Pneumatic air valve symbols.

Pneumatically controlled devices use pneumatic valves to control and direct the air and enable operations such as lifting moving pressing etc. These six basic valve symbols when combined with the basic actuator symbols comprise virtually all the directional valve symbols needed for air logic control. Symbols show the methods of actuation the number of positions the flow paths and the number of ports. Mechanical and air operated valves.

The symbols for these valve functions are shown in left graphic. Pneumatic symbols are used to describe the function of the various valves and other devices which are connected together to form circuits and sub circuits.

A close study of most air logic control circuits will reveal that there are only six basic valve functions commonly used.

Pneumatic circuit symbols representing these valves provide detailed information about the valve they represent. Here is a brief breakdown of how to read a symbol.
