ACE95 Series valves respond to slight decreases in
internal tank pressure by opening and increasing the
flow rate of inert gas into the tank. When the tank's
liquid level has been lowered to the desired point and
the vapor pressure set point is re-established, the valve
closes.
Installation and Startup
Personal injury, equipment damage, or
leakage due to escaping accumulated gas
or bursting of pressure-containing parts
may result if this gas blanketing system
is over pressured or installed where
service conditions could exceed the
limits given in the Specifications section
and on the appropriate nameplate, or

where conditions exceed any ratings of
the adjacent piping or piping connec-
tions.
To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices (as required by Title 49, Part 192,
of the U.S. Code of Federal Regulations,
by the National Fuel Gas Code Title 54 of
the National Fire Codes of the National
Fire Protection Agency, or by other
applicable codes) to prevent service
conditions from exceeding those limits.
Additionally, physical damage to the tank
blanketing system could result in per-
sonal injury and property damage due to
escaping accumulated gas. To avoid such
injury and damage, install the tank
blanketing valve in a safe location.
