Pneumatic Air Valve Symbols

Pneumatic circuit symbols representing these valves provide detailed information about the valve they represent.

Pneumatic air valve symbols.

Symbols show the methods of actuation the number of positions the flow paths and the number of ports. 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. Available in svg png jpg dxf dwg formats.

Pneumatic valves symbols for use in electrical pneumatic and hydraulic schematic diagrams.

Mechanical and air operated valves. Here is a brief breakdown of how to read a symbol. These six basic valve symbols when combined with the basic actuator symbols comprise virtually all the directional valve symbols needed for air logic control. Pneumatic symbols only when the design fails does it draw attention to itself.

A close study of most air logic control circuits will reveal that there are only six basic valve functions commonly used. Directional air control valves are the building blocks of pneumatic control.
