XL-160/XL-180 Component Locations
The Liquid Valve - Liquid product is added or withdrawn from the con-
tainer through the connection controlled by this valve. It has the CGA
fitting that is required for liquid connections.. The valve is opened for fill
or liquid withdrawl after connecting a transfer hose with compatible fittings
to the LIQUID line connection.
The Pressure Gauge - Thepressure gauge dsplays teh internal container
pressure in pounds per-square-inch, bar or in kiloPascals.
The VENT Valve - This valve controls a line into the head space of the
container. It is used during thet fill process. the VENT valve is opened to
vent the head space area while liquid is entering the inner container
during a pressure transfer fill through the LIQUID valve.
The Full View Contents Gauge - The container contents gauge is a float
type liquid level sensor that indicates container liquid content through a
magnetic coupling to a yellow indicator band. This gauge is an indication
of approximate container contents only and should not be used for filling.
Relief Devices - These cylinders have inner container relief valves set at
22 psig (1.5 bar/152kPa) and inner container bursting disc that will rupture
at 176 psig (12 bar/1213)
