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 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 satised, 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 orice (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 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 psi / 1.7 bar or when using the 61 Series or Y600AM pilots.



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 specically for the red main valve spring selection in the NPS 6 / 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.

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.

Note

Normal pressure drop assists shutoff. Therefore, leakage may result during any reverse pressure drop condition.

1. Use qualied 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. 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.

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 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 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.

5. 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.

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.

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.

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 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.

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

Boiler Fuel Pressure Control

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 conguration:

• 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 5 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.

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 6). 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 signicantly increases the stroking speed of the Type 1098-EGR. See Figure 6 for schematic.

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 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 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. 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.

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

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.

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 was 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.

5. Slowly open the downstream block valve.

6. Slowly close the bypass valve, if any.

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 two 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.

Wide-Open Monitor (Figure 8)

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.

Regardless of which regulator is used as the monitor,

it should be equipped with a pilot supply regulator set

to limit the pilot supply pressure to 10 to 15 psig / 0.69 to 1.0 bar above control pressure. Since the pilot on

the monitoring regulator is wide open during normal

operation, the pilot supply regulator prevents differential relief valve chatter on the monitoring regulator pilot.

Installation

1. For both the wide-open monitoring regulator and the working regulator, perform the Standard SinglePilot 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.

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.

P1508

4. Slowly open the upstream pipeline vent valve. Allow all pressure to bleed out of both the piping and the pilot.

Working Monitor

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

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 dualpilot 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.

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 14) on the Type 1098

or 1098H actuator can be lubricated during regularly

scheduled maintenance, using the grease  tting (key 28, Figure 14). 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 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

Page 15

Types 1098-EGR and 1098H-EGR

(key 13, Figure 14) 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.

Replacing Quick-Change Trim Package

Perform this procedure if the entire trim package is replaced. Key numbers for both the complete main valve and its trim package are referenced in

Figures 12 and 13. Some replacement trim package assembly numbers are listed in a table in the parts list.

Note

All disassembly, trim change and reassembly steps in this section may be performed with the regulator in the main line and without disconnecting the pilot supply or control lines.

1. Remove the cap screws (key 3) with a cast iron body or remove the hex nuts (key 29, not shown) with a steel body. Pry the body ange (key 2) from the valve body (key 1) and lift out the trim package.

2. Perform any required inspection, cleaning or

maintenance on the exposed surfaces of the valve

body (key 1) or trim package. Replace the gasket (key 4) or cage O-ring (key 17) as necessary.

3. On a pre-built replacement trim package, 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.

4. To gain access to the port seal (key 12), upper seal (key 15) or valve plug (key 16) part, unscrew the

seat ring (key 13) from the cage (key 11) and the

cage from the body ange (key 2). 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 Trim™ 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 (key 2) or gain access to the spring (key 9), indicator stem (key 10), stem O-ring (key 7), spring seat (key 28), E-ring (key 23) or optional travel stop (key 32), 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 (key 12) and upper seals (key 15) were removed they are installed in their retaining slots with the grooved sides

facing out. Also lubricate any other surfaces as necessary for ease of installation. No further main

valve maintenance is necessary if just the

indicator tting (key 5) and attached parts were removed.

7. Install the plug O-ring (key 20) and piston ring (key 14) onto the valve plug (key 16). Insert the valve plug into the body ange (key 2), install the

Type 95H Supply Pressure Regulator

This section includes instructions for disassembly and

assembly of replacement parts. All key numbers refer to Figure 23.

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 orice (key 3). If damaged, unscrew the orice 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.

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.
