personnel when installing, operating and
maintaining the Type Y693 regulator.
Failure to follow these instructions or
to properly install and maintain this
equipment could result in an explosion,
fire and/or chemical contamination
causing property damage and personal
injury or death.
Scope of the Manual
This instruction manual includes installation, startup,
maintenance and parts information for the Type Y693
Gas Blanketing Regulator (Figure 1).
Fisher® regulators must be installed,
operated and maintained in
accordance with federal, state and
local codes, rules and regulations and
manufacturer’s instructions.
Product Description
The Accu-Pressure™ Type Y693 Gas Blanketing
Regulator (Figure 1) is a pressure reducing
regulator with external registration requiring a
downstream control line. It is used for accurate
pressure control on pressure blanketing systems.
The regulator will help in controlling emissions
from the blanketed product and helps in protecting
against any contamination to the blanketed product
by atmospheric conditions.
If the regulator vents gas or a leak
develops in the system, service to the unit
may be required. Failure to correct trouble
could result in a hazardous condition.
Installation, operation and maintenance
procedures performed by unqualified
personnel may result in improper

1. Use qualified personnel when installing, operating
and maintaining the regulator. Before installing,
inspect the regulator for any shipment damage or
foreign material that may have collected during
crating and shipment. Make certain the body
interior is clean and the pipelines are free of
foreign material. Apply pipe compound only to the
male pipe threads.

2. The regulator may be installed in any position as
long as the flow through the body is in the direction
indicated by the flow arrow attached to the body.
Install the regulator as close as possible to the
blanketed vessel using a straight run of pipe the
same size or larger as the regulator body. Position
the body (key 28) and/or diaphragm spring case
(key 23) so it will not collect moisture or debris
into the screened vent (as shown in Figure 2). If
the regulator requires repositioning, refer to the
body area maintenance procedures and/or the

procedures in the Maintenance section to

reposition the screened vent for the application.
If a block valve is required, install a full flow valve
between the regulator and the blanketed vessel.
Figure 2. Typical Type Y693 Installation
4. For proper regulator operation, a spring case vent
(key 56) is required to allow atmospheric pressure
to register on the diaphragm. The spring case vent
must be kept open and positioned in such a manner
to prevent the spring case from collecting moisture,
corrosive chemicals or other foreign material. To
allow maximum flexibility in installing the regulator,
the vent assembly is supplied separately in a
bag. Install the vent assembly in the 3/4 NPT vent
tapping and position the vent pointed down as
shown in Figure 2.
3. Attach a downstream pressure control line to the
female connection in the lower spring case. The
female pressure connection is a 1/2 NPT in the
steel or stainless steel lower spring case and
a 3/4 NPT for the aluminum lower spring case.
Connect the other end of the control line to the
vessel. To allow for self-drainage, install the control
line at an angle so that any liquid material will drain
away from the regulator. See Figures 4 and 5 for
the location of the external control line connection.
Depending on the orientation of the regulator, the
elbow (key 75) supplied with the vent may not be
required to position the vent pointed down.

indicates that service is required.
Failure to take the regulator out of
service immediately may create a
hazardous condition. In hazardous
or flammable gas service, vented gas
may accumulate and cause personal
injury, death or property damage due
to fire or explosion. Vent a regulator
in hazardous gas service to a remote,
safe location away from air intakes or
any hazardous location. The vent line
or stack opening must be protected
against condensation or clogging.
6. If continuous operation of the system is required
during inspection or maintenance, install a parallel
regulator with a three-valve bypass around
the regulator.

Type Y693
blanketing regulator remains open in response to the
decreasing downstream pressure. If vent valves are not
installed, safely bleed off both inlet and outlet pressures,
and check that the regulator contains no pressure.
Startup and adjustment
!
WaRnInG
To avoid personal injury, property
damage or equipment damage caused
by bursting of pressure containing parts
or explosion of accumulated gas, never
adjust the control spring to produce an
outlet pressure higher than the upper
limit of the outlet pressure range or that
particular spring (see Table 1). If the
desired outlet pressure is not within
the range of the control spring, install
a spring of the proper range according
to the Diaphragm and Spring Case area
section of the maintenance procedure.
Principle of Operation
The Type Y693 Gas Blanketing Regulator reduces a
higher-pressure gas to maintain a positive low pressure
of blanket gas over a stored liquid (see Figure 2). Also
when the vessel (or tank) is suddenly cooled, causing
vapors to contract, the regulator replaces the volume of
contracting vapors with a volume of blanketing gas to
prevent the internal vessel pressure from decreasing. In
both cases, a positive vessel pressure prevents outside
air from entering the vessel and reduces the possibility
of atmospheric pressure collapsing the vessel.
Gas blanketing regulators respond to a slight decrease
in internal vessel pressure (caused by pump out or
atmospheric cooling) by throttling open to increase the
flow rate of gas into the vessel. When the vessel’s liquid
level has been lowered to the desired point and the vapor
pressure reestablished, the regulator throttles closed.
With installation completed, the regulator can be
placed in operation by slowly opening the upstream
and downstream block valves, if used, while using
gauges to monitor pressure. The regulator takes
control when downstream pressure is established.
The regulator has been adjusted at the factory
to provide approximately the reduced pressure
requested. To ensure the correct pressure setting
always use a pressure gauge to verify the outlet
pressure setting. The range of allowable pressure
settings is stamped on the spring casing nameplate.
If a pressure setting beyond the stamped range is
required, install a spring with the desired range by
following the procedures for changing the spring and
diaphragm in the Maintenance section. To adjust the
pressure setting, perform the following steps (key
numbers are referenced in Figures 3, 4 and 5):
When the liquid level drops and vessel pressure
decreases below the setting of the control spring, the
spring force on the diaphragm opens the disk assembly
to supply the required flow of gas to the vessel. When
vessel pressure has been satisfied, outlet pressure tends
to increase slightly, acting on the diaphragm. When the
outlet pressure exceeds the control spring setting, the
diaphragm moves to close the disk assembly.
Maintenance
Regulator parts are subject to normal wear and
must be inspected and replaced as necessary. The
frequency of inspection and replacement of parts
depends upon the severity of service conditions
or the requirements of local, state and federal
regulations. Due to the care Emerson™ takes in
meeting all manufacturing requirements (heat treating,
dimensional tolerances, etc.), use only replacement
parts manufactured or furnished by Fisher®.
1. Remove the closing cap (key 3, if required).
2. Turn the adjusting screw (key 2) either clockwise
to increase outlet pressure or counterclockwise to
decrease outlet pressure. The regulator will go into
immediate operation. To ensure correct operation
always use a pressure gauge to monitor the
blanket pressure when making adjustments.
3. Replace the closing cap (key 3, if required).
Shutdown
!
WaRnInG
First, close the nearest upstream shutoff valve and
then, close the nearest downstream shutoff valve and
the block valve on the control line (refer to Figure 2).
Next, open the vent valve between the regulator and
the downstream shutoff valve nearest to it. Then, open
the upstream vent valve and the vent valve in the
control line. All pressure between these shutoff valves
is released through the open vent valves, since a gas
To avoid personal injury, property
damage or equipment damage caused by
sudden release of pressure, isolate the
regulator from all pressure and cautiously
release trapped pressure from the
regulator before attempting disassembly.
