Comparing Hydraulics and Pneumatics
Learners examine the differences and similarities between hydraulic and pneumatic systems.
Simple Pneumatic Circuits
Learners examine the operation of five pneumatic animated circuits that use directional control valves, pilot lines, check valves, needle valves, and cylinders.
Hydraulic Schematic Symbol Flashcards
By John Rosz
This interactive object is designed to help learners memorize schematic symbols used in hydraulic diagrams. Learners quiz themselves using electronic flashcards.
Hydraulic Mechanical Force
This animated lesson shows how to calculate the amount of force generated by hydraulic cylinders.
In this animated activity, learners examine the three main segments of a hydraulic system: power supply, control, and output. A brief quiz completes the learning object.
By Terry Bartelt, Stephen Schneider
In this animated object, learners examine the internal structure of an unloading valve. This learning object includes a video clip demonstrating the use of an unloading valve in a metal stamping application.
Designing a Cylinder Dwell Circuit
This animated lesson shows how a ladder circuit uses timer-on delays to cause an extrusion machine to operate.
Learners view an animation of a counterbalance valve in operation and examine the valve’s internal structure.
In this animated object, learners examine how aeration develops in a hydraulic pump. A brief quiz completes the activity.
Comparing Electronic and Hydraulic Components
Learners read about the similarities of electronic and hydraulic components and then match the schematic symbols in a drag-and-drop exercise.
Hydraulic Cylinder Speed
In this interactive and animated object, learners examine why the piston of a hydraulic cylinder extends slower than it retracts. A brief quiz completes the activity.
Pressure Relief Valves
In this animated object, learners examine the operation of a hydraulic relief valve and its internal components. A brief quiz completes the activity.
In this animated object, learners examine how various types of positive and non-positive displacement hydraulic pumps work.

Hydraulic System Pressure
In this animated activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.
Pressure-Reducing Valve Application
In this animated activity, a drill-and-clamp machine is used to show an application of a pressure-reducing valve. Recommendations on how to properly make pressure adjustments are also provided.
Photoelectric Reciprocation Circuits
This animated lesson shows how a photoelectric sensor, connected to a ladder circuit, causes the cylinder of a hydraulic circuit to extend and retract.
Flow Control Valves
In this colorful and animated activity, learners study the operation of a needle valve and the operation of the needle valve with a check valve. A brief quiz completes the activity.
Hydraulic Brake Valves
The operation of a hydraulic brake valve, including the internal components, is presented using animations.
Types of Pneumatic Compressors
Learners examine the operation of positive and non-positive displacement compressors used in pneumatic systems.
