The Specications section lists pressure limitations and other specications for various Types 1098-EGR and
1098H-EGR constructions. Specications for a given regulator as it originally comes from the factory are stamped
on nameplates located on both the actuator and main valve body, while the pilot control spring range is displayed
on the pilot spring case and the pilot restriction code is stamped on the pilot body (S = standard gain, L = low gain
and H = high gain). To determine maximum pressure ratings, the individual ratings for the main valve, actuator and
pilot must all be considered.

The pilot-operated Types 1098-EGR and 1098H-EGR
regulators both use inlet pressure as the operating
medium, which is reduced through pilot operation to
load the actuator diaphragm. Outlet or downstream
pressure opposes loading pressure in the actuator
and also opposes the pilot control spring. The
Type 1098- EGR regulator operation schematic is
shown in Figure 2.
In operation, assume that outlet pressure is below
the pilot control setting. Control spring force on the
pilot diaphragm opens the pilot valve plug providing
additional loading pressure to the actuator diaphragm.
This loading pressure forces the actuator stem
forward, opening the main valve plug via a bump
connection. The upward motion of the plug allows gas
to ow through the cage into the downstream system.
When downstream demand has been satised, outlet
pressure tends to increase, acting on the pilot and
actuator diaphragms. This pressure exceeds the pilot
control spring setting, moving the pilot diaphragm
away and letting the valve plug spring (Type 6351,
61 Series or Type Y600AM pilots) or bellows
(Types 6352 through 6354M pilots) close the pilot
valve plug (unbalanced in the Type 6351 or 61 Series
pilots but balanced in the Types 6352 through 6354M
pilots). Excess loading pressure on the actuator
diaphragm escapes downstream through the bleed
hole (Type 6351 pilot), bleed orice (61 Series pilot),
restriction (Types 6352 through 6354M pilots) or xed
restrictor (Type Y600AM pilot).
Reduced actuator loading pressure permits the main
valve to close. The combination of main valve spring
force and valve plug imbalance provides positive valve
plug shutoff against the port and upper seals.
To protect the Type 1098 or 1098H actuator diaphragm
from excessive differential pressure, the 6350 Series
pilots have an integral check valve that allows loading
pressure to bleed downstream at approximately
25 psig / 1.7 bar differential across the actuator
diaphragm. An external check valve (Type 1806)
is required when differential is higher than 25 psi /
1.7 bar or when using the 61 Series or Y600AM pilots.

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 regulator is
overpressured or is installed where service
conditions could exceed the limits given
appropriate nameplate 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 to
prevent service conditions from exceeding
those limits.
FIXED RESTRICTOR

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

(Figure 3)
Installations
A Type 1098-EGR or Type 1098H-EGR regulator
bleeds no gas to the atmosphere, making it suitable for
installation in pits or other enclosed locations without
elaborate venting systems. This regulator can also be
installed in pits subject to ooding by venting the pilot
spring case above the expected ood level so that the
pilot diaphragm is exposed to atmospheric pressure.

