Type 99 Pressure Reducing Regulator
!
WARNING
Since a pilot-operated regulator is
constructed of both a pilot and a main
valve, care should be used not to exceed
the maximum inlet pressure shown on
the nameplate of either unit. When inlet
pressure exceeds the pilot limitation, a
pilot supply reducing regulator and/or
relief valve is required.

Description
The Type 99 gas regulator provides a broad capacity
for controlled pressure ranges and capacities
in a wide variety of distribution, industrial and
commercial applications.
A Type 99 regulator has a Type 61L, 61LE or 61LD (low
pressure); Type 61H (high pressure); or Type 61HP
(extra high pressure) pilot integrally mounted to the
actuator casing as shown in Figure 1. The Type 99
regulator can handle up to 1000 psig / 69.0 bar inlet
2
pressure (the 1000 psig / 69.0 bar regulator requires a
Type 1301F pilot supply regulator and a Type H110
pop relief valve). The pilot supply regulator reduces
inlet pressure to a usable 200 psig / 14 bar for the
extra high-pressure pilot. The standard Type 99
regulator comes with O-ring seals on the guide
bushing and valve carrier to keep main valve body
outlet pressure from interfering with outlet pressure in
the lower casing assembly.

Figure 2. Schematic of Type 99 Regulator with Type 61L (Low Pressure) Pilot
Principle of Operation
The key to the operation of a Type 99 regulator is the
yoked double-diaphragm pilot. Fast response and
accuracy are made possible by the amplifying effect
of the pressure-balanced pilot and by the two-path
control system. The function of the pilot is to sense
change in the controlled pressure and amplify it into a
larger change in the loading pressure. Any changes
in outlet pressure act quickly on both the actuator
diaphragm and the loading pilot, thus providing the
precise pressure control that is a characteristic of a
two-path system.
A typical pilot has an approximate gain of 20, which
means the outlet pressure needs to droop only 1/20
as much as a direct-operated regulator in order to
obtain the same pressure differences across the main
diaphragm. Advantages of a pilot-operated regulator are
high accuracy and high capacity.
Upstream or inlet pressure is utilized as the operating
medium, which is reduced through pilot operation to
load the main diaphragm chamber. Tubing connects
the inlet pressure to the pilot through a filter assembly.
Downstream or outlet pressure registers underneath the
main diaphragm through the downstream control line.
In operation, assume the outlet pressure is less than
the setting of the pilot control spring. The top side of the
pilot diaphragm assembly will have a lower pressure
than the setting of the spring. Spring forces the
diaphragm head assembly upward, opening the relay
or inlet orifice. Additional loading pressure is supplied to
the pilot body and to the top side of the
main diaphragm.
This creates a higher pressure on the top side of the
main diaphragm than on the bottom side, forcing the
diaphragm downward. This motion is transmitted
through a lever, which pulls the valve disk open,
allowing more gas to flow through the valve.
When the gas demand in the downstream system
has been satisfied, the outlet pressure increases.
The increased pressure is transmitted through the
downstream control line and acts on top of the pilot
diaphragm head assembly. This pressure exceeds
the pilot spring setting and forces the head assembly
down, closing the orifice. The loading pressure acting
on the main diaphragm bleeds to the downstream
system through a small slot between the pilot bleed
valve and the bleed orifice.

2. Maximum inlet rating is equivalent to the 7/8 in. / 22 mm orifice.
Normally, excess loading pressure slowly escapes
downstream around the bleed valve (Figure 2)
or through the relief valve body (Figure 3). Since
loading pressure needs to exceed outlet pressure
only moderately to stroke the main valve fully open,
a continued increase in loading pressure differential
extends the main diaphragm and the pusher post
assembly far enough to separate the bleed valve and
the bleed orifice. This action permits quick dumping of
excess loading pressure into the downstream system.
