Valve is an important part of a large complete set of equipment, which is mainly used for cutting off, throttling, regulating pressure and changing flow direction of pipeline media (materials, water, steam, air and oil).

       The valve has many varieties and specifications, wide application and large consumption, which can be divided into industrial valve and civil valve. Industrial valves are mainly used to adjust the process parameters of medium flow, pressure, temperature and liquid level in the field of industrial automation process control.

       In the global industrial valve market demand, the oil and gas sector, including drilling, transportation and petrochemical, accounts for the highest proportion, followed by energy, electricity and chemical industry. Among the application fields of domestic industrial valves, the chemical industry, energy and power industry and oil and gas industry are also the most important markets for valve sales. In the next few years, with the rapid development of China's economy and the improvement of industrial automation, the transformation and upgrading of China's equipment manufacturing industry, as well as the continuous growth of national investment in oil and gas, petrochemical, environmental protection, electric power, metallurgy and other fields, the scale of China's industrial valve market will maintain a rapid growth.

       At present, China's key valve manufacturers have been able to design and manufacture various valves in accordance with international standards such as ISO international standards, DIN German standards, AWWA American standards and other international standards. The products of some manufacturers have reached the international advanced level, the overall level of the valve industry has been greatly improved, and some products have gone to overseas markets. However, compared with foreign products, the market competition of valve industry in China is fierce. At present, the scale of enterprises in the market is small, and medium and small enterprises account for more than 90%. Most of the enterprises are backward in technology and mainly concentrated in the low-end market. This leads to the lack of competitiveness of China's valve products in the international market and the lack of high-end product research and development.

       In recent two years, due to the impact of international trade friction, the international demand of valve products in China has declined, and the international trade has been challenged. According to the customs data, the export amount of China's valve industry fluctuated from 2017 to 2019, reaching US $16.624 billion in 2018, up 13.5% year-on-year; in 2019, the total export volume of China's valve industry fell to US $16.231 billion, down 0.02% year-on-year. In this context, Chinese valve enterprises should improve product technology and quality, increase high-end product research and development technology, catch up with international level as soon as possible, and improve international competitiveness.

       Relevant experts pointed out that qualified enterprises should speed up industrial upgrading and move towards medium and high-end valve products, such as oil, nuclear power and other national key development fields, and the market potential of domestic substitution of imported valves cannot be ignored. At present, China's economic situation and various policies continue to be favorable, which provides an extremely favorable development factor for China's valve industry. Although there is still a certain gap between China's valve industry and foreign valve industry, the key to our valve enterprises is to further improve the product quality and technical content. Only by consolidating the foundation and unremitting exploration and innovation, can China's valve brand be famous overseas and gain more market.
