MEAD FLUID DYNAMICS
History
In 1939 MEAD FLUID DYNAMICS was established in Chicago, Illinois. For over 65 years fluid power and industrial automation has evolved into our focus and core business. Mead has long been a leader in the development of award winning pneumatic components. The pneumatic side offluid power is growing and is the backbone of American manufacturing. Mead Fluid Dynamics is positioned to be a part of that dramatic growth.

Section I: Valves Understanding Circuit Symbols
Directional air control valves are the building blocks of pneumatic control. Symbolsrepresenting these valves provide a wealth of information about the valve it represents. Symbols show the methods of actuation, the number of positions, the flow paths and the number of ports. Here is a brief breakdown of how to read a symbol:
2 Position, Lever Actuated, Spring Return Valve Every symbol has three parts (see figure to right). The Left and Right Actuators are the pieces which causethe valve to shift from one position to another. The Position and Flow Boxes indicate how the valve functions. Every valve has at least two positions and each position has one or more flow paths. When the Lever is not activated, the Spring Actuator (right side) Right Position & Flow Left Actuator Boxes Actuator is in control of the valve; the box next to the actuator is the current flow path.
