Reversing: Rotates clockwise to open a valve and counterclockwise to close a valve. Asahi/America Actuation Electric Actuator Design-Spur Gear Stator Motor Pinion Gear Capacitor Gearbox Main Output Gear Asahi/America Actuation Duty Cycle Duty Cycle is the ratio between actuator cycle time and the “cool off” time required based on 100% to avoid thermal cut out. Example: 25% Duty Cycle means that the unit can be cycled 25% of the time. If the actuator is cycled for 1 minute continuously, Necessary cool off time is 3 minutes.
