Basic Pneumatic
Circuits
These common pneumatic circuits can be used alone or
as building blocks in larger pneumatics systems.
Basic Pneumatic Circuits
1. Air Preparation
2. Double-Acting Cylinder
3. Continuous Cycling
4. Two-Hand Control
Table 1. Basic pneumatic circuits.
Common Air Preparation Circuit Components
1. Manual Shut-Off Relief Valve, VLV01
2. Filter, FIL01
3. Regulator with Gauge, REG01 and GUA01
4. Pneumatic Distribution Block, not shown
5. Soft-Start/Dump Valve, VLV02
6. Lubricator, if needed, LUB01

neumatics have been used in automated machines for well
over 100 years, with pneumatic technology developing and
evolving for over 1,000 years in some form or another; for
example, as boat sails.
There have been many innovations over the years and the
basic pneumatic components such as valves, solenoids, cylinders,
hoses, and fittings are well developed and mature. These devices
can be combined in many ways to provide simple and reliable
machine control.
This article examines pneumatic design best practices and
then presents four basic pneumatic circuits (Table 1) commonly
used in machine automation. While there are many variations,
these pneumatic circuits combine basic pneumatic components
to create functional and reliable pneumatic circuits.
Pneumatic Design Best Practices
Before discussing these four basic pneumatic circuits, it's best to
review best practices for pneumatic design. While there is a long list
of potential pneumatic problems - such as low or varying air pressure,
improper use of flow controls, air cylinders banging at power
up, and slow or inconsistent cylinder speed - following good
pneumatic design practices can address these and other issues.