Normal pressure drop assists shutoff.
Therefore, leakage may result during any
reverse pressure drop condition.
1. Use qualied personnel when installing, operating
and maintaining regulators. Before installing,
inspect the main valve, pilot and tubing 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 with a screwed
body or use suitable line gaskets and good bolting
practices with a anged body.
With a weld end body, be sure to remove the trim
package, including the gasket, according to the
Maintenance section before welding the body into
the line. Do not install the trim package until any
post-weld heat treatment is completed. If heat
treating, prevent scale buildup on all machined
guiding and sealing surfaces inside the body and
at the bonnet ange/body joint.
2. The regulator maybe installed in any orientation,
as long as ow through the regulator matches the
direction of the ow arrow attached to the valve
body. However, mounting the main valve with the
valve stem in a horizontal position may experience
stem wear on units with a size 70 actuator or
NPS 4 and larger.
3. Install a three-valve bypass around the regulator
if continuous operation is necessary during
maintenance or inspection. The pilot may be eld-
changed to the opposite-side mounting position
by swapping the pilot pipe nipple to the opposite
bonnet tapping.
WARNING
!
A regulator may vent some gas to
the atmosphere. In hazardous or
accumulate and cause personal injury,
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.
4. To keep the pilot 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. To remotely
vent the standard pilot, remove the vent 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. Run a 3/8 in. / 9.5 mm outer diameter or larger
pilot supply line from the upstream pipeline to
the lter inlet as shown in Figure 3. Do not make
the upstream pipeline connection in a turbulent
area, such as near a nipple, swage or elbow. If
the maximum pilot inlet pressure could exceed the
pilot rating, install a separate reducing regulator in
the pilot supply line. Install a hand valve in the pilot
supply line and provide vent valves to properly
isolate and relieve the pressure from the regulator.
6. Attach a 1/2 NPT downstream pressure control
line downstream of the regulator in a straight run
of pipe, as shown in Figure 3. Do not make the tap
near any elbow, swage or nipple that might cause
turbulence. Connect the other end of the control
line to the bonnet connection. Install a hand valve
in the control line to shut off the control pressure
when the bypass is in use.
7. If a quick acting solenoid is to be installed
downstream of the regulator, the regulator
and solenoid should be located as far apart as
practical. This maximizes the gas piping volume
between the regulator and solenoid and improves
the regulator response to quick-changing
ow rates.
8. Consult the appropriate instruction manual for
installation of an optional Type 662 pneumatic
or electric remote control drive unit. For optional
remote pneumatic loading of a 6350 or 61 Series
pilot, make the loading piping connections to the
1/4 NPT vent connection.
Pre-startup Considerations
Before beginning the startup procedures in this section,
make sure the following conditions are in effect:
• Block valves isolate the regulator.
• Vent valves are closed.
• Hand valves are closed.
8
Page 9
Types 1098-EGR and 1098H-EGR
CAUTION
Introduce pilot supply pressure into
the regulator before introducing any
downstream pressure or internal damage
may occur due to reverse pressurization
of the pilot and main valve components.
Always use pressure gauges to monitor downstream
pressure during startup. Procedures used in putting
this regulator into operation must be planned
accordingly if the downstream system is pressurized
by another regulator or by a manual bypass.
Note
For proper operation, pilot supply
pressure must exceed control pressure
the actuator nameplate as minimum
differential pressure.
The only adjustment necessary on a Type 1098-EGR
or 1098H-EGR regulator is the pressure setting of
the pilot control spring. Turning the adjusting screw
clockwise into the spring case increases the spring
compression and pressure setting. Turning the
adjusting screw counterclockwise decreases the spring
compression and pressure setting.
Pilot Adjustment
To adjust standard 6350 Series pilots: Loosen the
locknut and turn the adjusting screw. Then tighten
the locknut to maintain the adjustment position.
On a standard Types 6352 through 6354M pilots,
closing cap must be removed before adjustment and
replaced afterward.
WARNING
!
To avoid possible personal injury from
a pressure-loaded pilot, carefully vent
the spring case before removing the
closing cap. Otherwise, trapped loading
pressure could forcefully eject the freed
closing cap.
To adjust the 61 Series or Type Y600AM pilots:
Remove the closing cap and turn the adjusting screw.
Any adjustments made should set the controlled
pressure within the appropriate spring range shown
in the Table 2.
Startup
1. Slowly open the pilot supply line hand valve.
2. Slowly open the upstream block valve and partially
open the downstream block valve for minimum
ow. Slowly open the hand valve in the
control line.
3. Adjust the pilot setting, if necessary.
4. Completely open the downstream block valve.
5. Slowly close the bypass valve, if any.