The pilot valve diaphragm acts as a sealing member
for the loading chamber and as a balancing member
to the upper pilot diaphragm. These two diaphragms
are connected by a yoke so any pressure change in
the pilot chamber has little effect on the position of the
pilot valve. Therefore, the active diaphragm in the pilot
is the upper pilot diaphragm and the pressure on the
top side of this diaphragm opposes the force of the
pilot control spring.
With a decrease in loading pressure on top of the main
diaphragm, the main spring exerts an upward force on
the diaphragm rod connected to the main diaphragm,
pulling it in an upward direction. This moves the main
valve towards the seat, decreasing the flow to the
downstream system.
Monitoring Systems

Monitoring regulators serve as overpressure protection
devices to limit system pressure in the event of an
open failure of a working regulator feeding the system.
Two methods of using Type 99 regulators in monitoring
applications are:

Working Monitor
On a working monitor installation (Figure 4), the
control line of the monitoring pilot is connected
downstream of the working regulator. During
normal operation, distribution pressure causes
the monitoring pilot to stand wide open. Full pilot
supply pressure enters the working monitor pilot and
permits the working monitor regulator to control at its
intermediate pressure setting.
Open failure of the working regulator increases
distribution pressure as the working regulator goes
wide open. Intermediate pressure is then ignored by
the monitoring regulator, which controls downstream
pressure at its own pressure setting (slightly higher
than the normal control pressure).
The monitoring pilot should be upstream of the working
monitor regulator. This enables a closer setpoint
between the working regulator and the monitoring
pilot. Special Types 161AYW and 627-109 monitoring
pilots with quick-bleed operation have been designed
to give faster response to abnormal downstream
conditions. Table 5 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 open.
Wide-Open Monitor
The control line of the upstream regulator is
connected downstream of the second regulator
(Figure 5), so that 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.
The upstream regulator must have an O-ring seal
on the valve carrier assembly. This seals off the leak
path that otherwise would let line pressure ahead of
the working regulator inlet try to close the wide-open
monitoring regulator.
Installation
!
WARNING
Personal injury, equipment damage or
leakage due to escaping gas or bursting
of pressure containing parts might result
if this regulator is overpressured or is
installed where service conditions could
exceed the limits for which the regulator
was designed 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 (as required
by the appropriate code, regulation or
standard) to prevent service conditions
from exceeding those limits.
A regulator may vent some gas to
the atmosphere in hazardous or
flammable gas service, vented gas might
accumulate and cause personal injury,
death or property damage due to fire or
explosion. Vent a regulator in hazardous
gas service to a remote, safe location
away from air intakes or any hazardous
location. The vent line or stack opening
must be protected against condensation
or clogging.

Type 99
Clean out all pipelines before installation and check
to be sure the regulator has not been damaged or
collected foreign material during shipping.
Apply pipe compound to the external pipe threads
only with a threaded body or use suitable line gaskets
and good bolting practices with a flanged body. This
regulator may be installed in any position desired as
long as the flow through the body is in the direction
indicated by the arrow on the body. Install a three-valve
bypass around the regulator if continuous operation is
necessary during maintenance or inspection.
Although the standard orientation of the actuator and
pilot to the main valve body is as shown in Figure 1, this
orientation may be changed as far as the inlet tubing
(key 24, Figure 9 or 17) will permit by loosening the
union nut (key 14, Figure 9), rotating the actuator lower
casing (key 29, Figure 9) as desired and tightening
the union nut. To keep the pilot spring case from being
plugged or the spring case from collecting moisture,
corrosive chemicals or other foreign material, the vent
must be pointed down, oriented to the lowest possible
point on the spring case or otherwise protected. Vent
orientation may be changed by rotating the spring case
with respect to the pilot body.
To remotely vent a low-pressure pilot, install the vent
line in place of the pressed-in vent assembly (key 60,
Figure 9). Install obstruction-free tubing or piping into
the 1/4 in. / 6.4 mm vent tapping. Provide protection
on a remote vent by installing a screened vent cap into
the remote end of the vent pipe.
