HRE-458 Air-filled Remote Enclosure
An optional breather vent valve is enclosed in the List 2 shipping kit. This assembly is used to replace the pressure
relief valve if the List 2 is not locally pressurized. The assembly allows the enclosure to breathe and keeps the
internal atmosphere free of harmful contaminants. The five metal valves are shown in
.
Two O-rings are required between the brass fitting and adapter of the pressure relief valve, the
brass fitting and breather vent valve, the brass fitting and breather adapter of the air stem
valve, and the body housing and limiting nut of the pressure cutoff valve. Without the presence
of both O-rings in each case, a proper seal cannot be achieved.
