Power plant valve market analysis

Since the 1980s, China began to organize the backbone enterprises to introduce the foreign valve similar product design, technology and other advanced technology and processing equipment, has been the rapid increase of China's valve manufacturing technology and product quality. At present, the domestic production of valves backbone enterprises have been able to press the ISO international standards, DIN German Standards, AWWA American standards and other international standards design and manufacture of various valves, part of the manufacturers of the products has reached the international advanced level. Although the overall level of the valve industry in the past few years have been greatly improved, but the quality is not stable enough, such as run, run, drip, drain phenomenon in domestic valves often. In addition, hard sealing butterfly valve ball valve safety valve gate valve stainless steel valve hydraulic control valve safety valve sales burglar valve of valve supporting capacity also still some gap compared with developed countries.

The valve is a low-margin products, the market is very competitive. On the distribution of the valve market is mainly based on the construction of the project, the largest user of the valve is the petrochemical industry, power sector, metallurgy sector, chemical industry and urban construction departments. Petrochemical industry applications API standard gate valve, globe valve and check valve; electricity sector mainly uses the power station with high temperature pressure valve, globe valve, check valve and safety valve and a portion of the low pressure butterfly valve to the drain valve, gate valve; chemical industry mainly uses stainless steel gate valve, globe valve, check valve; metallurgical industry mainly uses low-voltage large-diameter butterfly valves, oxygen shut-off valve and the oxygen valve; urban construction sector mainly uses low-pressure valve, such as a city water pipe with large diameter valve, floor apartment building midline butterfly, urban heating metal sealing valve; pipeline mainly flat gate valve and ball valve; pharmaceutical industry mainly uses stainless steel ball valve; food industry mainly uses stainless steel ball valve. The large amount of valves used in the water treatment industry, mainly to the low-pressure valve products, such as butterfly valves, gate valves, check valves. It is understood that the valve enterprises of a certain size on the market more than 2,000, most are located in Jiangsu and Zhejiang and the Central Plains area. Requirements are relatively low technological content of products, therefore, more competitive.

On the one hand, China's valve products are facing good opportunities for development. With the oil development to the mainland of oil fields and offshore oil fields of the transfer, and the electric power industry by less than 300,000 kilowatts fire electricity to more than 300,000 kilowatts of thermal power and hydroelectric and nuclear power development, valve products should be based on the equipment application field changes corresponding change its performance and parameters. Urban systems generally use a large number of low pressure valves, and low iron gate that is used in the past to gradually shift to environment-friendly and energy-saving, environment-friendly plastic sheet valve, balance valve, metal sealed butterfly valve and midline sealing butterfly valve transition. Oil, gas projects to the pipeline in the direction of development, which in turn requires a lot of flat gate valve and ball valve. The other side of the energy development is energy conservation, from energy conservation to the development of the steam trap to the subcritical and supercritical parameters of the development.

Power plant construction to large-scale development, the need to use a large diameter and high pressure safety valve and pressure relief valve is also required to quickly open and close the valve. Sets the needs of the project, the valve is supplied by a single species to multi-species and multi-standard development. Valves required for a project, all provided by a valve manufacturer growing trend.
