Principle of Operation
ACE95 Series tank blanketing valves are pilot
operated, activated by the diaphragm, and control the
vapor space pressure over a stored liquid. The unit
is controlled by a very large diaphragm actuator. The
oversized actuator offers high sensitivity to changes
in tank pressure. When a storage tank cools and
2

tank vapors condense, ACE95 Series valves replace
the condensing vapors with an inert gas to prevent
internal tank pressure from decreasing. Positive tank
pressure prevents outside air from contaminating the
product and reduces the possibility of atmospheric
pressure collapsing the tank. As demand is satisfied,
the valve closes.

Figure 3.  ACE95 Series Operational Schematic (valve open)

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 setpoint is re-established,
the valve closes.

Installation and Startup
!

Warning

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 overpressured 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 connections.
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
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.

Figure 4.  ACE95 Series Tank Blanketing Valve Installation

This ACE95 Series 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.  Use 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 threaded
body, or use suitable line gaskets and good bolting
practices with a flanged body.

the tank. Three connections are required:
a) blanketing gas supply to valve, b) valve outlet to
tank, and c) sensing line to tank.

Piping Considerations
caution
Undersized piping may inadequately
deliver blanketing gas at the specified inlet
pressure under full flow conditions. This
may result in unacceptable performance
under high demand conditions.
Unnecessarily long or restricted outlet
piping may result in poor setpoint control.

  2.  Inspect the nameplate on the upper actuator case.
It displays the model number, serial number,
a blanketing gas supply pressure range, and
the maximum inlet pressure and set pressure.
These must agree with the system that you are
blanketing. The serial number will be needed in any
communication with your local Sales Office.

Inlet Piping

  3.  Clean the gas blanketing supply lines of all dirt and
foreign material before connecting them to the
ACE95 Series tank blanketing valve.

Outlet Piping

  4.  The valve must be mounted so the actuator case
is horizontal. The valve should be mounted above
4

The blanketing gas supply line should be equipped with
a Number 100 mesh strainer to remove dirt and pipe
scale. Inlet piping must be sized to adequately deliver
blanketing gas at the specified inlet pressure under full
flow conditions.

Type ACE95 or Type ACE95Sr valve outlet is piped
into the tank vapor space. Outlet piping must be full
size and self-draining to the tank. The valve should
be situated above and as close as possible to the tank
vapor space for best performance.

ACE95 Series
Sensing Line
adjusting screw
(key 2)

The sensing line should be 1/2-inch (13 mm) tubing
or pipe, must slope down toward the tank, and should
not contain low points (or traps) that could catch liquid.
The sensing line must enter the tank above the liquid
level at a point that senses the vapor space pressure
and is free from turbulence associated with tank
nozzles or vents.

the tank has only one available nozzle,
contact Emerson® for alternate methods
of installation. A single array manifold is
available for such situations.

Gauges and Shutoff Valves
Inlet gas shutoff valves are desirable for servicing.
If this ACE95 Series tank blanketing valve was not
ordered with an inlet pressure gauge, it is advisable to
install a gauge between the inlet shutoff valve and the
blanketing valve.
Note
Safety considerations may dictate full
port shutoff valves between the tank and
blanketing valve, and at the valve inlet.

Startup, Adjustment, and Shutdown
Note
Tank vents and safety relief valves must
be in place and operating.

caution
Always open the outlet valve before the
inlet valve. Operation in the reverse
order could result in inlet pressure being
applied to the actuator casing, potentially
damaging it.

Startup
  1.  Open shutoff valves between the blanketing valve
and the tank (both sensing and outlet). See Figure 4.
  2.  Slowly open the supply line shutoff valve (to the
blanketing valve) and leave it fully open.
  3.  Monitor the tank vapor space pressure.

Adjustment
The setpoint of this unit is factory set. If an adjustment
is to be made, it should be done so in small increments
while the unit is supplying gas to the tank. To change
the setpoint:
  1.  Unscrew and remove the actuator cap (key 1) from
the top of the spring case (key 7). See Figure 5.
  2.  Loosen the lock nut (key 3) and turn the adjusting
screw (key 2) clockwise to raise the setpoint.
(Turning the screw counter-clockwise lowers
the setpoint.)
  3.  Observe the effects of the change.
  4.  When the adjustment is complete, tighten the lock
nut (key 3) and replace the actuator cap (key 1).

Shutdown
Installation arrangements vary, but in any installation
it is important to open and close valves slowly and to
close the upstream shutoff valve first when shutting
down the system.

Diagnostics
Note
If a diagnostics pressure gauge was not
ordered with the unit, a pressure gauge
must be installed in the diagnostic port
to perform diagnostic analysis.

ACE95 Series
Diagnostics are an optional feature of the ACE95 Series
Tank Blanketing valves that aid in evaluating valve
operation. The diagnostic analysis relies on the
relationship of pilot pressure and pressure in the main
valve chambers (see Figure 3). The basic relationships
are as follows:
In order to evaluate a valve, examine the valve
nameplate to determine the Cv and inlet pressure
range main valve spring. The inlet pressure gauge
indicates actual pressure supplied to the valve.
Follow these steps and refer to the diagnostics tables
on the following pages to evaluate a valve under
actual operating conditions:
  1.  Select the Table (Tables 3 through 8) that
corresponds to the Cv and inlet pressure range of
your valve.
  2.  Determine the actual valve operating inlet
pressure in the first column of the diagnostics table.
Table 2. Diagnostic Analysis Pressure Ranges
DIAGNOSTIC
(PRESSURE CHAMBER)

STATUS

Equal to inlet supply pressure

Pilot and main valves are closed.
Tank at or above set pressure.

