Types R622E and R652E, 2-PSI Regulators are Underwriters Laboratories (UL) listed regulators designed for 2-PSI LP-Gas systems. They are installed downstream from a first-stage regulator to reduce an inlet pressure of 10 psig / 0,69 bar to a nominal 2 psig / 0,14 bar outlet pressure. The 2-PSI Regulators are designed for domestic applications that supply 2 psig / 0,14 bar LP-Gas to a line regulator located inside the building. These units have white closing caps for easy identification.
