What is the purpose of a pressure regulator? All pressure regulators reduce the high cylinder or system pressure to the proper lower working pressure What may result if a pressure regulator is not used on the type of has or pressure range for which it was designed? it can cause fire or an explosion Describe how a single stage regulator operates As the diaphragm is moved the small high pressure valve is opened allowing more gas to flow into the regulator.The gas pressure cancels ...
