Description
2 psig / 0.14 bar Service Regulators
The Types RJ622E and RJ652E regulators are
designed for high pressure (pounds per square inch)
vapor service. These regulators have high capacity
internal relief valves.
The Type RJ622E or RJ652E standard outlet
pressure setting is 2 psig / 0.14 bar. The regulator is
painted PALM GREEN with a WHITE CAP. It is an
intermediate stage regulator that reduces 10 psig /
0.69 bar first stage pressure to 2 psig / 0.14 bar. They
are used on 2 psig / 0.14 bar pressure systems. The
Types RJ622E and RJ652E are not suitable for first
stage service.
Second Stage Low Pressure Regulators
The Types RJ622, RJ642 and RJ652 regulators
provide low pressure (inches of water column) delivery
pressures. They are normally set at 11 in. w.c. /
27 mbar pressure. They have high capacity internal
relief valve construction. The regulators are normally
painted PALM GREEN. The units differ in construction
and capacity rating.

Installation
▲
WARNING
All vents should be kept open to
permit free flow of air in and out of the
regulator. Protect vent openings against
the entrance of rain, snow, ice formation,
paint, mud, insects, water from an
irrigation system or any other foreign
material that could plug the vent or vent
line or accumulate in the vent line.
LP-Gas may discharge to the
atmosphere through the vent. An
obstructed vent which limits air or
gas flow can cause abnormally high
pressure that could result in personal
injury or property damage. Failure to use
a vent line on Indoor Installations can
cause a hazardous accumulation of gas
which could result in personal injury or
property damage.
