Each valve switching position isrepresented by a square.
The number of squares corresponds
to the number of switching positions.
Lines indicate the flow path,arrows show the direction of flow.
Shut-off positions are identified in theboxes by lines drawn at right angles.
The connections (inlet andoutlet ports) are shown by lineson the outside of the box.
