1 Pneumatic Schematics Using Graphic Symbols to Illustrate Basic Circuit Designs

2 3/2 Solenoid Valve Regulator Pneumatic Components Single Acting Pull Type Cylinder and Speed Valve

3 Pneumatic Component Symbols 3/2 Solenoid Valve Regulator Single Acting Pull Type Cylinder and Speed Valve

4 The Symbols Can Be Arranged to Illustrate Complete Circuits Double Acting Cylinder HPA Storage Bottle Regulator 4/2 Valve HP Gage LP Gage

5 5/2 Solenoid Valve Note: The center port with the brass One Touch Fitting is the supply or pressure port. 5/2 Solenoid Valve Symbol Solenoid Valve Body

6 5/3 Solenoid Valve Used on Double Acting Cylinders The Solenoid Operates Like a Linear Pneumatic Motor 1.) Wire coil (red) is energized 2.) The electromagnetic field, draws the iron armature (blue) into the solenoid 3.) The valve spool (green) moves with the iron armature Solenoid Valve Spool Springs return valve spool to rest position AB PEBEA

7 5/2 Solenoid Valve Used on Double Acting Cylinders 5 Ports, 2 Positions The 2 Dark Blocks Represent the Two Possible Valve Positions Solenoid At Rest Position Solenoid Energized Position B Pressurized : A Exhausted (rest) A Pressurized : B Exhausted (energized)

8 5/2 Solenoid Valve Used on Double Acting Cylinders 5 Ports, 2 Positions Return Spring Symbol Indicates the At Rest Position Actuator Symbol with a Diagonal Line Indicates Solenoid Operation

9 5/2 Solenoid Valve Used on Double Acting Cylinders 5 Ports, 2 Positions Letters A and B Indicate the Output Port Connections for the Pneumatic Actuators (Cylinders) The Arrow Symbols Indicate the Direction of Gas Flow Through the Valve EA and EB are Exhaust Ports. P is the Gas Supply Port

10 Hopefully the Hieroglyphics of Pneumatics are More Understandable Double Acting Cylinder HPA Storage Bottle Regulator 4/2 Valve HP Gage LP Gage

11 Watch the 2 Position Valve and Double Acting Cylinder

12 5/2 Valve 5 Ports 2 Positions 5/3 Valve 5 Ports 3 Positions Can You Explain the Difference?

13 Pictorial Drawing of a 5/3 Valve and Double Acting Cylinder PEBEA A B Note: At Rest, Ports A and B are Exhausted P is Closed

14 Mini Pneumatic Circuits Pressurized Storage Bottle Regulator 3/2 Valves Pneumatic Cylinders with Speed Valves

15 Pneumatic Schematics The Best Way to Learn Them, Is to Draw Them….Try It.
