Quarter-turn actuators DSR, metric
The Festo DSR quarter-turn actuators in metric sizes are pneumatic vane actuators with a fixed swing angle of 180°. The range covers sizes 10, 12, 16, 25, 32 and 40 mm, each available as the standard DSR and as the lightweight DSRL with flange mounting (suffix -FW). Both variants transmit torque through a central shaft and are suited to swivel and positioning tasks that require a defined 0°-180° switching motion.
