Principle of Operation
The pilot-operated Type FL (Figure 2) uses inlet
pressure as the operating medium, which is reduced
through pilot operation to load the actuator diaphragm.
Outlet pressure opposes loading pressure in the
actuator and also opposes the pilot control spring.
When outlet pressure drops below the setting of the
pilot control spring, pilot control spring force on the
pilot diaphragm opens the pilot valve plug, providing
additional loading pressure to the actuator diaphragm.
This diaphragm loading pressure opens the main valve
plug, supplying the required ow to the downstream
system. Any excess loading pressure on the actuator
diaphragm escapes downstream through the exhaust
restriction in the pilot.
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 the pilot diaphragm.
This pressure exceeds the pilot spring setting and moves
the diaphragm, closing the orice. The loading pressure
acting on the main diaphragm bleeds to the downstream
system through the exhaust restriction in the pilot.
Figure 2 also shows a Type FL regulator with a
Type PRX/131 pilot included. The Type PRX/131 pilot is
referred to as a quick dump or booster pilot as it helps
to boost the closing speed. When the Type PRX/131
pilot detects an increase in downstream pressure, it
allows the Type FL regulator to release pressure off the
downstream side of the diaphragm so it closes faster.
Type SA/2 Pilot Supply Filter Regulator
The PRX Series pilot are usually used together
with the Type SA/2 pilot supply lter regulator. The
Type SA/2 acts as a pressure stabilizer that provides a
constant supply pressure to the PRX Series pilot that
is approximately 45 psi / 3.1 bar over set pressure.
The Type SA/2 has an integral 5 micron lter. The
integral lter acts only as an emergency lter; gas
must be cleaned upstream of the regulator.

Monitoring Systems
Monitoring regulation is overpressure protection by
containment, therefore, there is no relief valve to vent
to the atmosphere. When the working regulator fails
to control the pressure, a monitor regulator installed
in series, sensing the downstream pressure, goes
into operation to maintain the downstream pressure
at a slightly higher than normal pressure. During an
overpressure situation, monitoring keeps the customer
on line. Also, testing is relatively easy and safe. To
perform a periodic test on a monitoring regulator,
increase the outlet set pressure of the working
regulator and watch the outlet pressure to determine if
the monitoring regulator takes over at the appropriate
outlet pressure.
Wide-Open Monitoring Systems (Figure 3)
There are two types of wide-open monitoring
systems: upstream and downstream. The difference
between upstream and downstream monitoring is
that the functions of the regulators are reversed.
Systems can be changed from upstream to
downstream monitoring and vice-versa, by simply
reversing the setpoints of the two regulators. The
decision to use either an upstream or downstream
monitoring system is largely a matter of personal
preference or company policy.
In normal operation of a wide-open conguration,
the working regulator controls the system’s outlet
pressure. With a higher outlet pressure setting, the
monitor regulator senses a pressure lower than its
setpoint and tries to increase outlet pressure by
going wide open. If the working regulator fails, the
monitoring regulator assumes control and holds the
outlet pressure at its outlet pressure setting.
Figure 3 shows a Type FL Wide-Open Monitor
conguration with a Type PRX/131 pilot included. The
Type PRX/131 pilot is referred to as a quick dump
or booster pilot as it helps to boost the pressure
release. The Type PRX/131 is tted to the monitor
regulator and allows the regulator to operate faster.
When the Type PRX/131 detects an increase in
downstream pressure, it allows the Type FL monitor
regulator to release pressure off the downstream
side of the diaphragm so it closes faster. The
Type PRX/131 pilot is always attached to the monitor
regulator in a Wide Open Monitor or Working Monitor
conguration. The Type PRX/131 should have a
setpoint about 5 to 10 psig / 0.34 to 0.69 bar above
the monitor pilot setpoint.
Working Monitoring Regulators (Figure 3)
In a working monitoring system, the upstream
regulator requires two pilots and it is always the
monitoring regulator. The additional pilot permits
the monitoring regulator to act as a series regulator
to control an intermediate pressure during normal
operation. In this way, both units are always operating
and can be easily checked for proper operation.
In normal operation, the working regulator controls
the outlet pressure of the system. The monitoring
regulator’s working pilot controls the intermediate
pressure and the monitoring pilot senses the system’s
outlet pressure. If the working regulator fails, the
monitoring pilot will sense the increase in outlet
pressure and take control.
Note
The working regulator must be rated
for the maximum allowable operating
pressure of the system because this will
be its inlet pressure if the monitoring
regulator fails. Also, the outlet pressure
rating of the monitoring pilot and any
other components that are exposed to
the intermediate pressure must be rated
for full inlet pressure.
Working monitor installations require a Type FL main
valve with a Type PRX/120 or PRX/120-AP working
pilot and a Type PRX/125 or PRX/125-AP monitoring
pilot for the upstream regulator and a Type FL with the
appropriate Type PRX/120 or PRX/120-AP pilot for the
downstream regulator.
Installation
!
WARNING
Personal injury or equipment damage,
due to bursting of pressure-containing
parts may result if this regulator is
overpressured or is installed where
service conditions could exceed the
limits given in the Specication section
and on the appropriate nameplate or
where conditions exceed any rating of the
adjacent piping or piping connections.
To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices to prevent service conditions
from exceeding those limits. Also, be
sure the installation is in compliance with
all applicable codes and regulations.

