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
personal injury and property damage
due to escaping accumulated gas.
To avoid such injury and damage,
install the tank blanketing valve in a
safe location.
This Type ACE95jr tank blanketing valve was
assembled and preset to the customer specified
pressure and setpoint. The control pressure range of
the valve is stamped on the nameplate fastened to the
upper actuator case. The gas blanketing setpoint is the
only adjustable feature on this unit.
1.
Get a qualified personnel when installing, operating,
and maintaining valves. Before installing, inspect
the valve and tubing for any shipment damage or
foreign material that may have collected. Make
certain the body interior is clean and the pipelines
are free of foreign material. Apply pipe compound
only to the male pipe threads with a screwed
body or use suitable line gaskets and good bolting
practices with a flanged body.
2. Inspect the nameplate on the upper actuator
case. It displays the model number, serial number,
a blanketing gas supply pressure range, the
maximum inlet pressure, set pressure and C
V
value. These must agree with the system that you
are blanketing. The serial number will be needed
in any communication with your local Sales Office.
3. Clean the gas blanketing supply lines of all dirt
and foreign material before connecting them to the
Type ACE95jr tank blanketing valve.
4. The valve must be mounted so the actuator
case is horizontal, as shown in Figure 3. The
valve should be mounted above the tank. Three
connections are required: a) blanketing gas supply
to valve, b) valve outlet to tank and c) sensing line
to tank.