To remotely vent a high-pressure pilot, remove the
threaded-in vent assembly (key 72, Figure 12)
from the high-pressure pilot spring case and install
obstruction-free tubing or piping into the 1/4 in. /
6.4 mm vent tapping. Provide protection on a remote
vent by installing a screened vent cap into the remote
end of the vent pipe.
An upstream pilot supply line is not required because
of the integral pilot supply tubing (key 24, Figure 9
or 17). However, as long as the 1/4 NPT tapping
in the main valve body is plugged, this tubing may
be disconnected from both the main valve and
filter assembly (key 75, Figures 9 and 16) in order
to install a pilot supply line from a desired remote
location into the filter.
If the maximum pilot inlet pressure will be exceeded
by main valve pressure, install a separate pressure
reducing regulator (if not already provided) in the pilot
supply line.

A Type 99 regulator has two 1/2 NPT control line
pressure taps on opposite sides of the lower casing
(key 29, Figure 9). The regulator normally comes from
the factory with the tap closest to the regulator outlet left
unplugged for the downstream control line as shown in
Figure 1 and with opposite tap plugged.
Attach the control line from the unplugged tap 2 to
3 ft / 0.61 to 0.91 meter downstream of the regulator
in a straight run of pipe. If impossible to comply with
this recommendation due to the pipe arrangement, it
may be better to make the control line tap nearer the
regulator outlet rather than downstream of a block
valve. Do not install the tap near any elbow, swage or
nipple which might cause turbulence.
In many instances, it will be necessary to enlarge the
downstream piping to keep flow velocities within good
engineering practices. Expand the piping as close to
the regulator outlet as possible.
!
WARNING
Adjustment of the pilot control spring to
produce an outlet pressure higher than
the upper limit of the outlet pressure
range for that particular spring can cause
personal injury or equipment damage
due to bursting of pressure-containing
parts. Dangerous accumulation of gases
may also cause bursting if the maximum
actuator emergency casing pressure in
the Specifications section is exceeded. If
the desired outlet pressure is not within
the range of the pilot control spring,
install a spring of the proper range
according to the Maintenance section.
Each regulator is factory-set for the pressure setting
specified on the order. If no setting was specified, outlet
pressure was factory-set at the midrange of the pilot
control spring. In all cases, check the control spring
setting to make sure it is correct for the application.
Overpressure Protection
The Type 99 regulator has an outlet pressure
rating lower than its inlet pressure rating. Complete
downstream overpressure protection is required if
the actual inlet pressure can exceed the regulator
outlet pressure rating or the pressure ratings of any
downstream equipment. Although the Type H110
relief valve provides sufficient relief capacity to protect
Type 99
the extra high-pressure pilot of 1000 psig / 69.0 bar
maximum inlet pressure in case the Type 1301F supply
regulator fails open, this protection is insufficient if the
main valve body fails open. Regulator operation within
ratings does not preclude the possibility of damage from
external sources or from debris in the lines. A regulator
should be inspected for damage periodically and after
any overpressure condition.
!
WARNING
The 1000 psig / 69.0 bar maximum
inlet regulator must not be used on
hazardous gas service unless the
Type H110 relief valve can be vented
into a safe area. If vented gas can
accumulate and become a hazard in
enclosed conditions such as in a pit,
underground or indoors, the relief valve
must be repiped to carry the gas to a
safe location.
A repiped vent line or stack must be
located to avoid venting gas near
buildings, air intakes or any hazardous
location. The line or stack opening must
be protected against condensation,
freezing and clogging.
The only adjustment on the regulator is the reduced
pressure setting affected by the pilot control spring
(key 43, Figure 9, 12, 14 or 18). Remove the closing
cap assembly (key 46, Figure 9, 14 or 15) and turn
the adjusting screw (key 45, Figure 9, 14, 15 or 18).
Turning the adjusting screw clockwise into the spring
case increases the controlled or reduced pressure
setting. Turning the adjusting screw counterclockwise
decreases the reduced pressure setting. Always
replace the closing cap after making adjustments.
