Type 99 Pressure Reducing Regulators
Introduction
Scope of the Manual
This manual describes and provides instructions and
parts lists for Type 99 pressure reducing regulators
complete with standard P590 Series integral lter.
However, complete instructions and parts listing for the
Type 1301F pilot supply regulator, and other Fisher®
equipment, such as monitoring pilots will be found in
separate instruction manuals.
Description
The Type 99 gas regulators provide a broad capacity
for controlled pressure ranges and capacities
in a wide variety of distribution, industrial, and
commercial applications.
Type 99
A Type 99 regulator has a Type 61L (low pressure),
Type 61H (high pressure), or a 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 pressures
(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 (13,8 bar) for the extra
high pressure pilot. This regulator comes standard with
O-ring seals on the guide bushing and valve carrier
(key 26, Figure 7) to keep main valve body outlet
pressure from interfering with outlet pressure in the
lower casing assembly (key 29, Figure 9).
Specications
WARNING
!
Since a pilot-operated regulator is
constructed of both a pilot and a main
valve, care should be used not to exceed
W2676
Figure 1. Type 99 Regulator with Type 61H (high pressure) Pilot
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 will be required.
Specications and ratings for various Type 99
constructions are listed in the Specications section
on page 2. Some specications for a given regulator
as it originally comes from the factory are stamped
on nameplates located on the pilot and actuator
spring cases. A tag (key 159, Parts List) additionally
may be installed on the pilot to indicate a regulator
with O-ring stem seal. These regulators and their
installations should be checked for compliance with
applicable codes.

Principle of Operation
The key to the operation of a Type 99 regulator is the
yoked double-diaphragm pilot (letter keys in this section
refer to both Figures 2 and 3 unless otherwise noted).
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 characteristic of a
two-path system.

OUTLET PIPE
INLET
In operation, assume the outlet pressure is less
than the setting of pilot control spring (A). The top
side of pilot diaphragm assembly (F) will have a
lower pressure than the setting of spring (A). Spring
(A) forces the diaphragm head assembly upward,
opening the relay or inlet orice (C). Additional loading
pressure is supplied to the pilot body and to the top
side of main diaphragm (E).
This creates a higher pressure on the top side of the
main diaphragm (E) 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.
A typical pilot has an approximate gain of 20, which
means the outlet pressure needs to droop only 1/20 as
much as a self-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 (E) through the downstream control line.
When the gas demand in the downstream system
has been satised, the outlet pressure increases.
The increased pressure is transmitted through the
downstream control line and acts on top of the
pilot diaphragm head assembly (F). This pressure
exceeds the pilot spring setting and forces the head
assembly down, closing orice (C). The loading
pressure acting on the main diaphragm (E) bleeds to
the downstream system through a small slot between
the pilot bleed valve (D) and the bleed orice (H).
Normally, excess loading pressure slowly escapes
downstream around bleed valve (D) (Figure 3) or

through the relief valve body (J) (Figure 4). 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 (E) and the pusher
post assembly (K) far enough to separate the bleed
valve (D) and the bleed orice (H). This permits
quick dumping of excess loading pressure into the
downstream system.
With a decrease in loading pressure on top of the
main diaphragm (E), the main spring (B) exerts an
upward force on the diaphragm rod connected to the
main diaphragm (E), pulling it upward. This moves
the main valve toward its seat, decreasing ow to the
downstream system.
Diaphragm (G) in the pilot valve acts as a sealing
member for the loading chamber and as a balancing
member to diaphragm (F). 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
(F) and the pressure on the top side of this diaphragm
opposes the force of the pilot control spring (A).

Monitoring Systems
Monitoring regulators serve as overpressure protection
devices to limit system pressure in the event of open
failure of a working regulator feeding the system. Two
methods of using Type 99 regulators in monitoring
systems are as follows:
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 4 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.