Dual-Pilot Boiler Fuel Control
Applications
To enhance proper operation and adequate response
to negative pressure shock condition in low differential
pressure boiler fuel control applications, use the
Type 1098-EGR boiler fuel conguration:
• Type 1098-EGR with Type 6352 pilot
• Size 70 Actuator
• Quick Opening Cage
• Yellow Main Spring
• Type Y600AM or 627M Auxiliary Pilot mounted in
parallel with the Type 6352 pilot
To provide faster response, two pilots mounted
in parallel sense the downstream pressure. The
Type 6352 pilot is the primary controlling pilot and
the Type Y600AM or 627M auxiliary pilot stands by
until it senses a negative pressure shock condition.
The auxiliary pilot opens, allowing additional ow
into the actuator, increasing the stroking speed and
providing faster response. See Figure 4 for schematic.
The quick-opening cage allows maximum capacity at
shorter travels to decrease stroking time in opening
and closing directions. The service conditions should
not exceed 20 psig / 1.4 bar maximum inlet pressure
and 10 psi / 0.69 bar maximum differential pressure.
If a pilot light is present, supply it gas with the
Type 1098- EGR. The pilot light gas supply line should
branch off the main fuel line downstream of the
Type 1098-EGR and include a separate regulator to
control the nal pilot light gas pressure, if required (see
Figure 5). This allows the Type 1098-EGR to have its
main valve plug just off the seat waiting for the sudden
negative shock created when the boiler solenoid
valve is opened to light the boiler to the high re load.
This installation practice signicantly increases the
stroking speed of the Type 1098-EGR. See Figure 5
for schematic.
9
Page 10
Types 1098-EGR and 1098H-EGR
Note
Modulating solenoid load valves provide
one position to the other, effectively
preventing sudden pressure changes in
the system. Alternately, a snap-acting
solenoid valve can be furnished with a
characterized valve plug that, by allowing
maximum capacity to be reached at a
greater proportion of total travel, slows
the action slightly. This action does
not control shock as effectively as
modulating solenoid valves.
Installation
1. Perform the Standard Single-Pilot Regulator
Installation section through step 4, making sure
that the regulator is installed with the actuator
below the main valve as shown in Figure 4.
2. Run a 1/2 in. / 13 mm or larger pilot supply line
from the upstream pipeline to the 1/2 NPT supply
connection in the pipe tee as shown in Figure 4. Do
not make the connection in a turbulent area, such as
near a nipple, swage or elbow. If the maximum pilot
inlet pressure could exceed the pilot rating, install
a separate regulator in the pilot supply line and
provide vent valves so that pressure can be properly
isolated and relieved from the regulator.
3. Slowly open the hand valve in the control line and
make sure that the standby pilot is set far enough
below the working pilot so that the standby pilot
remains closed during normal operation. For
example, with nal desired settings of 11 in. w.c. /
27 mbar for the working pilot and 10 in. w.c. /
25 mbar for the standby pilot, begin by reducing
the working pilot setting far enough below
10 in. w.c. / 25 mbar for the working pilot to
shut off. Then set the standby pilot for an outlet
pressure of 10 in. w.c. / 25 mbar. Finally, set the
working pilot for an outlet pressure of 11 in. w.c. /
27 mbar. Table 6 shows how close the standby
pilot can be set to the working pilot setting.
4. Completely open the downstream block valve.
3. Attach a 1/2 NPT downstream pressure control
line ten pipe diameters downstream of the
regulator in a straight run of pipe. Do not make
the tap near any elbow, swage or nipple, which
might cause turbulence. Connect the other end of
the control line to the 1/4 NPT connection in the
control pipe tee as shown in Figure 4. Install a
hand valve in the control line to shut off the control
pressure when the bypass is in use. Also use the
hand valve to dampen out pulsations, which may
cause instability or cycling of the regulator.
4. Consult the appropriate instruction manual for
installation of an optional pneumatic or electric
remote control drive unit. For optional remote
pneumatic loading of 6350 or 61 Series pilots,
make the loading piping connections to the
1/4 NPT vent connection.
Startup
1. Slowly open the pilot supply line hand valve.
2. Slowly open the upstream block valve and partially
open the downstream block valve for minimum ow.
5. Slowly close the bypass valve, if any.
Working Monitor (Figure 6)
Installation
1. For both working monitor regulator and working
regulator, perform the Standard Single-Pilot
Regulator Installation section through step 7.
2. Connect another downstream pressure control line
and hand valve (Figure 6) to the monitoring pilot
according to the monitoring pilot instruction manual.
Attach a 1/2 NPT pressure control line and hand
valve from the intermediate pressure pipeline to the
working monitor regulator. Pipe supply pressure
between the monitoring pilot and the working
monitor regulator according to the monitoring
pilot manual.
For two typical monitoring pilots, Table 7 gives
the spread between normal distribution pressure
and the minimum pressure at which the working
monitor regulator can be set to take over if the
working regulator fails to open.

