Introduction
Scope of the Manual
This manual provides instructions for installation,
adjustment, maintenance, and parts ordering information
for the Type FL relief valve or backpressure regulator
with a Type PRX/182 pilot sold in North America. Any
accessories used with this relief valve or backpressure
regulator are covered in their respective manuals.
Description
The Type FL relief valve or backpressure regulator are
accurate pilot-operated, relief valve or backpressure
regulators designed for high-pressure transmission/city gate,
large capacity distribution systems, and power plant feeds.
The Type FL relief provides smooth, reliable operation, tight
shutoff, and long life. The main valve actuator moves in
response to the pilot loading pressure to control upstream
system pressure.
Principle of Operation
A pressure relief valve is a throttling pressure control
device that opens and closes to ensure the inlet pressure
does not rise above a predetermined pressure. Tartarini™
relief valves cannot be used as ASME safety relief valves.
A backpressure regulator is a device that controls and
responds to changes in the upstream pressure. It functions
the same as a relief valve in such a way that it opens on
increasing upstream pressure.
Relief Valve
As long as the inlet pressure is below the set pressure,
the pilot control spring keeps the pilot valve plug closed. Inlet
pressure passes through the restrictor and registers as loading
pressure on the main valve diaphragm chamber. Force from

the main spring, in addition to pilot loading pressure, provide
loading pressure to keep the main valve diaphragm and plug
assembly tightly shut off.
When the inlet pressure rises above the set pressure,
the pressure on the pilot diaphragm overcomes the pilot
control spring and opens the pilot valve plug. The pilot
then exhausts the loading pressure from the main valve
diaphragm chamber. The pilot continuously exhausts gas
when the inlet pressure is above the set pressure. The inlet
pressure unbalance overcomes the main spring force and
opens the diaphragm and plug assembly.
As the inlet pressure drops below the set pressure, the pilot
control spring closes the pilot valve plug and the exhaust to
atmosphere stops. Force from the main spring, along with pilot
loading pressure, pushes the diaphragm and plug assembly
onto the knife-edged seat, producing tight shutoff.
Backpressure Regulator
As long as inlet pressure remains below setpoint, the pilot
control spring keeps the pilot valve plug closed. Inlet pressure
passes through the upper port around the upper portion of the
valve plug and then through the hollow passage in that valve
plug. Force from the main spring, in addition to pilot loading
pressure, provide downward loading pressure to keep the main
valve diaphragm and plug assembly tightly shut off. When inlet
pressure rises above the set pressure, pressure on the pilot
diaphragm overcomes the control spring to close the upper
port and stroke the valve plug to open the lower port. The pilot
exhausts loading pressure from the main valve diaphragm
chamber. Inlet pressure unbalance overcomes the main spring
force to open the diaphragm and plug assembly.
While the main valve is throttling, the upper port of the pilot
stays closed. The pilot exhausts only when it repositions the
main valve. As inlet pressure drops below setpoint, the pilot
control spring overcomes the diaphragm force to stroke the
valve plug down to close the lower port and open the upper
port. Force from the main spring, along with pilot loading
pressure, pushes the diaphragm and plug assembly onto the
knife-edged seat, producing tight shutoff.
Installation
!
WARNING
Personal injury or equipment damage, due
to bursting of pressure-containing parts may
result if this relief valve or backpressure
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 relief
valve or backpressure 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.
1. Only personnel qualied through training and
experience should install, operate, and maintain a relief
valve or backpressure regulator. Before installation,
make sure that there is no damage to, or debris in
the main valve body or pilot. Also, make sure that all
tubing and piping are clean and unobstructed.
CAUTION
After assembly, check for shutoff and
leakage to atmosphere.
2. A Type FL relief valve or backpressure regulator may
be installed in any orientation, as long as ow through
matches the direction of the arrow on the main
valve body.
3. Apply a good grade of pipe compound to the external
pipeline threads for a screwed body, or use suitable
line gaskets for a anged body. Use approved piping
procedures when installing the valve.
!
WARNING
When used in relief valve service, the Type FL
main valve and pilot both exhaust gas. In
hazardous or ammable gas service, personal
injury, death, or property damage may occur
due to re or explosion of vented gas that
has accumulated. To prevent such injury or
damage, provide piping or tubing to vent the
gas to a safe location. The exhaust piping
must be designed and installed to guard
against excessive ow restriction. This piping
must be protected against condensation or
debris that could clog it.
For safety during shutdown, vent valves
are required immediately upstream
and downstream of the main valve on a
backpressure or bypass installation.
4. If system operation during maintenance is required,
install isolating and vent valves as needed.

5
Type FL
5. If the vent assembly (key 12, Figure 7) remains in the
pilot body, then it must be pointed down if possible or
otherwise protected. If the exhaust is to be piped to
the main valve exhaust or remotely vented, remove
the vent assembly and install tubing or piping into
the 1/4 NPT pilot exhaust connection. There are two
vent connections need to be piped away. Protect the
open end of the exhaust pipe by installing a screened
vent cap.
6. The pilot spring case vent (key 12, Figure 7) must be
kept open to atmospheric pressure. Protect the vent
assembly from icing, moisture, or debris that may cause
blockage, as required. To change the vent orientation,
twist the vent assembly in the spring case. To remotely
vent the pilot spring case, pilot body vent need to be pipe
away as well and install tubing or piping into the 1/4 NPT
spring case vent tapping. Protect the open end of the
vent line by installing a screened vent cap.
7. The Type PRX pilot connections are 1/4 NPT. Connect
the inlet control (sense) line from the “A” port, Figure 6
(key 55), on the bottom of the Type PRX pilot to a straight
run of pipe 6 to 10 pipe diameters from the relief valve or
backpressure regulator inlet as shown in Figure 2, using
3/8 inch / 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.
Startup and Shutdown
CAUTION
If pressure is introduced rst to the main
valve before the pilot, the main valve may
go wide-open and subject the downstream
system to full inlet pressure.
Note
The maximum inlet pressure for specic
constructions are given in Table 1. Use a
pressure gauge to monitor inlet pressure
during startup.
Relief Installation
Startup
1. Close vent valve (not shown).
2. Slowly open block valve and hand valve, if installed.
3. Adjust the pilot as needed.
Shutdown
1. Close block valve and hand valve, if installed.
2. Slowly open vent valve (not shown).
Backpressure Installation
Startup
1. Close upstream and downstream vent valves
(not shown).
2. Slowly open upstream block valve rst and then slowly
open downstream block valve.
3. Adjust the pilot as needed. If the pilot is not piped
downstream, make sure the pilot exhaust is pointed in
the correct direction.
Shutdown
1. Close upstream block valve rst and then close the
downstream block valve.
2. Open downstream and upstream vent valves
(not shown).
Pilot Adjustment (See Figure 7)
If set pressure adjustment is necessary, monitor relief (inlet)
pressure with a gauge during the adjustment procedure.
Loosen the locknut (key 2). Turn the adjusting screw (key 1)
into the spring case to increase the set pressure. Turn
the adjusting screw out of the spring case to decrease the
set pressure. When adjustment is completed, tighten the
locknut to lock the adjusting screw in position.
The adjustment of the relief valve or backpressure
regulator is performed by means of the pilot adjusting
screw, which varies the compression of the control spring.
Maintenance
The relief valve and backpressure 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. Use only
replacement parts manufactured or furnished by Tartarini™.
!
WARNING
To avoid personal injury or property damage
from sudden release of pressure, isolate
the relief valve or backpressure 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 relief valve
or backpressure regulator from rolling while
it is sitting on a at surface.
