Festo DRRD series twin-piston rotary actuators feature a rack and pinion principle with a very high bearing load capacity. The compact design of the DRRD series allows various configurations as a suitable solution for different applications.

Quarter turn actuators are suitable for automating butterfly valves, ball valves and air dampers. They are also suitable for water/wastewater, beverage, pharmaceutical and process automation.

Torque range: 1.6 Nm to 112 Nm
Double acting
Swivel angle: 180°
High bearing load capacity
High accuracy in end positions
Low backlash
IP65 design

Support rotational movement in your machinery with this size 20 pneumatic rotary actuator from Festo. As a rack and pinion type that can manage between 3 and 8 bar of operating pressure, it's ideal for use with medium-sized equipment. The unit's tempered steel drive shaft is strong and won't deform during operation. Flexible cushioning rings at both ends stop impact damage to prolong the life of your system. Improve feedback in your setup with an SME-series (121-5824) or SMT-series (250-2714) proximity sensor for improved control of the piston's location in sensitive applications.

• Wide operating temperature range between -10°C and +60°C for use in harsh environments
• Standard M5 pneumatic connection for easy installation in your existing gear
• IP65-rating means it's dust-tight and resistant to water jets, to suit industrial settings

• Manufacturing facilities
• Water treatment plants
• Agricultural machinery
• Automation systems

All double-acting pneumatic components work by receiving high-pressure air through a port at each end to push the internal piston from end to end. With rotary actuators, this mechanism produces a rotary motion instead of a backwards-and-forwards one.