Shutdown
Installation arrangements may vary, but in any
installation, it is important to open and close valves
slowly and the outlet pressure be vented before
venting inlet pressure to prevent damage caused by
reverse pressurization of the regulator.
1. Isolate the regulator from the system. Close the
upstream block valve to the pilot and regulator inlet.
2. Close the downstream block valve to the pilot
sense connection and the regulator outlet.
3. Vent the downstream pressure by slowly opening
the vent valve to vent all pressures.
4. Vent inlet pressure slowly through the vent valve to
release any remaining pressure in the regulator.
Startup
Maintenance
Key numbers are referenced in Figures 9 through 15
for a low or high-pressure pilot and in Figure 18 for an
extra high-pressure pilot.
Regulator parts are subject to normal wear and must be
inspected and replaced as necessary. The frequency
of inspection and replacement of parts depend on the
severity of service conditions or the requirements of
local, state and federal rules and regulations.
1. Very slowly open the upstream block valve.
2. Slowly open the hand valve (if used) in the control
line. The unit will control downstream pressure
at the pilot control spring setting. If changes in
the pressure setting are necessary, follow the
procedure in the Adjustment section.
3. Slowly open the downstream block valve.
4. Slowly close the bypass valve, if any.
5. Check all connections for leaks.
Adjustment
With proper installation completed, perform the
adjustment procedure while using pressure gauges to
monitor pressure.
!
WARNING
Avoid personal injury or damage to
property from sudden release of pressure
or uncontrolled gas or other process fluid.
Before starting to disassemble, isolate
the pilot or regulator from all pressure
and cautiously release trapped pressure
from the pilot or regulator. Use gauges to
monitor inlet, loading and outlet pressures
while releasing these pressures.
9
Type 99
On reassembly of the regulator, it is recommended
that a pipe thread sealant be applied to pressure
connections and fittings as indicated in Figures 7
and 9 and lubricant be applied to sliding and bearing
surfaces as indicated in Figures 7 and 9, and that an
anti-seize compound be applied to adjusting screw
threads and other areas indicated in Figures 9 and 11.
Actuator and Standard P590 Series Filter
This procedure is to be performed if changing the main
spring and spring seat for those of a different range,
or if inspecting, cleaning or replacing any other parts.
Unless otherwise indicated, part key numbers for a
Type 99 regulator with low or high-pressure pilot and
disk or O-ring seat are referenced in Figures 9 through
15, part key numbers unique to the 1000 psig / 69.0 bar
maximum inlet regulator are referenced in Figure 17 and
part key numbers for a Type 61HP (extra high pressure)
pilot are referenced in Figure 18.
1. Access to all internal actuator parts can be gained
without removing the main valve body from the
line. Disconnect the loading tubing from the
upper casing.
CAUTION
If the regulator has an indicator
assembly, perform the following step
carefully to avoid bending the travel
indicator stem (key 103, Figure 6).
Note
The O-rings and gaskets (keys 111 and
108, Figure 6) in the indicator assembly
are static seals and need not be
disturbed, unless they are leaking.
2. R
emove the four cap screws (key 58, Figure 9) and
lift off the spring case (key 1). Remove the travel
indicator stem, if any, by unscrewing the indicator
stem adaptor (key 101, Figure 6).
3. Remove the main spring seat (key 2, Figure 9)
and main spring (key 3).
4. Remove the 12 cap screws (key 12, Figure 9)
and hex nuts (key 13), and lift off the upper casing.
5. Remove the diaphragm (key 11, Figure 9) and
diaphragm plate (key 10) by tipping it so that the
lever (key 9) slips out of the pusher post (key 8).
6. S
eparate the diaphragm (key 11, Figure 9) and
diaphragm plate (key 10) by unscrewing the
diaphragm rod (key 4) from the pusher post (key 8).
