Getting Pneumatic or Electric Actuators?

Electric actuators and pneumatic actuators do similar jobs, but they should not be used interchangeably. The two different actuators have their own set of characteristics, which make them good for certain jobs and bad for others. If you focus your attention on four aspects of your jobs, it will help to ensure you get the correct products.

The first thing to consider is the performance characteristics of what you need and what the two devices can provide. What sort of duty cycle do you need? How about stalling and speed control? A pneumatic actuator has programmable speeds, is shock proof, does not overheat, and has a 100% duty cycle. On the other hand, an electric actuator has fixed speeds, must be modified to work in extreme condition/environments, can easily overheat, and has a standard cycle of 25% (can be upgraded to a higher percentage).

Next, you must consider spring return (fail-safe options). If you want spring returns for added safety, you will need to go with a pneumatic system. Spring returns are available for electronic versions, but they are expensive and harder to find.

Lastly, you must consider your power source and temperature range. As mentioned earlier, both actuators cannot be used interchangeably. If you need help making a decision about actuators, reach out to professional companies in the field.

The same principles apply for pneumatic counters and pneumatic valves. Choose wisely.
