Features and functions
Self-locking: Output speeds up to 90 rpm (50 Hz), 108 rpm (60 Hz)
NOT self-locking: Output speeds from 125 rpm (50 Hz), 150 rpm (60 Hz)
Multi-turn actuators are self-locking if the valve position cannot be changed from standstill while torque
acts upon the output drive.
Self-locking
Yes, multi-turn actuators are self-locking, if the valve position cannot be changed from standstill while
torque acts upon the output drive.
