Instrument valve market, the main problems

Meter valves are products with low profit margins and the market is highly competitive. The major users of the valve are the petrochemical industry, the power sector, the metallurgy sector, the chemical industry and the urban construction sector. At present, there are more than 2,000 valve companies with a certain scale on the market, most of which are located in the areas of Jiangsu, Zhejiang, and Central China.

With the shift from oil development to oil fields in the interior and offshore oil fields, and the development of thermal power and hydropower and nuclear power from 300,000 kilowatts to less than 300,000 kilowatts in the power industry, valve products should also change their performance in response to changes in equipment applications. parameter. Urban construction systems generally use a large number of low-pressure valves, and are developing towards environmental protection and energy-saving, that is, the low-pressure iron gate valves used in the past have gradually shifted to environmental-friendly rubber sheet valves, balancing valves, metal sealing butterfly valves and midline sealing butterfly valves. Oil and gas transmission projects are developing in the direction of pipelines. From the perspective of energy conservation, steam traps have to be developed and developed to subcritical and supercritical high parameters.

The construction of the power station has grown to large scale. Therefore, large-diameter and high-pressure safety valves and pressure reducing valves are required, and valves must be opened and closed quickly. The needs of complete sets of projects, valve supply from a single species to more varieties and more specifications. The need for a valve for an engineering project is increasingly provided by a valve manufacturer.

In general, the price of China's valve market is relatively stable. Although there is a slight increase and decrease every year, the range is very small. From the North China valve market, it has been discovered that many companies have shoddy for profit, seriously disrupting the valve market. The main problems in the valve market are:

Some operators purchase valves with no factory name, print well-known manufacturers' nameplates and certificates, and cause serious damage to the reputation of qualified valve companies. Refurbishment of the valve, some of the operators through the second sale of the repainted waste valves, bring serious safety risks to the quality of the project.
