Experiment 1: Operate the directional valve to observe how the cylinder moves up and down
Question 1: What does a hydraulic directional valve do?
Experiment 2: Observe where the flow goes when the valve is shut or cylinder at maximum stroke
Question 2: Where does the fluid go when the valve is shut?
Experiment 3: Change the load mass on the cylinder and observe what happens to the pressure
Question 3: Does the pump set the pressure?
Experiment 4: Change the load mass on the cylinder and observe what happens to the flow
Question 4: Does the speed change when the load pressure changes?
