Key Features
Double-Acting Rotary Vane Design
The actuator uses a double-acting rotary vane mechanism to convert compressed air pressure into controlled rotational movement in both directions. A suitable pneumatic directional control circuit is required.
5 Nm Theoretical Torque at 6 bar
Festo specifies a theoretical output torque of 5 Nm at 6 bar. Actual available torque depends on operating pressure, load conditions, friction and system configuration.
Elastic End-Position Cushioning
Elastic cushioning rings or pads at both ends help absorb motion at the travel limits. The specified cushioning angle is 1.8°, supporting appropriate mechanical motion control within the actuator's operating limits.
1.5–8 bar Pneumatic Operation
The actuator operates with compressed air at pressures from 1.5 to 8 bar and features M5 pneumatic connections, allowing integration into appropriately designed industrial air-control systems.
Compact Industrial Construction
The DSR-25-180-P combines a die-cast zinc housing, nickel-plated steel drive shaft and NBR seals. Through-hole mounting and unrestricted mounting orientation provide flexibility for suitable equipment installations.
Applications
- Industrial pneumatic rotary motion systems
- Automated assembly equipment positioning

Frequently Asked Questions
What is the Festo DSR-25-180-P?
It is a Festo DSR series double-acting pneumatic rotary vane actuator with an adjustable swivel range of 0° to 180°, M5 pneumatic connections and a theoretical torque of 5 Nm at 6 bar.
What is the manufacturer part number?
The official Festo article number for DSR-25-180-P is 11911.
What is the maximum rotation angle?
The actuator has a maximum swivel angle of 180°. The travel can be adjusted within the specified 0° to 180° range.
Is DSR-25-180-P single-acting or double-acting?
It is a double-acting rotary actuator. Compressed air is used to drive rotational movement in both directions.
What is its operating pressure range?
Festo specifies an operating pressure of 1.5 to 8 bar, equivalent to 0.15 to 0.8 MPa.
How much torque does the actuator produce?
Its theoretical torque is 5 Nm at 6 bar. This is a reference operating value, not a guarantee of the same output torque at every pressure or load condition.
Does the actuator include end-position cushioning?
Yes. The P version has elastic cushioning rings or pads at both ends, with a specified cushioning angle of 1.8°.
What pneumatic port size is required?
The DSR-25-180-P uses M5 pneumatic connections. Check the fitting thread, tubing dimensions and air-supply arrangement before installation.
What is the maximum swivel frequency?
The manufacturer specifies a maximum swivel frequency of 3 Hz at an operating pressure of 6 bar. The permissible application frequency also depends on the load and mechanical installation.
Does the DSR-25-180-P include an integrated position sensor?
No. The manufacturer specifies this model without integrated position sensing. Any external monitoring solution must be selected and validated separately.
Can the Festo DRVS series replace the DSR-25-180-P?
Festo identifies the DRVS series as a modern alternative to the DSR rotary actuator family. However, direct interchangeability is not guaranteed. Verify shaft dimensions, mounting, torque, pneumatic connections, swivel angle and load requirements.
What should be checked before ordering?
Confirm the exact model DSR-25-180-P, Festo part number 11911, size 25, double-acting rotary vane design, adjustable 0° to 180° rotation, 5 Nm theoretical torque at 6 bar, 1.5 to 8 bar operating pressure, M5 pneumatic connections, spigot shaft, through-hole mounting and the installation dimensions of the existing equipment.
