The pressure must be always regulating while increasing. For a more precise regulation and higher sensibility, the use of a regulator with a pressure range as close as possible to the regulated pressure is recommended. Note Indifferent Assembly position Flow rate chart Pressure regulator Stainless steel line have been designed to withstand a 60 Bar maximum inlet pressure. Maximum regulated outlet pressure is 20 Bar.
