Before we begin if you do not understand how valve’s are represented diagrammatically or what is the difference between a 3/2 valve and a 5/2 valve, I strongly recommend that you watch this video to understand it.

Experiment 1

A double acting cylinder is to be extended on pressing a push button A “Forward Button” and Retract on pressing a push button B (“Reverse Push Button”) . Speed is to be controlled in both the directions.

Schematic :

1

Press Button A is pressed for Forward movement of the double acting cylinder and
Press Button B is pressed for Reverse movement.

Speed in both the directions is controlled with the help of the ‘One way flow control valve’ for each respective directions.

2

Note the orientation of the One Way Flow Control Valve (should look something like a Martini Glass )

3

Double Click on the One Way Flow Control Valve to set the opening level for speed control.

Experiment 2

A double acting cylinder is to be extended on pressing a push button A “Forward Button” and Retract on pressing a push button B (“Reverse Push Button”) . Speed is to be controlled in forward direction, return should be rapid.

Schematic :

Experiment 3

A double acting cylinder is to be extended on pressing a push button A “Forward Button” and Retract on pressing a push button B (“Reverse Push Button”) . Speed is to be controlled during retraction, forward should be rapid.

Schematic:

The logic for experiment 2 and 3 is similar to the first experiment, except the speed control is only in one direction either forward or reverse .
Since speed control is only in one direction, a singleĀ One Way Flow Control Valve is used for that particular direction and a Quick Exhaust Valve is used for the opposite actuation.