Startup
On a working monitor installation (Figure 6), be sure that
the second-stage working regulator is set to operate at a
pressure lower than the Type 1098-EGR or 1098H-EGR
working monitor regulator. To do this, increase the setting
of the monitoring pilot until the working pilot is in control of
the intermediate pressure and the second-stage working
regulator is in control of the downstream pressure. If this
is not done, the monitoring pilot tries to take control of the
downstream pressure.
1. Slowly open the upstream block valve and
the hand valves in both pilot supply lines. This
energizes both pilots so that their setpoints can
be adjusted. Partially open the downstream block
valve for minimum ow.
2. To enable intermediate pressure adjustment with
the working monitor regulator, slowly open the
hand valve in the intermediate pressure control line.
3. To enable downstream pressure adjustment with
the second-stage working regulator, slowly open
the hand valve in the control line to this regulator.
4. Adjust the setting of the monitoring pilot to
establish the desired emergency downstream
pressure, which is to be maintained in the event
of open failure of the second-stage working
regulator. The emergency downstream pressure
should exceed the desired downstream pressure
by at least the amount listed in Table 7. The steps

Wide-Open Monitor (Figure 7)
Either the upstream or downstream regulator can be
the monitor regulator. During normal operation, the
monitoring regulator is standing wide open with the
reduction to distribution pressure being taken across
the working regulator. Only in case of open failure of
the working regulator does the wide open monitoring
regulator take control at its slightly higher setting.
Note that if using a downstream monitor setup, the
upstream worker regulator actuator must be rated to the
application’s full inlet pressure or be protected from it in
case it fails wide-open.
Regardless of which regulator is used as the monitor, it
should be equipped with a pilot supply regulator set to
5 psig / 0.34 bar plus the monitor minimum differential
presure above the working regulator pressure setting.
Since the pilot on the monitoring regulator is wide open
during normal operation, the pilot supply regulator
prevents differential check valve chatter on the
monitoring regulator pilot.
Adjustment Recommendations for
Monitor Applications
Low amplitude/high frequency monitor trim oscillations
can occur if the monitor regulator pressure setting is
adjusted too closely to the working regulator pressure
setting and/or if the monitor pilot supply regulator
pressure setting is adjusted too closely to the monitor
regulator pressure setting. The monitor pressure
setting should be adjusted so it is at minimum two
times the pilot proportional band pressure above
the working regulator pressure setting. These
adjustments must be made such that other governing
pressure limits, such as casing ratings, pilot maximum
differential pressures or regulatory limits, are
not exceeded.
Installation
1. For both the wide-open monitoring regulator
and the working regulator, perform the Standard
Single-Pilot Regulator Installation section through
step 7.