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

relief valve provides sufcient relief capacity to protect
the extra high pressure pilot of the 1000 psig (69,0 bar)

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 male pipe threads only with
a screwed 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 11) 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, or on the extra
high pressure pilot with optional tapped spring case by
rotating the vent with respect to the spring case.
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

the screwed-in vent assembly (key 72, Figure 9) from
the high pressure pilot spring case or the pressed-in
vent assembly from the extra high pressure pilot
spring case and install obstruction-free tubing or piping
into the 1/4-inch (6,35 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 11). However, as long as the 1/4-inch NPT
tapping in the main valve body is plugged, this
tubing may be disconnected from both the main
valve and lter assembly (key 75, Figure 9) 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 reducing
regulator (if not already provided) in the pilot supply line.
A Type 99 regulator has two 1/2-inch threaded 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 feet (0,61 to 0,91 meter) downstream of the regulator
in a straight run of pipe. If impossible to comply with
7
Page 8
Type 99
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 make 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 or the dangerous accumulation
of gases if the maximum actuator
emergency casing pressure in the
Specications 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.
The only adjustment on the regulator is the reduced
pressure setting affected by the pilot control spring
(key 43, Figure 9 or 11). Remove the closing cap
assembly (key 46, Figure 9) and turn the adjusting
screw (key 45, Figure 9 or 11). Turning the adjusting
screw clockwise into the spring case increases the
controlled or reduced pressure setting. Turning
the screw counterclockwise decreases the reduced
pressure setting. Always replace the closing cap, if
used, after making the adjustment.
Shutdown
Isolate the regulator from the system. Vent the
downstream pressure rst; then vent inlet pressure to
release any remaining pressure in the regulator.
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 on the
severity of service conditions or the requirements of
local, state, and federal rules and regulations.
WARNING
!
Each regulator is factory-set for the pressure setting
specied on the order. If no setting was specied, 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.
Startup
Key numbers are referenced in Figure 9 for a low or
high pressure pilot and in Figure 12 for an extra high
pressure pilot. With proper installation completed and
downstream equipment properly adjusted, perform the
following procedure while using pressure gauges to
monitor pressure.
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. See the
adjustment paragraph following these numbered
steps if changes in the setting are necessary during
the startup procedure.
3. Slowly open the downstream block valve.
4. Slowly close the bypass valve, if any.
5. Check all connections for leaks.
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.
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 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
8
Page 9
Type 99
disk or O-ring seat are referenced in Figure 9, part key
numbers unique to the 1000 psig (69,0 bar) maximum
inlet regulator are referenced in Figure 11, and part
key numbers for a Type 61HP (extra high pressure)
pilot is referenced in Figure 12.
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, Figure 9). Remove
the travel indicator stem, if any, by unscrewing the
indicator stem adapter (key 101, Figure 6).
3. Remove the main spring seat (key 2, Figure 9)
and main spring (key 3, Figure 9).
4. Remove the 12 cap screws (key 12, Figure 9)
and hex nuts (key 13, Figure 9), and lift off the
upper casing.
5. Remove the diaphragm (key 11, Figure 9) and
diaphragm plate (key 10, Figure 9) by tipping it so
that the lever (key 9, Figure 9) slips out of the
pusher post (key 8, Figure 9).
6. Separate the diaphragm and diaphragm plate by
unscrewing the diaphragm rod (key 4, Figure 9)
from the pusher post. Inspect the diaphragm
(key 11, Figure 9) and pusher post gasket (key 7,
Figure 9). 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 11), this O-ring may be replaced by
removing the retaining ring or cotter pin (key 28,
Figure 9) and disconnecting the lever from the
valve carrier (key 26, Figure 9 or 11), removing
the union nut (key 14, Figure 9 or 11),
disconnecting the pilot supply tubing (key 24,
Figure 9 or 11), and sliding the lower casing
(key 29, Figure 9) 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 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 11), 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 10: lter body (key 1), machine screw
(key 4), spring washer (key 6), gasket (key 7),
washer (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.
9. If the lower casing was removed, install a new body
gasket (key 16, Figure 9) and, with a disk or O-ring
seat, slide the valve carrier into the casing. Then
slide the entire assembly into the valve body (disk
or O-ring seat) and secure with the union nut.
Secure the lever to the valve carrier with the
retaining ring or cotter pin.
10. Loosely reassemble the diaphragm and
diaphragm plate so that the bolt holes and
loading connection hole in the diaphragm can
be properly aligned with the corresponding
holes in the casing when the lever is tted
properly into the pusher post. When this
orientation is made, install the collar (key 6,
Figure 9) and tighten the diaphragm rod into the
pusher post (key 8, Figure 9).
11. In order for the regulator to operate properly, the
assembled collar, diaphragm, diaphragm plate,
pusher post, and diaphragm rod must be
mounted on the ball of the lever so that the
pusher post (key 8, Figure 9) orientation is as
shown in Figure 9.
12. Install the upper casing and secure it to the
lower casing with the twelve cap screws torque
580 to 920 inch-pounds (65,5 to 104 N•m) and hex
nuts. Put lower casing back on body and install
union nut.

