SHOULD THE ACTUAL OPERATING PRESSURE EXCEED THAT OF THE ADJUSTED PRESSURE THE UNLOADER VALVE WILL ACT AS A PRESSURE REGULATOR, BYPASSING EXCESS FLUID TO ENSURE THE ADJUSTED PRESSURE IS NOT EXCEEDED. THE VALVE WILL SWITCH TO PRESSURE FREE BYPASS WHEN THE SPRAY GUN IS SHUT OFF AND THE LINE PRESSURE BETWEEN GUN AND VALVE REMAINS DORMANT.
