Analysis of control valve industry development and market structure in 2018

1、 Development course of control valve industry in China

China's control valve industry started late, but developed rapidly. In the 1960s, China began to develop single seat valve, double seat valve and other products, mainly imitating the products of the former Soviet Union. Due to the backward level of machinery industry and low machining accuracy, it can only meet the general control requirements of industrial production process at that time.

In the 1970s, with the expansion of industrial production scale and the improvement of industrial process control requirements, domestic control valve products can no longer meet the control requirements of high pressure difference, low temperature, high temperature and strong corrosion in production process control. For this reason, some large petrochemical enterprises have introduced some overseas advanced control valves, such as sleeve valve with balancing spool, eccentric rotary valve, etc., while importing equipment, which has become the development direction of domestic control valve manufacturers.

Since the 1980s, with the implementation of China's reform and opening-up policy and the rapid development of petrochemical, metallurgical, electric power and other industries, some control valve manufacturers began to introduce the technology and products of foreign famous control valve manufacturers, which significantly improved the variety and quality of China's control valve products. At the same time, the Ministry of machinery industry organized key enterprises in the industry to develop a series of fine and small control valves, which initially improved the product series of control valves in China.

In the 1990s, with the improvement of domestic industrialization level, China's control valve enterprises also made great progress after introducing and digesting foreign advanced technology. A number of private control valve enterprises came into being, especially some joint venture control valve enterprises began to develop and produce their own products, which promoted the substantial improvement of China's control valve industry level, It shortens the gap with foreign countries.

Since the 21st century, with the continuous progress of science and technology, the original control valve products have been unable to meet the market demand. Some intelligent control valve products with automatic control technology are gradually welcomed by the market. Since then, China's intelligent control valve industry has entered a period of rapid development. During this period, a number of control valve manufacturers emerged in the market. Among the state-owned enterprises, Wuzhong instrument and Chuanyi Co., Ltd. were the industry leaders, while private enterprises such as Zheneng Automatic and Dagao valve also became market participants with high-quality products and services.