2. Connect the control line of the wide-open
monitoring regulator (Figure 7) to downstream
piping near the working regulator control
line connection. During normal operation the
wide- open monitoring regulator stands wide-open
with the pressure reduction being taken across
the working regulator. Only in case of working
regulator failure does the wide-open monitoring
regulator take control at its slightly higher setting.
Startup
Repeat this procedure in turn for each regulator in
the installation.
1. Slowly open the pilot supply line hand valve.
2. Slowly open the upstream block valve and
partially open the downstream block valve for
minimum ow.
3. Slowly open the hand valve in the control line
and adjust the pilot setting if necessary. Set the
monitoring regulator at a slightly higher control
pressure than the working regulator.
4. Completely open the downstream block valve.
5. Slowly close the bypass valve, if any.
Shutdown
Installation arrangements vary, but in any installation it
is important that the valves be opened or closed slowly
and that the outlet pressure be vented before venting
inlet pressure to prevent damage caused by reverse
pressurization of the pilot or main valve. The following
steps apply to the typical installation as indicated.
Single-Pilot, Dual-Pilot Regulator or
Wide-Open Monitor
As well as applying to a single-pilot regulator (Figure 3),
the steps in this procedure are also valid for a dual- pilot
regulator (Figure 4) or a wide-open monitoring
installation (Figure 7) and just need to be repeated for
each regulator in such an installation.
1. Slowly close the downstream block valve. If the
control line is downstream of the block valve, also
close the hand valve in the control line.
2. Slowly close the upstream block valve and the
hand valve in the pilot supply line.
3. Slowly open the vent valve in the downstream
pipeline. If the control line is downstream of the
block valve, also open the vent valve in the control
line. Permit all pressure to bleed out.
4. Slowly open the upstream pipeline vent valve.
Allow all pressure to bleed out of both the piping
and the pilot.

2. Slowly close the upstream block valve and the
hand valves in both pilot supply lines.
3. Slowly open all vent valves and permit all pressures
to bleed out of the piping and regulators.
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 Emerson.
The stem O-rings (key 6, Figure 13) on the Type 1098
or 1098H actuator should be lubricated during regularly
scheduled maintenance, using the grease tting
(key 28, Figure 13). Stem O-rings can be checked
for damage during normal operation by line pressure
leakage or unexpected grease extrusion from the
actuator vent (key 27, Figure 13). Unless otherwise
speci ed, all O-rings, gaskets and seals should be
lubricated with a good grade of general-purpose
grease and installed gently rather than forced into
position. Be certain that the nameplates (key 13,
Figure 13) are updated to accurately indicate any eld
changes in equipment, materials, service conditions or
pressure settings.
WARNING
!
To avoid personal injury resulting
from sudden release of pressure,
isolate the regulator from all pressure
and cautiously release trapped
pressure from the regulator before
attempting disassembly.

lower spring seat (key 50) and washer (key 36) and
secure with diaphragm cap screw (key 38) using 7 to
9 ft-lbs / 9.5 to 12 N•m of torque.
8. Install the pusher post (key 8) and attached parts
onto the lever (key 16).
9. Install the control spring (key 6) and spring case
(key 3) on the diaphragm casing (key 4) so that the
vent assembly (key 26) is correctly oriented and
secure them with the cap screws (key 24) and hex
nuts (key 23) to nger tightness only.
10. Turn the adjusting screw (key 35) clockwise until
there is enough control spring (key 6) force to provide
proper slack to the diaphragm (key 10). Using a
crisscross pattern, nish tightening the cap screws
(key 24) and hex nuts to 5 to 6 ft-lbs / 6.8 to 8.1 N•m
of torque. Finish turning the adjusting screw to the
desired outlet pressure setting.
11. Install the closing cap (key 22).
Type MR95H Supply Pressure Regulator
This section includes instructions for disassembly and
assembly of replacement parts. All key numbers refer
to Figure 22.
1. Unscrew the valve plug guide (key 5) from the
body (key 1). The valve plug spring (key 10) and
the valve plug (key 4) will normally come out of the
body along with the valve plug guide.
2. Inspect the seating surface of the valve plug (key 4),
being sure that the composition surface (or polished
steel surface) of the valve plug is not damaged.
Replace if damaged.
3. Inspect the seating edge of the orice (key 3).
If damaged, unscrew the orice from the body
and replace it with a new part. If no further
maintenance is required, reassemble the regulator
in the reverse of the above steps. When installing
the valve plug guide (key 5) coat the threads
and sealing surface with sealant to ensure an
adequate metal-to-metal seal.

