ADVUL compact cylinder
The Festo ADVUL compact cylinder is a single-acting spring-return variant from the Festo short-stroke range. Bore diameters span 12 to 100 mm with strokes starting from 5 mm. In contrast to the double-acting ADVU/AEVU types, the ADVUL uses an integrated return spring to retract the piston rod when the air supply is exhausted. All variants carry a magnetic piston (suffix -P-A) for use with Festo proximity sensors.

How to choose ADVUL compact cylinder
What matters when choosing: properties, comparison and typical applications.
Technical features
Selection by bore and stroke
| Bore (mm) | Typical strokes (mm) | Mode of action |
|---|---|---|
| 12 | 5-40 | Single-acting, spring return |
| 16-25 | 5-80 | Single-acting, spring return |
| 32-63 | 5-80 | Single-acting, spring return |
| 80-100 | 5-80 | Single-acting, spring return |
The ADVUL is the preferred choice for applications without a second pressure port. The spring force determines the return force and must be accounted for during system design. All common bore-stroke combinations are available from stock.
Typical applications
Typical applications: Clamping and holding fixtures where force is applied by air pressure and released by the spring, locking mechanisms with a defined rest position, and simple infeed or ejection tasks in assembly and test equipment.
