adopts stainless steel gate valve, cut-off valve and check valve, and the metallurgical industry mainly adopts low level. Big caliber butterfly valve, oxygen cut-off valve and oxygen ball valve; urban construction department mainly adopt low pressure valve, such as city water pipe mainly adopt large diameter gate valve, building construction mainly adopt middle line butterfly valve, city heating mainly adopt metal seal butterfly valve; oil pipeline mainly use flat gate valve and ball valve; pharmaceutical industry owner Stainless steel ball valves shall be adopted, and stainless steel ball valves shall be used in the food industry. Valves are widely used in water treatment industry, mainly for low pressure valve products, such as butterfly valves, gate valves and check valves. It is understood that at present, there are more than 2000 valve enterprises in the market, most of which are distributed in Jiangsu, Zhejiang and Central Plains. Because of the relatively low requirement of the technical content of products, the competition is more intense.

Since 80s, our country began to organize the advanced technology and processing equipment, such as the design and processing of the same kind of foreign products imported from the backbone enterprises, so that the manufacturing technology and product quality of the valve in our country have been rapidly improved, and it has basically reached the level of foreign 80s. At present, domestic valve production backbone enterprises have been able to design and manufacture various valves according to international standards such as ISO international standard, DIN German standard, AWWA American Standard, and some of the products of some manufacturers have reached the international advanced level. Although the overall level of the valve industry in the past year has been greatly improved, but the quality is not stable, such as running, running, dropping, leakage phenomenon in domestic valves often appear. In addition, there is still a certain gap between China's valve supporting capacity and developed countries.

On the one hand, valve products in China are facing good opportunities for development. With the transfer of oil development to the mainland and offshore oil fields, as well as the development of power industry from 300 thousand kilowatts of thermal power to more than 300 thousand kilowatts of thermal power and hydropower and nuclear power, the valve products should also change their performance and parameters according to the changes in the field of equipment application. The urban construction system generally uses a large number of low pressure valves, and to environmental protection and energy saving type, that is, the low pressure iron gate valve used in the past is gradually turned to environmental protection type of rubber plate valve, balance valve, metal seal butterfly valve and middle line seal butterfly valve transition. Oil and gas transmission projects are developing towards pipelines, which requires a large number of flat gate valves and ball valves. The other aspect of energy development is energy saving. Therefore, from the point of view of energy conservation, we should develop steam traps and develop them to sub critical and supercritical ones.

The construction of the power station is developing to a large scale, so large and high pressure safety valves and pressure relief valves are required. The demand for complete sets of engineering valves is supplied from a single variety to multiple varieties and specifications. There is a growing trend for all valves required by a project to be supplied by a valve manufacturer

But on the other hand, we have to take seriously many problems in the valve market. As China's valve market has basically formed a state-owned, collective, joint ventures, shares and private ownership co-exist. In the fierce market competition, the demand for steady development, enterprises are concerned about the following issues: efforts to reduce production costs, focus on improving the performance and efficiency of products; develop the grade of high and new products or production of single small batch of non standard products; through the international quality certification of the valve products; valve products should be environmentally friendly, energy saving In the direction of development. However, it is inevitable that some illegal manufacturers, who aim to make profits and do harm to others' interests, are disrupting the normal market development of valve products.

In general, the price of China's valve market is relatively stable, though it has a slight rise or fall every year, but the scope is very small. Looking from the North China valve market, many enterprises have been found to be profit shoddy and seriously disrupted the valve market. The main problems in the valve market are as follows: 1. Some operators buy Valves without factory names, print famous manufacturers' famous brands and qualified certificates, and cause serious harm to the reputation of qualified valve enterprises. Two, renovation valve, part of the operator through the re sale of waste valves after second sales, to the quality of the project to bring serious security risks.

Through the analysis of the valve market, it is not difficult to find that the market of China's valve products has a good prospect, but it is necessary to eliminate malignant competition by standardizing market order and strict management, and calling for the conscience of the same industry and the quality supervision of the government.
