Description
pneumatic,electric,hydraulic actuators and their working principle;applications and differences of all three types;The purpose of a control valve actuator is to provide the motive force to operate a valve mechanism.

Can't really understand some of what is being said. And doesn't allow for subtitles/captions
The first lecture on the type of Actuator was repeated for the Pneumatic Actuator and the lectures were not descriptive enough.
Terrible course. He just shows a bunch of poorly made sketches and talks about theories. Won't recommend it.
very bad
Poor explanations. Never even explains the purpose of his videos. Uses the same diagram for the first two videos so far.
