Introduction

Scope of the Manual

This instruction manual provides installation, startup,
maintenance, and parts ordering information for the
Type Y692 Low-Pressure Gas Blanketing Regulator.

W5930

Figure 1. Type Y692 Low-Pressure Gas Blanketing Regulators

operated regulator with internal registration or external
pressure registration. It is used for accurate pressure
control on very low-pressure blanketing systems.
Blanketing with low-pressure gas helps prevent
corrosion, helps control emissions from the blanketed
product and helps protect against any contamination to
the blanketed product by atmospheric conditions.

The regulator will maintain a positive vessel
pressure reducing the possibility of vessel wall
collapse. The Type Y692 is available in NPS 1-1/2
and 2 (DN 40 and 50) body sizes.

Type Y692 with external pressure registration
regulators have a stem seal with O-rings and a
1/2 NPT control line connection in the diaphragm
case. The control line can be used to more accurately
control the pressure in the tank if the regulator is
mounted an extended distance from the control point.
The stem seal separates the body outlet pressure from
the diaphragm case.

Principle of Operation

The Type Y692 Gas Blanketing Regulator reduces a
high-pressure gas to maintain a positive low-pressure
of blanket gas over a stored liquid when the liquid is
being pumped out of the vessel (see Figures 2 and

3). 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 by throttling open to

increase the ow rate of gas into the vessel. When the

vessel’s liquid level has been lowered to the desired
point and the vapor pressure re-established, the
regulator throttles closed.

DOWNWARD

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 ow of gas to the
vessel. When vessel pressure has been satised,

control pressure tends to increase slightly, acting on
the diaphragm. When the control (vessel) pressure
exceeds the control spring setting, the diaphragm
moves to close the disk assembly.

The Type Y692 Gas Blanketing Regulator provides
a constant set pressure for accurate gas blanketing.
When vessel pressure decreases below the control
spring setpoint, the force of the spring moves the disk

away from the orice allowing gas to ow into the

vessel. As the vessel pressure increases, the increase
is sensed by the diaphragm through the pitot tube or
control line. This movement of the diaphragm causes

the disk to move toward the orice, decreasing the
ow of blanketing gas. When the vessel pressure

reaches the system setpoint, the disk will seat against

the orice shutting off the ow of gas.

Installation

WARNING

!

Personal injury, equipment damage, or
leakage due to escaping accumulated
gas or bursting of pressure-containing
parts may result if the gas blanketing
regulator is overpressured or installed
where service conditions could exceed

the limits given in Specications

section, or where conditions exceed
any ratings of the adjacent piping or
piping connections. To avoid such
injury or damage, provide pressure­relieving 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 Association, or by other
applicable codes) to prevent service
conditions from exceeding those limits.

Additionally, physical damage to the
gas blanketing regulator could result in
personal injury and property damage
due to escaping accumulated gas. To
avoid such injury and damage, install
the gas blanketing regulator in a safe
and well ventilated location.

1. Use qualied 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
external pipe threads.

2. To achieve the published capacities, 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. Flow through the

regulator body is indicated by the ow arrow cast

on the body. If a block valve is required, install a full

ow valve between the regulator and the blanketed

vessel. For proper operation, the regulator
must be installed with the spring case barrel
pointed down (as shown in Figures 2 and 3).

Key numbers referenced in this section are shown

in Figure 6.

WARNING

!

If the regulator vents some gas or a leak
develops in the system, it indicates that
service is required. Failure to take the
regulator out of service immediately
may create a hazardous condition. In

hazardous or ammable gas service,

vented gas may accumulate, and cause
personal injury, death, or property damage

due to re 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.

3. To keep the spring case vent from being plugged
or the spring case from collecting moisture,
corrosive chemicals, or other foreign material,
point the vent down or otherwise protect it.

4. To remotely vent the regulator, remove the vent
(key 56) and install obstruction-free tubing or
piping into the 1/4 NPT vent tapping. Provide
protection on a remote vent by installing a
screened vent cap into the remote end of the
vent pipe.

