Overview
The control valve is a control component in the fluid conveying system, which has the functions of cut-off, regulation, diversion, prevention of backflow, voltage stabilization, diversion or overflow and pressure relief. Industrial control valves are mainly used in process control in industrial equipment and belong to the instrument, instrumentation and automation industries.
1. The control valve is similar to the arm of a robot in the process of realizing industrial automation, and is the final control element for changing process parameters such as medium flow, pressure, temperature, and liquid level. Because it is used as the terminal actuator in the industrial automation process control system, the control valve, also known as the “actuator”, is one of the core devices of intelligent manufacturing.
2. The control valve is the key basic component of industrial automation. Its technical development level directly reflects the country’s basic equipment manufacturing capacity and industrial modernization level. It is a necessary condition for the basic industry and its downstream application industries to realize intelligence, networking and automation. . Control valves are generally composed of actuators and valves, which can be classified according to function, stroke characteristics, power used by the equipped actuator, pressure range, and temperature range.
Industrial chain
The upstream of the control valve industry is mainly steel, electrical products, various castings, forgings, fasteners and other industrial raw materials. There are a large number of upstream enterprises, sufficient competition and sufficient supply, which provides a good basic condition for the production of control valve enterprises; Wide range of downstream applications, including petroleum, petrochemical, chemical, paper, environmental protection, energy, mining, metallurgy, medicine and other industries.
From the perspective of production cost distribution:
Raw materials such as steel, electrical products and castings account for more than 80%, and manufacturing costs account for about 5%.
The largest downstream application field of control valves in China is the chemical industry, accounting for more than 45%, followed by the oil and gas and power industries, accounting for more than 15%.
With the upgrading of industrial control technology in recent years, the application of control valves in papermaking, environmental protection, food, pharmaceuticals and other fields is also developing faster and faster.
Industry size
China’s industrial development continues to improve, and the level of industrial automation continues to improve. In 2021, China’s industrial added value will reach 37.26 trillion yuan, with a growth rate of 19.1%. As the terminal control element of the industrial control system, the application of the industrial control valve in the industrial control system effectively improves the stability, accuracy and automation of the control system. According to the data of Shanghai Instrument Industry Association: in 2021, the number of industrial automation control system enterprises in China will further increase to 1,868, with revenue of 368.54 billion yuan, a year-on-year increase of 30.2%. In recent years, the output of industrial control valves in China has increased year by year, from 9.02 million sets in 2015 to about 17.5 million sets in 2021, with a compound annual growth rate of 6.6%. China has become one of the world’s largest producers of industrial control valves.
The demand for industrial control valves in downstream industries such as chemical and oil and gas continues to increase, mainly including four aspects: new investment projects, technical transformation of existing projects, replacement of spare parts, and inspection and maintenance services. In recent years, the country has adjusted the industrial structure and transformed the economy. The growth mode and vigorous promotion of energy conservation and emission reduction measures have an obvious stimulating effect on the project investment and technological transformation needs of the downstream industries. In addition, the normal update and replacement of equipment and inspection and maintenance services have also brought stable demand for the development of the industry. In 2021, the scale of China’s industrial control valve market will be about 39.26 billion yuan, a year-on-year increase of over 18%. The industry has high gross profit margin and strong profitability.
Enterprise pattern
my country’s industrial control valve market competition can be divided into three levels,
In the low-end market, domestic brands have been able to fully meet the market demand, the competition is fierce, and the homogeneity is serious;
In the mid-end market, domestic enterprises with relatively high technical level represented by Tianjin Tanggu Water-seal Valve Co.,Ltd occupy part of the market share;
In the high-end market: the penetration rate of domestic brands is relatively low, which is basically occupied by foreign first-line brands and professional brands.
At present, all domestic mainstream control valve manufacturers have obtained ISO9001 quality system certification and special equipment (pressure pipeline) TSG manufacturing license, and some manufacturers have passed API and CE certification, and can comply with ANSI, API, BS, JIS and other standards Design and manufacture products.
My country’s huge control valve market space has attracted many foreign brands to enter the domestic market. Due to strong financial strength, large technical investment and rich experience, foreign brands are in the leading position in the control valve market, especially the high-end control valve market.
At present, there are a large number of domestic control valve manufacturers, generally small in scale and low in industrial concentration, and there is a clear gap with foreign competitors. With the breakthrough in domestic industrial control valve technology, the trend of import substitution of high-end products is irreversible. .
Development trend
My country’s industrial control valve has the following three development trends:
1. Product reliability and adjustment accuracy will be improved
2. The localization rate will increase, and import substitution will be accelerated, and the industrial concentration will increase
3. Industry technology tends to be standardized, modularized, intelligent, integrated and networked