Additionally, physical damage to the
regulator could break the pilot off the
main valve, causing personal injury
and property damage due to bursting
of pressure-containing parts. To avoid
such injury and damage, install the
regulator in a safe location.
All Installations
A Type FL regulator bleeds no gas to atmosphere
during normal operation, making it suitable for
installation in pits and other enclosed locations
without elaborate venting systems. This regulator
also can 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.
1. Only personnel qualied through training and
experience should install, operate and maintain a
regulator. Before installation, make sure that there
is no damage to or debris in the regulator. Also,
make sure that all tubing and piping are clean
and unobstructed.
2. Install the regulator so that the ow arrow on the
main valve matches the ow direction of process
uid through the regulator. The Type FL may be
installed in any position, but it is normally installed
in a horizontal pipeline with the pilot or pilots
above the body.
3. Apply pipe compound to the external pipeline
threads before installing a regulator with threaded
NPT end connections. Use gaskets between
pipeline and regulator anges when installing a
regulator with anged end connections. When
installing butt weld end connections, remove
trim before welding and make sure to use
approved welding practices. Use approved piping
procedures when installing the regulator.
4. The optimal location of the sense and bleed lines
is between the Type FL and the Downstream block
valve. The tap location should be in a straight
section of pipe that is 8 to 10 pipe diameters
downstream of the outlet ange. These guidelines
are not mandatory but have been used to improve
stability at low ow conditions in some systems.
CAUTION
To prevent damage to the pilot during
Startup, the sense and bleed lines
should be located on the same side of
the downstream block valve.
5. Connect inlet supply pressure to the Type SA/2
1/4 NPT inlet, Port M.
!
WARNING
A regulator may vent some gas to the
atmosphere. In hazardous or ammable
gas service, vented gas may accumulate,
causing personal injury, death or
property damage due to bursting of
pressure-retaining parts. 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.
6. PRX Series pilots have a 1/4 NPT vent connection
in the spring case. To remotely vent gas from the
spring case, remove the screened vent and connect
1/4 in. / 6.4 mm piping or tubing to the spring case
connection. The piping or tubing should vent to a safe
location, have as few elbows as possible and have a
screened vent on its exhaust. Install the regulator and
any remote vent piping or tubing so that the vent is
protected from condensation, freezing or substances
that may clog it.
CAUTION
To avoid freeze-up because of pressure
drop and moisture in the gas, use anti-
freeze practices, such as heating the
supply gas or adding a de-icing agent to
the supply gas.
7. The PRX Series pilot connections are 1/4 NPT.
Connect a downstream control (sense) line to a
straight run of pipe 6 to 10 pipe diameters from the
regulator outlet as shown in Figure 3, using
3/8 in. / 9.5 mm or larger outside diameter tubing.
If such a distance is not practical, connect the
control line away from elbows, swages, nipples
or any area where abnormal ow velocities occur.
Connect the other end of the control line to the “A”
port on the bottom of the PRX Series pilot.
Note
The optimal location for the sense and
bleed lines is between the regulator and
the downstream block valve. To prevent
damage to the pilot during startup, the
sense and bleed lines should be located
on the same side of the downstream
block valve.

