As a control component in a fluid delivery system, the valve has functions such as cut-off, regulation, diversion, backflow prevention, pressure regulation, diversion, or pressure relief. Valves used in fluid control systems, ranging from the simplest shut-off valves to various valves used in highly sophisticated automatic control systems, are quite diverse in variety and size. The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media. It is used in various industries and in various working conditions.

Although the valve is a component, it is an indispensable part of major technical equipment, especially in the power, petrochemical, metallurgy, fertilizer, environmental protection, urban water supply and drainage systems, the valve is playing a role in fluid control The key role. For example, in a power plant, valves can control the operation of boilers and steam turbines. In petroleum and chemical production, valves also control the normal operation of all production equipment and processes. The same is true in other sectors. In spite of this, compared with other products, valves are often overlooked. For example: When installing machinery and equipment, people tend to focus on the main machinery and equipment but ignore the valves. This will reduce the overall production efficiency or stop production, or cause a variety of other accidents. Therefore, we also need to be more careful and cautious in the selection, installation, and use of the valve to ensure the good execution of each step of the production process.

After years of development, the number of valve companies in China has ranked first in the world. There are more than 6,000 valve companies of all sizes, including about 900 valve companies with an annual output value of over 5 million yuan. From the product point of view, China's valve industry has now been able to produce more than 10 categories of products, such as gate valves, globe valves, ball valves, butterfly valves, safety valves, check valves, throttle valves, plug valves, pressure reducing valves, diaphragm valves, Traps, emergency shut-off valves, etc., the maximum operating temperature of 570 °C, the minimum operating temperature of -196 °C, the maximum pressure of 600 MPa, the maximum diameter of 5350 mm.

Although China's domestic valve manufacturing industry has achieved certain results in recent years, it still has a certain gap compared with the international advanced level. Many high-parameter, high-temperature, high-pressure, high-pound critical valves have always depended on imports. In order to promote the localization of valves, following the State Council’s “Several Opinions on Accelerating the Revitalization of the Equipment Manufacturing Industry”, the relevant departments of the State have successively made a series of major deployments in accordance with the requirements of the country’s major equipment for localization, and are led by the National Development and Reform Commission. , China Machinery Industry Federation and China General Machinery Industry Association, deployed and formulated the valve localization program for major equipment in related fields, and coordinated with related departments several times. Nowadays, localization of valves has formed a consensus in the domestic valve industry. After 20 years, consensus has been reached. In particular, the joint efforts of scientific research, design, manufacture, and users in recent years and joint research have been effective.

West-to-East Gas Transmission Project, South-to-North Water Diversion Project, Three Gorges Water Control Project, Million-kilowatt nuclear power unit, million-ton ethylene renovation project, supercritical and ultra-supercritical thermal power unit, oil and gas pipeline transportation, coal chemical industry, large-scale ship, and municipal wastewater In areas such as major engineering and equipment projects and nuclear power, petrochemical, metallurgy, and power stations, in addition to a small number of high-parameter safety valves and regulating valves that need to be imported, localization of valves has been realized, which has changed the key equipment of major equipment and is subject to foreign regulations for a long time. situation. And strive to achieve as much as possible in the short term major projects and key valves to achieve localization, or part of the realization of localization, so that China's valve manufacturing industry in the forefront of the world.

China's valve industry more than 300,000 industrial army, in the past 2011, firmly seize the trend of the valve industry to pick up, take full advantage of the large domestic investment in construction and energy and other projects, the large demand for valve products, pick up, based on a good valve industry In the real economy, we actively engaged in the manufacture of valve products and the development of the market. Through the joint efforts of the entire industry, we achieved a favorable situation in the production and sales of the valve industry.

According to relevant department statistics, China's valve industry achieved sales and sales revenues exceeding 190 billion in 2011, and valve output reached more than 5 million tons, an increase of 15% to 18% over the same period of last year. Its valve output has already become one of the world's leading manufacturing nations. Production and sales performance hit another record high. Among them, among the major economic indicators, the total profit realized is about 6% of the annual sales revenue. At the same time, the valve products have been greatly improved along with the localization level, and there has also been a historic shift. The import of valve valves has decreased and the export has increased. The output of valve production is about 20-30 billion yuan, among which the imported valves are about 10 billion. Yuan around.

The good development of the valve industry and the support of relevant national policies have promoted the better development of each enterprise engaged in valve production and sales. However, although the "cake" in the valve market in China is large, the market competition is also very fierce. To stand out in this kind of competition, in addition to the perfect equipment, advanced technology, good reputation and perfect service is also an essential part. As a non-regional industry limited liability company integrating valve R&D, production, sales and service, China Dongjin Valve has provided us with the best proof of our own actions.

Founded in 1985, China Dongjin Valve Co., Ltd. is located at the birthplace of China's private economy, Wenzhou's coastal town - "China Valve City" seaside industrial park, covers an area of ​​38,688 square meters.
