These arrows represent the flow paths the valve provides when it is in each position. Flow direction is indicated by the arrows in each box. The number of ‘position and flow boxes’ that make up a valve symbol indicate the number of valve positions. Every valve has at least two positions and each position has one or more flow paths, thus every valve symbol has at least two Flow Boxes to describe those paths. Check out our Interactive Pneumatic Circuit Symbols here. The Position and Flow Boxes indicate how the valve functions. The Actuators are the mechanisms which cause the valve to shift from one position to another. Most valve symbols have three parts (see Figure 2A below). Here is a brief breakdown of how to read a symbol. Symbols show the methods of actuation, the number of positions, the flow paths and the number of ports. Pneumatic circuit symbols representing these valves provide detailed information about the valve they represent. Directional air control valves are the building blocks of pneumatic control.