Slightly below inlet supply pressure

Pilot valve supplies gas to tank.
Tank pressure is just below
set pressure.

Well below inlet supply pressure

Pilot and main valves are both
supplying gas to the tank. Tank
pressure is below setpoint.

  3.  In the second column of the table, determine the
pressure of the pilot as it opens.

Pressure to Start Opening Main Valve: The
diagnostic pressure drops to this level as the tank
pressure decreases and reaches the valve setpoint.
The pilot is fully open at this pressure.
Pressure to Fully Open Main Valve: At this point,
both the main valve and pilot valve are fully open and
supplying gas to the tank.

Maintenance
Valve parts are subject to normal wear and must be
inspected and replaced as necessary. The frequency
of inspection and replacement of parts depends on the
severity of service conditions and the requirements
of local, state, and federal regulations. Due to the
care Emerson® takes in meeting all manufacturing
requirements, use only replacement parts
manufactured or furnished by Emerson.
All O-rings, gaskets, and seals should be lubricated with
a good grade of general purpose lubricant and installed
gently rather than forced into position. Suggested
lubricant, sealant, and adhesive are as follows:
   Lubricant: Dow Corning® 111 or equivalent
   Sealant: Loctite® PST #592,
Polytetrafluoroethylene (PTFE) Tape or equivalent
   Adhesive: Loctite #222 or equivalent
Be certain that nameplates are updated to accurately
indicate any field changes in equipment, materials,
service conditions, or pressure settings.

Monthly Maintenance

  4.  Determine the diagnostic pressure for the start to
open pressure of the main valve in the third column.

  1.  Visually inspect the unit to ensure tight connections,
tight seals, and safe operation.

  5.  The fourth column displays the diagnostic
pressure for the full open pressure of the main valve.

  2.  Observe the blanketing pressure.

There are four pressures involved in evaluating a
valve: actual inlet pressure, pressure to start opening
pilot valve, pressure to start opening main valve, and
pressure to fully open main valve.
Actual Inlet Pressure: The gas pressure supplied
to the inlet of the valve. This is the maximum
diagnostic pressure.
Pressure to Start Opening Pilot Valve: The
diagnostic pressure drops to this value as the valve
senses decreasing tank pressure. The main valve
remains closed at this pressure.

6

  3.  Inspect the inlet pressure for the proper pressure
range (stamped on the valve nameplate).

Annual Maintenance
  1.  Visually inspect the unit to ensure tight connections,
tight seals, and safe operation.
  2.  Observe the blanketing pressure.
  3.  Inspect the inlet pressure for the proper pressure
range (stamped on the valve nameplate).
  4.  Visually inspect valve for any external wear.
  5.  If there is evidence of leakage or unstable
internal motion, a rebuild with seal replacement
and relubrication may be in order.

Disassembly and Assembly
caution
Before removing the valve from the line,
ensure that it is isolated from the gas
supply pressure and that all pressure
has been released from the valve. (The
drain on the inlet filter is convenient
to bleed off gas.) All tank connections
must be closed or sealed in accordance
with your plant’s operating and safety
procedures. If installed, electrical
connections to the explosion proof
switch must be deactivated before
opening the enclosure or disconnecting
the wiring (in accordance with codes
and safety practices).
It is recommended that all seals and diaphragms be
replaced as a matter of good practice whenever a
valve is disassembled and re-assembled. Parts kits
are available through your local Sales Office.
If you are performing disassembly or assembly operations
on a Type ACE95Sr valve, refer to the Parts List and see
Figure 9. If you are working on a Type ACE95 valve, refer
to the Parts List and see Figure 8.

Assembly
When assembling the Type ACE95 or Type ACE95Sr
tank blanketing valve, clean all parts, inspect for unusual
wear, and lightly lubricate all O-rings and the groove that
locates the rolling diaphragm bead. See Figures 8 and 9.

Bonnet Sub-Assembly
Prepare the bonnet (key 17) by installing two (2)
internal O-rings (key 16).

Pilot/Cage Sub-Assembly
Refer to Figures 6, 8, and 9 when performing pilot/cage
sub-assembly operations.
  1.  Apply Loctite® #222 or equivalent to the piston
threads. Place the rolling diaphragm (key 38)
over the threaded portion of the piston (key 37).
Position the bead as shown in Figure 6.
  2.  Thread the poppet (key 42) onto the piston
(key 37). Use soft-jawed pliers to restrain the
piston so it is not damaged. Do not hold the poppet
by the poppet stem. Insert a small drill bit into the
cross-drilled hole on the poppet stem (key 42) to
turn and tighten.
  3.  Slide the O-ring (key 39) onto the poppet (key 42).

  4.  Place the pilot sub-assembly into the upper
cage (key 40).
  5.  Press the lower cage (key 35) and upper cage
(key 40) together to ensure the groove in the lower
cage engages the bead on the rolling
diaphragm (key 38).
Note
Ensure that the rolling diaphragm bead
is positioned so that it sits in the groove
of the lower cage (see Figures 8 and 9).
If it does not, the rolling diaphragm
was installed upside-down in Cage
Sub-Assembly step 2.
  6.  Remove the lower cage (key 35).
  7.  Lubricate the piston (key 37) and lower cage
(key 35) groove.
  8.  Install the pilot spring (key 36) into the piston
(key 37) and re-install the lower cage (key 35).
  9.  Hold the pilot sub-assembly together and insert it
into the bonnet (key 17). Press firmly (the bonnet
O-rings will offer resistance).
  10.  Press the poppet stem. It should freely move up
and down. If it does not, repeat the procedure to
this point to determine the cause.
