  • Duty Cycle
  • Nema Ratings
  • Switches
  • Flow Control Loop
slide12

Asahi/AmericaActuation

Unidirectional:

Rotates in one direction only and stops every 90 degrees

until signaled to move again.

Reversing:

Rotates clockwiseto open a valve and counterclockwiseto

close a valve.

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.

Pneumatic Actuator Terminology

  • Designs
  • Double Acting (Air to Air)
  • Single Acting (Spring Return)
  • Switches
slide23

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.
