Electro-hydraulic Proportional Valve

Electro-hydraulic proportional valves are valves that can accurately control the size of the flow through electrical signals, converting electrical signals into hydraulic signals to achieve precise control of fluids. This type of valve has the advantages of fast response speed, high control accuracy, compact structure, and easy installation and maintenance. Electro-hydraulic proportional valves are usually used in industrial applications that require fine control, such as automotive manufacturing, aerospace, precision machining, and other fields.

Servo Valve

Servo valves are another type of valve that can accurately control fluid flow, but unlike electro-hydraulic proportional valves, it directly controls the position of the valve core through electrical signals, thereby achieving precise control of fluid flow direction and speed. Servo valves have the advantages of fast response speed, high control accuracy, and good dynamic performance, and are suitable for applications that require high-precision control, such as CNC machine tools, robots, precision instruments, and so on.

Application

The application scenarios of electro-hydraulic proportional valves and servo valves are different. Electro-hydraulic proportional valves are suitable for situations that require continuous and fine adjustment of fluid flow, while servo valves are suitable for applications that require rapid and accurate control of fluid flow direction and speed.

Summary

Electro-hydraulic proportional valves and servo valves are indispensable execution elements in modern industrial automation, playing a vital role in improving production efficiency and ensuring product quality. With the development of technology, the application scope of these two types of valves will be further expanded, and they will show their unique value in more fields in the future.
