Description
Types 1098-EGR and 1098H-EGR regulators provide
economical and accurate pressure control in a
wide variety of applications; natural gas distribution
systems; fuel gas supply to industrial boilers, furnaces,
ovens, and mixers; and large commercial/industrial
establishments such as shopping centers and schools.
They are also used in plant air service and in liquid
service where a slow stroking time (approximately
30 to 90 seconds) is desired on both opening and
closing the main valve.
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).
Principle of Operation
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 thus 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.
40 PSI (2,8 bar) Relief Valve
A mounting assembly for a 40 psi (2,8 bar) differential
relief valve is available for the Type 1098-EGR. The
standard 25 psi (1,7 bar) differential relief valve
construction is integrally mounted between the loading
and downstream pressures in the 6351 through
6354 Series regulating pilots. Both differential relief
valves protect the main regulator diaphragm from
damage that may occur from too high differential
between the loading pressure and downstream pressure.
The 40 psi (2,8 bar) differential relief valve construction
is designed specically for the red main valve spring
selection in the 6-inch (DN 150) Type 1098-EGR-6354
with the size 30 actuator. This construction uses the
Type 1806H relief valve (with a setting of 40 psi
(2,8 bar)) to relieve excess loading pressure and does not
interfere with the normal operation of the regulator.
Installation and Startup
WARNING
!
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
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 pilot). 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 unbalance 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 6300 Series
pilots have a relief valve that allows loading pressure to
bleed downstream at approximately 25 psig (1,7 bar)
differential across the actuator diaphragm. An external
relief valve (Type 1806) is required when differential is
higher than 25 psid (1,7 bar d) or when using the
61 or Y600A Series pilots.
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
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 to prevent service conditions from
exceeding those limits.
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.
Standard Single-Pilot Regulator
(Figure 3)
Installations
A Type 1098-EGR or 1098H-EGR regulator bleeds
no gas to the atmosphere, making it suitable for
installation in pits or other enclosed locations without
6
Types 1098-EGR and 1098H-EGR
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.
Note
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 male 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
build-up on all machined guiding and sealing
surfaces inside the body and at the bonnet
ange/body joint.
Note
the valve body.
2. 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.
3. 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-inch NPT vent tapping. Provide
protection on a remote vent by installing a screened
vent cap into the remote end of the vent pipe.
4. Run a 3/8-inch (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.
5. Attach a 1/2-inch 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 shutoff the control pressure when the bypass is
in use.
6. 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.
7. 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-inch NPT vent connection.
Prestartup 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.

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

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 pilot, a 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.
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

the downstream pressure. The Type 6352 pilot is
the primary controlling pilot and the Type Y600AM

pilot opens, allowing additional ow into the actuator,
increasing the stroking speed and providing faster

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

Figure 5. Boiler Fuel Conguration
Supply the boiler pilot light 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 low re load. This installation
practice signicantly increases the stroking speed of
the Type 1098-EGR. See Figure 5 for schematic.
1. Perform the Standard Single-Pilot Regulator
Installation section through step 3, making sure
that the regulator is installed with the actuator
below the main valve as shown in Figure 4.
2. Run a 1/2-inch (13 mm) or larger pilot supply
line from the upstream pipeline to the 1/2-inch
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. Attach a 1/2-inch 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-inch NPT connection in the control
pipe tee as shown in Figure 4. Install a hand
valve in the control line to shutoff 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 a 6350 or

connections to the 1/4-inch 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.
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-inches w.c. (27 mbar) for the working pilot
and 10-inches w.c. (25 mbar) for the standby
pilot, begin by reducing the working pilot setting
far enough below 10-inches w.c. (25 mbar) for
the working pilot to shutoff. Then set the standby
pilot for an outlet pressure of 10-inches w.c.
(25 mbar). Finally, set the working pilot for an
outlet pressure of 11-inches w.c. (27 mbar).
Table 6 shows how close the standby pilot can be
set to the working pilot setting.

