It is true that the development of control valves is closely related to the industrial process. True, in ancient times people came up with the idea of ​​regulating. People try to regulate the flow of water in rivers or streams by using large rocks or tree trunks to block the flow of water or change the direction of the flow of water at the time. And there are even some simple original valves used for crop irrigation in the Egyptian and Greek civilization. Later, the Romans developed a complex water system for irrigating crops and used plug and plunger valves to prevent backflow. Then the Industrial Revolution has proposed the development to a new stage. James Watt invented the first speed controller setting. People at that time tended to pay more attention to flow regulation.

A pump governor, like the fist control valve, was invented by William Fisher in 1880. This is a kind of self-control valve with a heavy hammer. When the pressure increases, the valve opening decreases under the effect of the heavy hammer to achieve a stable pressure. During the 1920s, ball valves are most popular, along with one-way or two-way V-notch globe valves. By the 1940s, diaphragm valves and butterfly valves were introduced to control flow. mass. Then the valve positioner was developed. During the 1950s, three-way valves and cage valves were made to meet high requirements. In the 1970s, cage valves, especially eccentric plug valves, were popular in many industrial process fields. And since 1980, a variety of fine and small control valves, control valve actuators are born with the aim of reforming the weight, height and circulation of valves. Entering the 21st century, the fieldbus control valve was applied. And it is sure that the requirement of control valves will be higher in the future.

Control valves and development of industrial processes developed simultaneously. To improve the quality of control, it is certain that exact requirements are required on the control system and on the composition of all constituent parts. As the whole society keeps a fast pace, it is necessary to understand the advanced technologies and put them into practice. It is obvious to develop all the time. Otherwise, the entire industry, even the entire society, would not progress.
