Flow Solutions

Flow Pattern
RA Series double acting actuators produce guaranteed minimum torque outputs up to 16,500 In-Lbs (1865 Nm). The spring return units produce spring start torques up to 10,200 In-Lbs (1159 Nm). The actuator full travel can be adjusted between 80° to 100° operation. The image to the right shows the different flow solutions the RA series is capable of.
