Well from the Manufacturer website "Translated by Excite"

*Original Japanese FAQ http://www.nakano-iw.co.jp/qa/index.html
2-How much air enters?
A. Air keeps being filled to the tube until sending air when the wheel rotates, and becoming 3.0 atmospheric pressures that are the tire standard air pressures. Afterwards, when pressure in the tube becomes more than about 3.0 atmospheric pressures, the air sent from the hub is discharged from the relief valve.
So 3 atmosphere is about 44 psi.
And I don't think the valve is adjustable.
EDIT: Well the pressure valve might be change after all but
The relief pressure changes if six corner nut in the relief valve point is done in, the air short supply and entering too much do not occur, and never touch, please.
Well they say to never touch the hexnut. If you don't want to mess up with the pressure.