10
Inspect the diaphragm (key 11) and pusher post
gasket (key 7). Either part must be replaced if it is
damaged or no longer pliable.
7. If the unit has a stem seal O-ring (key 64, Figure 7
or 17), this O-ring may be replaced by removing the
retaining ring or cotter pin (key 28, Figure 9) and
disconnecting the lever (key 9) from the valve carrier
(key 26, Figure 9 or 17), removing the union nut
(key 14, Figure 9), disconnecting the pilot supply
tubing (key 24, Figure 9 or 17), and sliding the lower
casing (key 29) away from the valve body (key 17,
Figure 9), with a disk or O-ring seat, the valve carrier
must be pulled out of the lower casing (key 29,
Figure 9 or 17) to gain access to the O-ring. Another
O-ring, held captive by the pressed-in bushing, is part
of the lower casing assembly on a stem seal unit and
normally does not require replacement.
8. If clogging is suspected in the upstream regulator
passages, disconnect the pilot supply tubing
(key 24, Figure 9 or 17), remove the filter assembly
(key 75, Figure 9), and blow through it to check for
filter clogging. If necessary, to clean or replace filter
parts in a standard P590 Series filter assembly,
remove the following as shown in Figure 16:
filter body (key 1), machine screw (key 4), spring
washer (key 6), gasket (key 7), washers (key 5)
and filter element (key 2). Upon reassembly, one
of the two washers (key 5) must go between the
filter element (key 2) and filter head (key 3) and the
other must go between the filter element (key 2)
and gasket (key 7).
9. If the lower casing (key 29, Figure 9) was
removed, install a new body gasket (key 16)
and, with a disk or O-ring seat, slide the valve
carrier (key 26) into the casing (key 29). Then
slide the entire assembly into the valve body
(disk or O-ring seat) and secure with the union
nut (key 14). Secure the lever (key 9) to the valve
carrier (key 26) with the retaining ring or cotter
pin (key 28).
10. Loosely reassemble the diaphragm (key 11,
Figure 9) and diaphragm plate (key 10) so that
the bolt holes (key 11) and loading connection
hole in the diaphragm can be properly aligned
with the corresponding holes in the lower casing
(key 29) when the lever (key 9) is fitted properly
into the pusher post assembly (key 8). When this
orientation is made, install the collar (key 6) and
tighten the diaphragm rod (key 4) into the pusher
post (key 8).
11. In order for the regulator to operate properly, the
assembled collar (key 6), diaphragm (key 11),
Type 99
diaphragm plate (key 10), pusher post assembly
(key 8) and diaphragm rod (key 4) must be mounted
on the ball of the lever (key 9) so that the pusher
post (key 8) orientation is as shown in Figure 9.
12. Install the upper casing (key 56, Figure 9) and
secure it to the lower casing (key 29) with the twelve
cap screws (key 12) torque 580 to 920 in-lbs /
65.5 to 104 N•m and hex nuts (key 13). Put lower
casing (key 29) back on body and install union nut
(key 14).
CAUTION
To avoid part damage due to over
compressing the main spring seat (key 2),
always use main spring seat 1E242724092
with main spring 0W019127022.
13. Thread the main spring seat (key 2) to the bottom
of the diaphragm rod (key 4) threads and then
back out 1 revolution.
14. Install a new spring case gasket (key 57, Figure 9),
the spring case (key 1) and the four cap screws
(key 58) with 340 to 420 in-lbs / 38.4 to 47.5 N•m
of torque, making sure the indicator stem, O-ring
and gaskets (keys 103, 111 and 108, Figure 6) are
installed, if used.
15. C
onnect the loading tubing, then refer to
the Startup section for putting the regulator
into operation.
Type 61L, 61LD, 61LE (Low) or 61H
(High Pressure) Pilot
This procedure is to be performed if changing the
control spring for one of a different range or if inspecting,
cleaning or replacing any other pilot parts. Key numbers
are referenced in Figure 9 through 15.
