It's there for a reason. Most likely because it would be bad if air would travel in the wrong direction because it would cause a vacuum leak or something. I am probably wrong with what it does on that motor, but I am not wrong in saying its there for a reason. Please do not remove stuff off your motor without knowing why its there and what it does and what it affects.
And yes it's a one way check valve.

Looks like that check valve sits between the intake and the ADD switching valves. Probably functions similar to the check valve in the brake booster line. That one is there to only allow engine vacuum to pull air out of the device (increasing the internal vacuum) and not allow that vacuum to drop when the engine vacuum drops, like when you mash the throttle down. Without that valve, you might find your front axle disconnecting and dropping you back into 2WD just when you hit the gas to get out of the mud pit.
