Valves can be divided into industrial valves and civil valves, civil valves for the use of relatively low working conditions, mostly for daily water, heat, gas, etc., the valve is less demanding; and industrial valves for the use of relatively high working conditions or harsh, often require valves with high temperature, high pressure, corrosion and other characteristics. Industrial valves can be further divided into industrial automatic control valves (i.e. control valves) and industrial manual valves (i.e. process valves). Control valves and process valves in addition to the differences in the control mode, the biggest difference is the use of the scene and achieve different functions. Industrial manual valves can only realise the two-position on-site operation of open and close, and in the actual application scenario to maintain a state for a long time, seldom need to be operated, not easy to occur wear and tear, long service life. As one of the key terminal control equipment in the field of industrial process control, industrial automatic control valve integrates materials, machinery, fluid dynamics, fluid simulation, electronics, sensors, software, control and other technologies, and plays a role in the process control with other instrumentation, while controlling the flow rate accuracy, pressure, in order to achieve the ultimate goal of industrial automation control. Because of the industrial automatic control valve in the use of the process of control frequency is high, the existence of media on the valve body, spool larger erosion, so the industrial automatic control valve belongs to a kind of ‘consumables’.

China's control valves from the earliest in 1959 began production and manufacturing, a late start. At that time, the national designated production of control valves only five enterprises, mainly copying the products of the former Soviet Union, due to the low precision of machining, only to meet the general control requirements of the industrial production process at that time. From the 1980s, many factories have introduced foreign advanced technology, in order to improve the performance of the original product and further standardisation and serialisation on the basis of the development of side-mounted pneumatic control valves and lightweight control valves and other new products, China's control valves to achieve the development of a leap. Into the 21st century, the level of industrialisation makes control valves and automation control technology, automation control is increasingly becoming an important feature of the control valve, China's intelligent control valve industry has entered a period of rapid development.