1. Remove the closing cap (key 46), if used, and
unscrew the adjusting screw (key 45) to relieve
control spring compression.
2. Disconnect the loading tubing (key 53) and pilot
supply tubing (key 24).
3. U
nscrew the eight cap screws (key 47) and remove
the pilot assembly from the lower casing (key 29).
4. Use the projecting prong in the relay valve body
(key 39) as the restraining member and remove
the diaphragm nuts (key 13, Figure 9 and key 51,
Figure 11). Separate the parts and inspect the
diaphragms (keys 30 and 40) and O-ring seal
(key 33). Replace if worn or damaged.
5. Unscrew the bleed orifice (key 52, Figure 11)
from the yoke (key 37). Also to be removed with
the bleed orifice are the relay disk assembly
(key 48) and bleed valve (key 50). These parts can
be unthreaded for inspection and replacement,
if necessary.
6. When reassembling the pilot, the relay disk holder
assembly (key 48, Figure 11) and both diaphragms
(key 30, Figure 11 and key 40, Figure 12) should
be tightened on the yoke (key 37) after it is placed
in the body.
Note
Before putting the relay spring case over
the diaphragm, make certain the yoke is
square with respect to the prong in the
relay body. (The yoke can bind on the
prong if it is not square.)
7. Use care in reassembly to be sure the edges of
the diaphragms (key 30, Figure 11 and key 40,
Figure 12) slip properly into the recess on the
lower casing (key 29, Figure 9) and relay valve
body (key 39). With the pilot in place, check to
see if it can be rocked. If it does not rock, it is in
place and the diaphragms (key 30, Figure 11 and
key 40, Figure 12) are free of wrinkles. With both
diaphragms firmly in place, install the cap screws
(key 47, Figure 9) using torque 150 in-lbs / 16.9 N•m
of torque. Tighten using a crisscross pattern to
avoid placing a strain on the unit. Set the pilot
control spring (key 43) according to the adjustment
information in the Startup section.
8. Reinstall the closing cap (key 46, if used). If you
have a plastic closing cap, be sure that you have a
vent (key 60) in place of the pipe plug installed in
the low-pressure pilot spring case (key 44).
Type 61HP (Extra High Pressure) Pilot
This procedure is to be performed if changing the
control spring for one of a different range, or if
inspecting, cleaning or replacing any other pilot parts.
Key numbers are referenced in Figure 18 unless
otherwise specified.
1. Unscrew the adjusting screw (key 45) to relieve
control spring compression.
2. Disconnect the loading tubing (key 53, Figures 9
and 18) and pilot supply tubing (key 24, Figure 9).
3. Remove the six cap screws (key 123) which fasten
the spring case (key 44), spring seat (key 68) and
control spring (key 43) to the pilot body (key 39).
11
Type 99
4. Unscrew the diaphragm nut (key 128) and remove
a diaphragm plate (key 41A), diaphragm (key 40)
and another diaphragm plate (key 41B).
5. Unscrew the eight cap screws (key 47) and
remove the pilot body (key 39) and gasket
(key 126). Remove six cap screws (key 35), seal
washers and the flange adaptor (key 125).
6. Unscrew the relief valve body (key 119) and remove
a diaphragm plate (key 41C), diaphragm (key 30)
and another diaphragm plate (key 41D). Inspect the
diaphragm inserts (key 150) and both diaphragms
(keys 30 and 40). Replace if worn or damaged.
7. The relief valve assembly can be further
disassembled for inspection by unscrewing the
relief valve cap (key 118).
8. Four machine screws (key 130) hold both yoke
caps (keys 37 and 116) to the yoke legs (key 31).
Separate these parts to expose the pilot valve.
9. Unscrew the inlet orifice (key 38) to inspect its
seat, the inlet valve plug (key 117) and valve spring
(key 124).
Note
Make certain that the yoke assembly is
square with respect to the cross member
of the body casting so that it will not
bind on the body.
Converting the Pilot
Note
A complete pilot assembly rather than
individual parts may be ordered for
the following conversion procedure.
