7.9 Quad-Valve™ Exhaust Assembly
The Quad-Valve™ exhaust became standard on the
Kirby Morgan 37 helmet as of March 2005. This is a
superior exhaust system that ties together the regula-
tor exhaust and the helmet exhaust into one unit with
exceptionally low exhalation resistance.
The Quad-Valve™ is nearly identical in design to
the previously standard Tri-Valve™. The difference
between the two units is that the Quad-Valve™ uses
the quad exhaust cover to connect the exhaust body to
the exhaust main body. All other parts are identical.
If you have an older KM37 helmet you are strongly
encouraged to upgrade your helmet to the Quad-
Valve™ design with the Quad Valve cover.
7.9.1 Quad-Valve™ Assembly Removal
Tools Required: Screwdriver
Small cutting pliers
NOTE: It is necessary to first remove the regulator
and Quad Valve exhaust assembly from the helmet
to separate the Quad-Valve™ Assembly from the
regulator.

1) Removal of the Quad-Valve™ Assembly is started
by cutting the tie wrap that holds the assembly to
the regulator. After removing the tie wrap, stretch
the exhaust main body over and off of the regulator
exhaust flange.
To remove the Quad-Valve™ exhaust from the
helmet you must first cut the tie-wrap that secures
the exhaust main body to the regulator.