Figure 7. Typical Working Monitor Installation
On a working monitor installation (Figure 7), 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

should exceed the desired downstream pressure
by at least the amount listed in Table 7. The steps
followed to set the monitoring pilot may vary with
each piping situation; however, the basic method
remains the same. The following sub steps a
and b may be used as examples for setting the
monitoring pilot:
a. Increase the outlet pressure setting of the
second-stage working regulator until the
monitoring pilot takes control of the downstream
pressure. Adjust the monitoring pilot setting
until the desired emergency downstream
pressure is achieved. Then, readjust the second-
stage working regulator to establish the desired
downstream pressure.
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

b. Install special piping (not shown in
Figure 7) so that the monitoring pilot senses
the intermediate pressure. The intermediate
pressure then appears to the monitoring pilot as
if it were increased downstream pressure,
and the monitoring pilot controls and reduces
the intermediate pressure. Adjust the monitoring
pilot setting until the desired emergency
downstream pressure is achieved at the
intermediate pressure stage. Then slowly
close the special piping, and open up the
monitoring downstream control line for
normal service.

NOTICE
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 2
times the pilot proportional band pressure above the
working regulator pressure setting. The monitor pilot
supply pressure setting should be adjusted so it is at
minimum 5 psig (0,34 bar) plus the monitor minimum
differential 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.
MINIMUM PIPING WIDE-OPEN MONITOR ARRANGEMENT THAT
REQUIRES WIDE-OPEN MONITOR ALWAYS TO BE UPSTREAM
Wide-Open Monitor (Figure 8)
Installation
1. For both the wide-open monitoring regulator and
the working regulator, perform the Standard
Single-Pilot Regulator Installation section
through step 6.
2. Connect the control line of the wide-open
monitoring regulator (Figure 8) 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.

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 also are valid for a dual-
pilot regulator (Figure 4), or a wide-open monitoring
installation (Figure 8) 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.

1. Slowly close the downstream block valve and the
hand valve in the downstream pressure control line.
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
Fisher® takes in meeting all manufacturing requirements
(heat treating, dimensional tolerances, etc.), use only
replacement parts manufactured or furnished by Fisher.
The stem O-rings on the Type 1098 or 1098H actuator
can be lubricated annually, using the grease tting
(key 28, Figure 14). Stem O-rings can be checked
14
Types 1098-EGR and 1098H-EGR
for damage during normal operation by line pressure
leakage or unexpected grease extrusion from the
actuator vent (key 27, Figure 14). 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 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.

