Asahi/America Actuation Unidirectional: Rotates in one direction only and stops every 90 degrees until signaled to move again. Reversing: Rotates clockwise to open a valve and counterclockwise to close a valve.

Asahi/America Actuation 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.

Asahi/America Actuator Types Double Acting (Air to Air): Requires air to open and air to close. No fail position if air supply is lost. Spring Return (Air to Spring): Requires air to open only, once air is exhausted springs close the valve. Fail position open or close if air supply is lost.