Type FL
North America Only

CAUTION
To prevent damage to the pilot during
startup, the sense and bleed lines
should be located on the same side of
the downstream block valve.
8. The PRX Series pilot connections are 1/4 NPT.
Connect a downstream bleed line from the “S” port
on the PRX Series pilot to a straight run of pipe 6
to 10 pipe diameters from the regulator outlet as
shown in Figure 3, using 3/8 in. / 9.5 mm or larger
outside diameter tubing.
9. Install hand valves in the downstream sense and
bleed lines if desired. If hand valves are installed,
they should be full ow valves, such as a full port
ball valve.
10. For optional remote pneumatic loading of a
PRX Series pilot, make the spring case piping
connections just as they would be made for
remote venting.
11. If extra support is needed for the Type FL regulator
due to its weight, then support the regulator using
a Y-style support underneath the inlet body cover
(key 11) and the outlet body cover (key 13).
Wide-Open Monitor Regulator
1. Follow the procedures in the All Installations section
and then continue with step 2 of this section. The
sense and bleed control lines of both the upstream
and downstream pilots will be connected to the
downstream piping (see Figure 3).
2. Connect the pilot supply line for the downstream
regulator to the outlet “R” port of the Type SA/2
pilot supply lter regulator (both upstream and
downstream pilots are connected to a single
Type SA/2).
Working Monitor Regulator
1. Follow the procedure in the All Installations
section and then continue with step 2 of
this section. The sense line of the upstream
monitor pilot and the bleed and sense lines of
the downstream pilot will be connected to the
downstream piping (see Figure 3).
2. Connect an inlet supply line from the upstream
piping to the inlet “M” port of the downstream
Type SA/2 pilot supply lter regulator.
3. Connect a control (sense) line from the “A” port
of the upstream working PRX Series pilot to the
intermediate pressure portion of piping, using
3/8 in. / 9.5 mm or larger outside diameter tubing.
4. Connect a downstream bleed line from the “S” port
of the upstream working PRX Series pilot to the
intermediate pressure portion of piping, using
3/8 in. / 9.5 mm or larger outside diameter tubing.
Startup and Adjustment
Pre-startup Considerations
Each regulator is factory-set for the outlet pressure
specied on the order. If no setting was specied,
outlet pressure was factory-set at the mid-range of
the pilot control spring. Before beginning the startup
procedure in this section, make sure the following
conditions are in effect:
• Block valves isolate the regulator
• Vent valves are closed
• A bypass, if any, is in operation
In all cases, check the control spring setting to make
sure it is correct for the application.
CAUTION
Be sure to slowly introduce pressure
into the system to prevent downstream
overpressure due to potential rapid
pressure increase. Pressure gauges
should always be used 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
When using a Type SA/2 pilot supply
lter regulator, the differential pressure
across the regulator must be at least
45 psid / 3.1 bar d for optimum regulator
performance. The Type SA/2 can be
removed if differential pressure across the
regulator is less than 45 psid / 3.1 bar d
and inlet pressure stays at or below
200 psig / 13.8 bar.

Startup
1. Make sure all block valves, vent valves and
control line valve(s) are closed.
2. Back out the pilot adjusting screw(s).
3. Slowly open the valves in the following order:
a. Pilot supply and control line valve(s), if used
b. Inlet block valves
4. Crack open the outlet block valve or bypass valve
to allow minimum ow.
5. For a single regulator, set the pilot to the desired
outlet (control) pressure according to the Pilot
Adjustment procedure.
For a single regulator with a Type PRX/131 pilot,
turn the adjusting screw on the Type PRX/131 all the
way into the spring case. Adjust the Type PRX/120
pilot to the desired setpoint of the Type PRX/131,
which should be 5 to 10 psi / 0.34 to 0.69 bar above
the desired Type PRX/120 control pressure. Adjust the
three-way valve (key 77) to vent-to-atmosphere to be
able to hear when gas starts owing from the port. Turn
the Type PRX/131 out of the spring case until you hear
audible ow, then return the three-way valve handle to
vent downstream. Then adjust the Type PRX/120 pilot
to the desired outlet (control) pressure according to the
Pilot Adjustment procedure.
For a wide-open downstream monitor installation,
adjust the upstream working pilot until intermediate
pressure is higher than the desired setpoint of the
monitor pilot. Adjust the downstream monitoring pilot to
the desired monitoring takeover pressure. Reduce the
upstream pilot to the normal outlet pressure setting.
For a wide-open upstream monitor installation,
adjust the downstream working pilot to a setpoint
higher than the setpoint of the monitor pilot. Adjust the
upstream monitoring pilot to the desired monitoring
takeover pressure. Reduce the downstream pilot to the
normal outlet pressure setting.
For a working monitor installation, adjust the
setpoint of the upstream monitor pilot to the desired
maximum pressure. Adjust the upstream working pilot
to the desired intermediate pressure setting. Adjust the
downstream pilot to a pressure setting slightly above
the upstream monitor pilot pressure setting. Adjust the
upstream monitor pilot to its desired setpoint. Establish
nal desired downstream pressure by adjusting the
downstream working regulator pilot.
For a wide-open monitor installation with a
Type PRX/131 pilot (Figure 3), turn the adjusting
screw on the Type PRX/131 all the way into the spring
case. Adjust the Type PRX/120 working pilot to a
setpoint higher than the Type PRX/120 monitor pilot.
Set the Type PRX/120 monitor pilot to the desired
setpoint of the Type PRX/131 pilot, which should be
5 to 10 psi / 0.34 to 0.69 bar above the monitor pilot
setpoint. Adjust the three-way valve (key 77) to vent to
atmosphere to be able to hear when gas starts owing
from the port. Turn the Type PRX/131 adjusting screw
out of the spring case until you hear audible ow, then
return the three-way valve handle to vent downstream.
Reduce the Type PRX/120 monitor pilot to the desired
monitor takeover pressure. Reduce the Type PRX/120
working pilot to the normal outlet pressure setting.
6. After adjusting the PRX Series pilot(s) to the
desired pressure setting(s), slowly open the
downstream block valve wide open.
7. Close the bypass valve, if used.
Pilot Adjustment
The adjustment of the regulators is performed by
means of the pilot adjustment screw, which varies
the compression of the control spring. Adjustment is
performed while the regulator is in in operation with
the aid of a pressure gauge to monitor downstream
pressure. The shutoff valve downstream of the
regulator must not be completely closed, as it
is necessary that a small quantity of gas ows
downstream to allow the outlet side to vent, when it is
necessary to lower the pressure.
For PRX Series pilot (Figure 10), loosen locknut
(key 2) and turn the adjusting screw into the spring
case (clockwise) to increase and out of the spring
case (counterclockwise) to decrease the downstream
pressure. When the desired setpoint adjustment is
completed and veried, tighten the locknut to lock the
adjusting screw in position.
No adjustment is needed to the Type SA/2 pilot supply
lter regulator.
Adjusting the monitor regulator (Figure 3) is the same
as adjusting the main regulator. Monitor setpoints
are set slightly higher than the main regulator. The
monitor pressure setting should be adjusted so it is at
minimum two times the pilot accuracy band pressure
above the working regulator pressure setting.
PRX Series Pilot Restrictor and Damper
Screw Adjustment
Note
The Type PRX/125 (upstream monitor
pilot in working monitor installations)
does not have a restrictor screw.
10
Type FL
North America Only