5. If continuous operation of the system is required
during inspection or maintenance, install a parallel
run with a three-valve bypass around the regulator.

For Types with external pressure registration which
require a downstream control line, be sure to install the
control line before putting the regulator into operation.
The control line pipe should be at least 1/2-inch
(13 mm) in diameter and connected to a straight
section of outlet piping 5 to 10 pipe diameters
downstream of the regulator. If turbulence exists, a
hand valve can be installed in a straight section of the
control line. This hand valve can be throttled down to
dampen out pulsations which may cause instability or
cycling of the regulator. If a block valve is required,

install a full ow valve between the regulator and the

blanketed vessel.

Startup and Adjustment

WARNING

!

To avoid personal injury, property
damage, or equipment damage caused

4

Type Y692

by bursting of pressure containing parts
or explosion of accumulated gas, never
adjust the control spring to produce a
control pressure higher than the upper
limit of the control pressure range or

that particular spring (see Specications

section). If the desired control 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.

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 control pressure requested.
To ensure the correct pressure setting always use a
pressure gauge to verify the 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 Figure 6):

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.

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 care Emerson Process Management Regulator
Technologies, Inc. takes in meeting all manufacturing
requirements (heat treating, dimensional tolerances,
etc.), use only replacement parts manufactured
or furnished by Emerson Process Management
Regulator Technologies, Inc.

WARNING

!

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.

Key numbers are referenced in Figure 6.

1. Remove the closing cap (key 3, if required).

2. Turn the adjusting screw (key 2) either clockwise
to increase control pressure or counterclockwise
to decrease control 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

Installation arrangements vary, but in any installation
it is important to open and close valves slowly and

to close the upstream block valve rst when shutting

down the system.

First, close the nearest upstream block valve and then,
close the nearest downstream block valve to vent the
regulator properly. Next, open the vent valve between
the regulator and the downstream block valve nearest
to it. Then, open the upstream vent valve and the
vent valve in the control line. All pressure between
these block valves is released through the open vent
valves, since a gas blanketing regulator remains open

Body Area

This procedure is for gaining access to the disk

assembly, orice, body gasket, split ring, and pitot

tube if used. All pressure must be released from the
regulator, before these steps can be performed.

1. Unscrew the union nut (key 19) from the body
(key 28) and remove the lower casing assembly
(key 20) and split ring (key 17). The lower casing
assembly (key 20) must be tipped toward the
body outlet to allow removal clearance for the
pitot tube (key 74).

2. Inspect and replace the orice (key 27) if

necessary. Lubricate the threads of the

replacement orice with a good grade of
pipe thread sealant. Install the orice with
75 to 100 foot-pounds (102 to 136 N•m)

of torque.

3. Remove the cotter pin (key 14) if it is necessary to

replace the disk assembly (key 25).

4. To replace the pitot tube (key 74) on units with

internal pressure registration, remove the

ared end connection and press a new pitot tube

5

Type Y692

into the pitot tube hole and secure by aring the

end. Rotate the pitot tube so that it points into the
outlet of the body (key 28) after the lower casing
assembly (key 20) is installed.

5. Install the disk assembly (key 25) and secure it
with the cotter pin (key 14).

6. If necessary, install a replacement body gasket
(key 16) into the body (key 28).

7. Slide the union nut (key 19) as far as it will go
onto the lower casing assembly (key 20). Install
both halves of the split ring (key 17) into the slots
of the lower casing assembly (key 20) and secure
them by sliding the union nut down on the split ring.

8. Install the lower casing assembly (key 20) with the
attached split ring (key 17) and union nut (key 19)

so that the pitot tube ts into the outlet of the body.

9. Tighten the union nut (key 19) until the lower
casing assembly (key 20) is secure on the
body (key 28).

Diaphragm and Spring Case Area
