Schematic Symbols for Directional Valves
A directional valve is a valve that directs the flow of air in one with or another. It
doesn't throttle or meter the airflow, and it doesn't change the pressure of the air. It
just changes the direction of the airflow in some way. The ANSI symbol for
directional valves are
the most complicated of all the fluid power symbols, but some
of the most important, so let us start with directional valves, see how the symbol
system works.
A typical directional valve symbol is made up of three parts:
The actuators are the devices or methods that cause the valve to shift from one
position to another.

position to another.
The valve