to 40-inch-pounds.
4. Check indicator zeroing by unscrewing the
indicator protector (key 19) and seeing if the
ange of the indicator nut (key 22) lines up evenly
with the bottom marking on the indicator scale
(key 18). If not, remove the indicator scale
and separate the indicator nut and hex nut
(key 8). Hold the indicator scale against the
indicator tting (key 5) with the scale base
resting against the shoulder of the tting, and turn
the indicator nut until its ange is aligned with
the bottom scale marking. Then lock both nuts
against each other, and install the indicator scale
and protector.
Replacing Trim Parts
Perform this procedure when inspecting, cleaning, or
replacing individual trim package parts. Key numbers
are referenced in Figures 12 and 13.
Note
O-ring, travel indicator parts, or
optional travel stop (key 32) in step 1
can be gained without removing the
1. Remove the indicator tting (key 5) and attached
parts. Proceed to step 5 if only maintenance on
the tting or attached parts is performed.
2. Remove the cap screws (key 3) on a cast iron
body or remove the hex nuts (key 29, not shown)
on a steel body, and pry the body ange loose
from the valve body (key 1).
3. Use the valve body as a holding xture if desired.
Flip the body ange over, and anchor it on the
valve body as shown in Figure 10, removing the
pipe plug (key 31) rst if necessary.
4. To gain access to the port seal (key 12), upper seal
(key 15), or valve plug part, unscrew the seat ring
(key 13) from the cage (key 11) and the cage from
the body ange. For leverage, a wrench handle
or similar tool may be inserted into the seat
ring slots (Figure 10) and a strap wrench may be
wrapped around a standard or a Whisper TrimTM
cage, or a soft bar may be inserted through the
windows of a standard cage. To remove the piston
ring (key 14) and/or plug O-ring (key 20), remove
the valve plug (key 16) from the body ange, insert
a screwdriver into the precut fold over area of
the piston ring, and unfold the piston ring. Proceed
to step 6 if no further maintenance is necessary.
5. To replace the body ange or gain access to the
spring, indicator stem (key 10), stem O-ring
(key 7), spring seat (key 28), E-ring (key 23),
or optional travel stop, remove the indicator
protector (key 19) and indicator scale (key 18).
Since some compression is left in the spring,
carefully remove the anged nut (key 22) and hex
nut (key 8). A screwdriver may be inserted
through the press-t bushing (key 6) to remove the
stem O-ring without removing the bushing. If
necessary, unscrew the travel stop (if used), and
unclip the E-ring from the indicator stem.
6. Replace and lubricate parts such as the gasket
(key 4) and cage O-ring (key 17) as necessary,
making sure that if the port and upper seals were
removed they are installed in their retaining slots
with the grooved sides facing out. Also lubricate
16
Types 1098-EGR and 1098H-EGR
any other surfaces as necessary for ease of
installation. No further main valve maintenance
is necessary if just the indicator tting and
attached parts were removed.
7. Install the plug O-ring (key 20) and piston ring
(key 14) onto the valve plug. Insert the valve
plug into the body ange, install the cage plus
upper seal and O-ring into the body ange and
then install the seat ring plus port seal into the
cage. Apply a thin coating of lubricant to seals
for protection during assembly. Use the valve
body as a holding xture during this step as
shown in Figure 10, and insert a wrench handle
(or similar tool) into the seat ring slots for
leverage when tightening the seat ring and cage.
8. Remove the upside-down body ange if it was
anchored on the body. Coat the cage seating
surfaces of the valve body web and the body
ange seating surfaces of the valve body neck
with a good grade of general-purpose grease.
Install the body ange on the body, and secure
it evenly with the cap screws or stud bolt nuts.
Except on the 1-inch (DN 25) body, which does
not use it, the pipe plug (key 31) must be
installed in the side tapping of the ange for
proper operation.
9. Make sure that the ange and stem O-rings
and the bushings are installed in the indicator
tting. Orient the spring seat as shown in
Figure 12, and attach it with the E-ring to the
slotted end of the indicator stem. Install the
travel stop (if used) on the spring seat, and then
install the spring.
10. Being careful not to cut the stem O-ring with
the stem threads, install the indicator tting down
over the indicator stem until resting on the
spring. Install the hex nut and then the anged
indicator nut on the indicator stem, pushing on
the tting if necessary to provide sufcient stem
thread exposure. To maintain clearance for
indicator part installation, draw up the spring
seat by turning the hex nut down on the stem
until the threads bottom.
11. Install the indicator tting with attached parts
into the body ange. Back the hex nut off
until the spring completely closes the valve plug
against the port and upper seals, as indicated
by stem threads showing between this nut and
the tting. Hold the indicator scale against the
tting with the scale base resting against the
shoulder of the tting, and turn the indicator
nut until its ange is aligned with the bottom
scale marking. Then lock both nuts against each
other, and install the indicator scale and protector.

Remove the following (as shown in Figure 15): lter
body (key 1), machine screw (key 4), gasket (key 7),
two at washers (key 5), and lter element (key 2).
Upon reassembly, one of the at washers must go
between the lter element and lter head (key 3) and
the other must go between the lter element and
gasket. Use a good grade of pipe thread sealant on
the lter head pipe threads.
