Tips: What are the advantages of pneumatic valve actuators?
- It has positive and negative functions.
- The moving speed is large, but the speed will become slower when the load increases.
- The output force is related to the operating pressure.
- High reliability, but the valve cannot be maintained after the gas source is interrupted (it can be maintained after adding a retaining valve).
- It is inconvenient to realize segment control and program control.
- Simple maintenance and good adaptability to the environment.
- Large output power.
