Actuators Complete Reference (Types, Attributes, Applications, and Suppliers)

Actuators are mechanical or electro-mechanical devices that allow for regulated and occasionally limited placement or movement. They can be powered by electricity, a manual operation, or a variety of fluids like air, hydraulic fluid, or other fluids.

Rotary and linear motion are the two fundamental motions.

In general, linear actuators are used for positioning applications and transform energy into straight-line motions.

They typically have a push and pull function. A revolving knob or handwheel can be used to manually operate a linear actuator when it is not powered. Energy is transformed into circular motion by a rotary actuator.

Controlling different valves, like ball valves or butterfly valves, is a typical use. Depending on the application, each actuator comes in a variety of designs and sizes and has a range of power settings.

The use of linear chain actuators is stiff chains used for pushing and pulling.
