Accept the continuous gas signal, the output linear displacement (plus / after the gas conversion device can also receive continuous electrical signal), and some coupled with the rocker, the output angular displacement.
There are positive and negative functions.
The speed is large, but the speed increases as the load increases.
The output force is related to the operating pressure.
High reliability, but the gas source can not be maintained after the interruption (plus the bit valve can be maintained).
Inconvenient to achieve segment control and program control.
Maintenance and repair is simple, good adaptability to the environment.
Output power is large.
With explosion-proof function.