Page 10
Type 99
CAUTION
To avoid part damage due to over
compressing the main spring seat, always
use main spring seat 1E242724092 with
main spring 0W019127022.
13. Install the main spring and main spring seat,
turning the main spring seat until its bottom
shoulder is even with the bottom thread of the
diaphragm rod.
14. Install a new spring case gasket (key 57,
Figure 9), the spring case, and the four cap
screws with 340 to 420 inch-pounds (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) Pilots
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.
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 (keys 13 and 51). Separate
the parts and inspect the diaphragms (keys 30
and 40) and O-ring seal (key 33). Replace if worn
or damaged.
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 slip properly into the recess on
the lower casing and relay valve body. With the
pilot in place, check to see if it can be rocked. If
it does not rock, it is in place and the diaphragm
is free of wrinkles. With both diaphragms rmly
in place, install the cap screws using torque
150 inch-pounds (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.
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 12.
1. Unscrew the adjusting screw (key 45) to relieve
control spring compression.
2. Disconnect the loading tubing and pilot supply tubing.
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.
4. Unscrew the diaphragm nut (key 128) and remove
a diaphragm plate (key 41), diaphragm (key 40),
and another diaphragm plate.
5. Unscrew the eight cap screws and remove the
pilot body (key 39) and gasket. Remove six cap
screws, seal washers and the ange adapter.
5. Unscrew the bleed orice (key 52) from the yoke
(key 37). Also removed with the bleed orice are
the relay disk assembly (key 48) and bleed valve
(key 50). These parts can be unscrewed for
inspection and replacement, if necessary.
6. When reassembling the pilot, the relay disk holder
assembly and both diaphragms should be
tightened on the yoke after it is placed in the body.
10
6. Unscrew the relief valve body (key 119) and remove
a diaphragm plate, diaphragm, and another
diaphragm plate. Inspect the diaphragm inserts
(key 150) and both diaphragms. Replace if worn
or damaged.
7. The relief valve assembly can be further
disassembled for inspection by unscrewing the
relief valve cap (key 118).
Page 11
Type 99
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 orice (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 orice all
the way and secure the yoke caps to the yoke
legs. Replace two diaphragm plates, the
diaphragms, and inserts, two more diaphragm
plates, the hex nut, and the relief valve assembly.
11. Assemble the control spring and spring seat
into the body and spring case, being careful
that the diaphragms are free of wrinkles and
properly in place, and evenly installing the cap
screws in a crisscross pattern to avoid placing a
strain on the unit. Install the body ange adapter
with seal washers and cap screws. Install a new
gasket and secure the pilot to the lower casing
with eight cap screws. Set the control spring
according to the adjustment information in the
Startup section.
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 Figure 9, and part key numbers for
the disk seat unique to the 1000 psig (69,0 bar)
maximum inlet regulator are referenced in Figure 11.
Note
All trim maintenance may be performed
with the valve body (key 17, Figure 9
or 11) in the line and with the elbow
(key 23, Figure 9 or 11), pilot supply
tubing (key 24, Figure 9 or 11), and pilot
supply regulator (key 155, Figure 11, if
used) attached to the valve body unless
the valve body itself will be replaced.
1. Disconnect the pilot supply tubing and downstream
control line.
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 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
2. Loosen the union nut (key 14, Figure 9) and
remove the lower casing (key 29, Figure 9) with
the cap screw (key 22, Figure 9) or disk and
holder assembly (key 18, Figure 11) on
disassembly or reassembly. A thin-walled socket
may be used to remove the orice.
3. Access to the disk or O-ring (key 19, Figure 9) can
be gained by removing the cap screw and retainer
(key 21, Figure 9), while on the 1000 psig
(69,0 bar) maximum inlet regulator the entire
disk and holder assembly is removed as a unit.
If necessary, the holder (key 18, Figure 9 or 11) or
adapter (key 157, Figure 11) can be removed by
taking out the cotter pin (key 25, Figure 9 or 11).
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 and secure with the union nut.
5. Connect the pilot supply tubing and downstream
control line, then refer to the Startup section for
putting the regulator into operation.
