Introduction to Actuators

This interactive training unit is designed to introduce trainees to actuators in general, and pneumatic actuators, in particular. After completing this unit, trainees should be able to identify and describe three basic types of actuators and explain how actuators position control valves. They should also be able to describe the basic design and operation of single- and double-acting diaphragm actuators, single- and double-acting piston actuators, van actuators, and positioners. Finally, trainees should be able to describe some common actuator problems.
