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.

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 lter 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 orice. 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 ow through the valve.
When the gas demand in the downstream system
has been satised, 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 orice. 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 orice.

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 orice. This action permits quick dumping of excess loading pressure into the downstream system.
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 ow to the downstream system.
6
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.
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
ammable gas service, vented gas might
accumulate and cause personal injury,
death or property damage due to re or
explosion. Vent a regulator in hazardous gas service to a remote, safe location away from air intakes or any hazardous location. The vent line or stack opening must be protected against condensation or clogging.
7
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 anged body. This
regulator may be installed in any position desired as
long as the ow 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 lter assembly (key 75, Figures 9 and 16)
in order to install a pilot supply line from a desired
remote location into the lter.
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 ow 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 Specications 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
specied on the order. If no setting was specied, 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 sufcient relief capacity to protect
8
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 insufcient 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.

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
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.
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.
Maintenance
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.
WARNING
!
Avoid personal injury or damage to property from sudden release of pressure
or uncontrolled gas or other process uid.
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 ttings 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. Remove 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. Separate the diaphragm (key 11, Figure 9) and
diaphragm plate (key 10) by unscrewing the
diaphragm rod (key 4) from the pusher post (key 8).
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 lter
assembly (key 75, Figure 9), and blow through it
to check for lter clogging. If necessary, to clean or replace lter parts in a standard P590 Series lter assembly, remove the following as shown in Figure 16: lter body (key 1), machine screw
(key 4), spring washer (key 6), gasket (key 7),
washers (key 5) and lter element (key 2). Upon
reassembly, one of the two washers (key 5) must
go between the lter element (key 2) and lter
head (key 3) and the other must go between the
lter 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 tted 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),
10
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. Connect 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.
5. Unscrew the bleed orice (key 52, Figure 11) from the yoke (key 37). Also to be removed with the bleed orice 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 rmly 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).
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. Unscrew 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.
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 specied.
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 ange 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 orice (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.
10. When reassembling, screw in the inlet orice
(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.
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 ange 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.
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 eld 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.
Main Valve Trim with Disk or O-ring Seat
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.
Note
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.

2. Loosen the union nut (key 14, Figure 9) and remove the lower casing (key 29) with the cap 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 orice.
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 Ofce.
When ordering a replacement part, be sure to include
the complete eleven-character part number.
