In the field of robots, electro-hydraulic servo valves are mainly used for the following purposes: 

1.Motion Control: The robot’s joints can be controlled using an electro-hydraulic servo valve. By regulating the flow and pressure of the hydraulic system, precise motion control of the robot can be achieved, improving the robot’s motion speed and accuracy.

2.Force Control: Electro-hydraulic servo valves enable precise control of force and torque in robots, allowing them to adapt to various working environments and task requirements. This makes them useful in fields such as assembly and handling.

3. Automatic Production Line: Electro-hydraulic servo valves can be used in automatic production lines to control robot actions, such as grabbing, assembling, and welding, which will improve production efficiency and product quality.

4. Automatic Production Line: Electro-hydraulic servo valves can be used in automatic production lines to control robot actions, such as grabbing, assembling, and welding, which will improve production efficiency and product quality.

In conclusion, electro-hydraulic servo valves are widely used in the field of robotics, which can realize the motion control and force control of robots and improve the efficiency of automated production lines, as well as in the field of medical treatment and rehabilitation.