Types 1098-EGR and 1098H-EGR
4. To inspect the diaphragm (key 12) or other
internal parts, loosen the locknut (key 17) and
turn the adjusting screw (key 15) to remove all
spring compression.
5. Remove the diaphragm case cap screws (key 16)
and lift off the spring case (key 2). Remove the
upper spring seat (key 9) and regulator spring
(key 11). Remove the lower spring seat (key 8).
6. Remove the diaphragm (key 12) and examine for
damage. Replace if damaged.
7. With diaphragm removed, check to be sure the
pressure registration hole is completely open and
free of all obstructions.
8. Reassemble in reverse order of the previous steps.
Lubricate the upper spring seat (key 9) and the
exposed threads of the adjusting screw (key 15).
Before tightening cap screws (key 16) be sure to
install the adjusting screw, if completely removed and
turn it down to obtain diaphragm slack. This allows
proper positioning of the diaphragm to permit full
travel of the valve plug (key 4). Complete reassembly
procedures and temporarily install a gauge in place
of the pipe plug (key 52). Turn the adjusting screw to
produce the desired outlet pressure values shown
in Table 2. Tighten the locknut to maintain the
desired setting.
Types 1098 and 1098H Actuator and
Pilot Mounting Parts
Perform this procedure if changing the actuator or
inspecting, cleaning or replacing actuator and/or
pilot mounting parts. Actuator part key numbers are
referenced in Figure 13 and mounting part numbers in
Figure 26, unless otherwise indicated.
1. The actuator and pilot(s) may be removed and
replaced as a unit by disconnecting the control line
and pilot supply line.
2. Access to all internal parts except the stem
O-rings, bearings and wiper (keys 6, 56 and 57)
may be gained without removing the bonnet
(key 3) or upper diaphragm case (key 2) from
the main valve or the pilot(s) from the bonnet
pipe nipple (key 23, Figure 23 or keys 37 and 39,
Figure 27). Disconnect the loading tubing (key 24,
Figure 23, 25 or 27) from the actuator elbow tting
(key 25, Figure 23 or key 41, Figure 27) and with
a Type 61LD pilot also disconnect the tubing
(key 18, Figure 24) from the tting tee.
3. Remove the cap screws (key 10), nuts (key 11),
lower diaphragm case (key 1), diaphragm (key 7)
and diaphragm plate (key 8). To separate the stem
(key 12) from the diaphragm plate (key 8), remove
the stem cap screw (key 9).
4. To remove the Type 1098 case O-ring (key 5),
unscrew the four case cap screws (key 4),
remove the upper diaphragm case (key 2) and
remove the case O-ring.
To remove the Types 1098 and 1098H stem
O-rings (key 6), remove the pilot(s) and pipe
nipple(s) if necessary. Unscrew either the
Type 1098 bonnet (key 3) or the Type 1098H
upper diaphragm case (key 2) and remove the
wiper ring, bearings and O-rings.
5. Lubricate both stem O-rings (key 6) and
wiper ring (key 57) and install them with the stem
bearings (key 56) in either the Type 1098 bonnet
(key 3) or in the Type 1098H upper diaphragm
case (key 2).
6. For the Type 1098H actuator, thread the upper
diaphragm casing (key 2) into the main valve body.
For the Type 1098 actuator, lubricate the case
O-ring (key 5) and install it in the bonnet (key 3). Line
up the holes in the upper diaphragm casing (key 2)
and the bonnet; insert and tighten the four case cap
screws (key 4) to secure the parts together. Thread
the bonnet into the main valve body.
7. Secure the diaphragm plate (key 8) to the stem
(key 12) with the stem cap screw (key 4). Lay the
entire diaphragm (key 7), diaphragm plate and
stem assembly into the lower diaphragm case
(key 1) so the diaphragm convolution laps up
over the diaphragm plate according toFigure 13.
Then install the stem slowly up into the bonnet
(key 3) to prevent stem or O-ring damage and
secure the lower diaphragm case to the upper
diaphragm case (key 2) with the cap screws
and nuts. Tighten the cap screws and nuts
evenly in a crisscross pattern to avoid crushing
the diaphragm.
8. Grease the stem O-rings through the zerk tting
(key 28) until excess grease emerges from the
vent (key 27).
9. Install the pipe nipple(s) and pilot(s) if they were
removed during maintenance. Connect the
actuator loading tubing if it was disconnected.