The Restrictor and Damper screws on the PRX Series
pilot control the regulator’s proportional band (droop)
and speed of response. To tune, follow the steps
outlined below:
1. Start with the restrictor screw 1 turn
counterclockwise from fully seated (turn restrictor
fully clockwise then 1 turn counterclockwise) and
the damper screw fully counterclockwise.
2. Turn damper screw clockwise until desired
performance is achieved. This reduces the ow path
of the damper. If the damper becomes fully seated
(no longer able to turn clockwise) and the desired
performance has not been achieved, return the
damper screw to the fully counterclockwise position.
3. Turn the restrictor screw an additional turn
counterclockwise from fully seated. This increases
the ow path of the restrictor. If additional tuning
is required, repeat step 2. Follow this method until
desired performance is achieved.
Shutdown
CAUTION
If the pilot bleed control line pressure is
shut down rst, the downstream system
may be subjected to full inlet pressure.
1. If the pilot setting must be disturbed, be sure to
keep some tension on the spring. This will prevent
trapping inlet pressure during blow down.
2. Slowly close the valves in the following order:
a. Inlet block valve
b. Outlet block valve
c. Control line valve(s), if used.
3. Open the vent valves to depressurize the system.
Maintenance
The regulator parts are subject to normal wear
and must be inspected periodically and replaced
as necessary. The frequency of inspection and
replacement depends on the severity of service
conditions and on applicable federal, state and local
codes and regulations.
!
WARNING
To avoid personal injury or property
damage from sudden release of pressure,
isolate the regulator from the pressure
system and release all pressure from the
pilot and main valve before performing
maintenance operations.
To prevent personal injury or damage
to the equipment during storage,
installation or maintenance operations,
proper supports shall be used to keep
the Type FL Regulator from rolling while
it is sitting on a at surface.
Main Valve (Refer to Figure 4)
Main Valve Pad/Disk Replacement
1. Disconnect the control lines from the regulator.
Pressurize the loading chamber in the regulator
with 15 psig / 1.0 bar. This will force the spring
back and make it easier to work on the regulator.
2. Remove outlet ange (key 22) by removing socket
head cap screws (key 5).
3. Remove pad/disk holder assembly and O-ring
(key 18). For NPS 8 and 10 / DN 200 and 250,

Type FL Travel Indicator Maintenance
A new and improved version of the travel indicator has
been phased in during 2013. The new version improves
the O-ring stem seal to minimize leakage and extend
service life. The components of the legacy and new
versions are not interchangeable. If maintenance is
performed on the travel indicator, it is recommended to
replace the entire travel indicator assembly with the new
version. Part numbers for the assemblies are shown in
the parts list. Figure 5 shows the difference between the
designs. The spare parts kits will support either design.
Take care to use the correct O-ring (key 37A or 37B)
when performing maintenance, see parts list for the
appropriate part number.
