Use in general service
Verify the actuator’s nameplate to ensure correct model number, torque output, operating speed,
voltage and enclosure type before installation or use.
It is important to verify that the torque output of the actuator is appropriate for the torque
requirements of the valve and that the duty cycle of the actuator is appropriate for the intended
application.