When a low-pressure pilot is ordered
for field conversion of a high-pressure
pilot or vice versa, the replacement pilot
assembly comes complete with a pilot
cover (key 132, Figure 9). Remove this
cover before installing the replacement
pilot on the existing regulator. The cover
can then be installed on the removed
pilot to form a complete Type 61 (low or
high pressure) pilot for use elsewhere.
When changing one pilot construction (low pressure, high
pressure or extra high pressure) for another, all parts
attached to the lower casing (key 29, Figure 9) may need
to be replaced with those appropriate for the desired
construction. At the very least, when changing from a
low to high-pressure pilot or vice versa, everything below
the lower pilot diaphragm (key 40, Figure 9) except the
cap screws and the hex nut (keys 47 and 13, Figure 9)
will need to be replaced. Actuator and main valve parts
may remain unchanged unless a change in service
conditions requires a change in seat construction, main
spring or main spring seat. See the Parts List sections
for obtaining the appropriate conversion parts.
10. W
hen reassembling, screw in the inlet orifice
(key 38) all the way and secure the yoke caps
(keys 37 and 116) to the yoke legs (key 31).
Replace two diaphragm plates (keys 41B and 41D),
the diaphragms (keys 30 and 40) and inserts, two
more diaphragm plates (keys 41A and 41C), the
diaphragm nut (key 128) and the relief
valve assembly.
Main Valve Trim with Disk or O-ring Seat
11. Assemble the control spring (key 43) and spring
seat (key 68) into the body and spring case (key 44),
being careful that the diaphragms (keys 30 and 40)
are free of wrinkles and properly in place, and
evenly installing the cap screws (key 123) in a
crisscross pattern to avoid placing a strain on the
unit. Install the body flange adaptor (key 125) with
seal washers (key 126) and cap screws (key 47).
Install a new gasket and secure the pilot to the lower
casing (key 29) with eight cap screws (key 47).
Set the control spring (key 43) according to the
adjustment information in the Startup section.
Note
12
This procedure is to be performed if inspecting, cleaning
or replacing trim parts. Part key numbers for a Type 99
regulator with disk or O-ring seat are referenced in
Figures 9 and 10 and part key numbers for the disk
seat unique to the 1000 psig / 69.0 bar maximum inlet
regulator are referenced in Figure 17.
All trim maintenance may be performed
with the valve body (key 17, Figure 9
or 17) in the line and with the elbow
(key 23), pilot supply tubing (key 24) and
pilot supply regulator (if used) attached
to the valve body unless the valve body
itself will be replaced.
1. Disconnect the pilot supply tubing (key 24) and
downstream control line.

screw (key 22) or disk and holder assembly
(key 18, Figure 17) on disassembly or reassembly.
A thin-walled socket may be used to remove
the orifice.
3. Access to the disk or O-ring (key 19, Figure 9) can
be gained by removing the cap screw (key 22) and
retainer (key 21), while on the 1000 psig / 69.0 bar
maximum inlet regulator the entire disk and holder
assembly (key 18, Figure 17) is removed as a unit.
If necessary, the holder (key 18, Figure 9 or 17) or
adaptor (key 157, Figure 17) can be removed by
taking out the cotter pin (key 25, Figure 9 or 17).
4. Install a new body gasket (key 16, Figure 9) and
a new disk, O-ring or disk and holder assembly as
necessary. Then slide the entire assembly into
the valve body (key 17) and secure with the union
nut (key 14).
5. Connect the pilot supply tubing (key 24) and
downstream control line, then refer to the Startup
section for putting the regulator into operation.
Parts Ordering
A serial number is assigned to each regulator, and it
is stamped on both the actuator and pilot nameplates.
If the pilot is replaced, the new pilot will have its own
serial number different from the main valve serial
number. Always indicate one or both serial numbers
when communicating with your local Sales Office.
When ordering a replacement part, be sure to include
the complete eleven-character part number.
