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. Important note for automatic drain For inlet pressure from 0 to 10 bar use the reduced automatic drain (SR version) For inlet pressure from 10 to 16 bar use the STD automatic drain (S version)
