Quarter Turn Actuator for Industrial Valve Control

The Festo DSR-1 is a quarter turn actuator designed for precise rotary motion in pneumatic and automation systems. It suits maintenance engineers and system integrators who need reliable 180-degree actuation for process valves or damper drives in industrial environments.

Verify Mounting Pattern

Confirm that the valve or driven device accepts the quarter turn interface and that the available compressed air supply meets the actuator’s operating pressure range. Ensure the control signal voltage matches your PLC or relay output and that the 1/4 inch port thread aligns with existing tubing or fittings.

Compact Unit That Frees Panel Space

The actuator mounts directly to the valve body, eliminating external linkage brackets and reducing the overall footprint inside the cabinet. Its integrated design removes the need for separate positioner hardware, while the red finish aids quick visual identification during routine inspections.

Questions about this item

What comes in the box with the DSR-1 1/4"-180-P 33127 actuator and what must I purchase separately?

The box contains one quarter-turn actuator in red finish. No mounting hardware, tubing or control valves are included; source those separately to suit your installation.

How do I decide between the available versions of the DSR-1 actuator?

The product is offered as a single configuration — 1/4" port, 180° rotation, model 33127 — so there are no alternative capacities or versions to choose from.

What does the 180° rotation spec mean when the actuator is installed in a pneumatic system?

It indicates the output shaft travels a full half-turn from end stop to end stop, delivering quarter-turn valve actuation within that angular range.
