DANGER — Immediate hazards
which WILL result in severe
personal injury or death.
WARNING — Hazards or unsafe
practices which COULD result
in severe personal injury or
death.
CAUTION — Hazards or unsafe
practices which COULD result
in minor personal injury.
ATTENTION — Hazards or
unsafe practices which COULD
result in product or property
damage
If and when required, appropriate safety labels have been included in
the rectangular margin blocks throughout this manual. Safety labels are
vertically oriented rectangles as shown in the representative examples
(below), consisting of three panels encircled by a narrow border. The
panels can contain four messages which communicate:
• The level of hazard seriousness
• The nature of the hazard
• The consequence of human, or product, interaction with the hazard
• The instructions, if necessary, on how to avoid the hazard
The top panel of the format contains a signal word (DANGER, WARNING,
CAUTION or ATTENTION) which communicates the level of hazard
seriousness.
The center panel contains a pictorial which communicates the nature of
the hazard, and the possible consequence of human or product interaction
with the hazard. In some instances of human hazards the pictorial may,
instead, depict what preventive measures to take, such as wearing
personal protective equipment.
The bottom panel may contain an instruction message on how to avoid
the hazard. In the case of human hazard, this message may also contain
a more precise denition of the hazard, and the consequences of human
interaction with the hazard, than can be communicated solely by the
pictorial.

II. Safety Alerts
Read - Understand - Practice
Danger Alerts
A DANGER alert describes actions that may cause
severe personal injury or death. In addition, it may provide
preventive measures to avoid severe personal injury or
death.
DANGER alerts are not all-inclusive. Baker Hughes cannot
know all conceivable service methods nor evaluate all
potential hazards. Dangers include:
• High temperature/pressure can cause injury. Ensure all
system pressure is absent before repairing or removing
valves.
• Do not stand in front of a valve outlet when discharging.
STAND CLEAR OF VALVE to avoid exposure to trapped,
corrosive media.
• Exercise extreme caution when inspecting a pressure
relief valve for leakage.
• Allow the system to cool to room temperature before
cleaning, servicing, or repairing. Hot components or
uids can cause severe personal injury or death.
• Always read and comply with safety labels on all
containers. Do not remove or deface container labels.
Improper handling or misuse could result in severe
personal injury or death.
• Never use pressurized uids/gas/air to clean clothing
or body parts. Never use body parts to check for leaks,
ow rates, or areas. Pressurized uids/gas/air injected
into or near the body can cause severe personal injury
or death.
• It is the owner’s responsibility to specify and provide
personal protective wear to protect persons from
pressurized or heated parts. Contact with pressurized
or heated parts can result in severe personal injury or
death.
• Do not work or allow anyone under the inuence of
intoxicants or narcotics to work on or around pressurized
systems. Workers under the inuence of intoxicants
or narcotics are a hazard to themselves and other
employees. Actions taken by an intoxicated employee
can result in severe personal injury or death to
themselves or others.
• Always perform correct service and repair. Incorrect
service and repair can result in product or property
damage or severe personal injury or death.
• Always use the correct tool for a job. The misuse of a
tool or the use of an improper tool can result in personal
injury, damage to product or property.
• Ensure the proper “health physics” procedures are
followed, if applicable, before starting operation in a
radioactive environment.
Caution Alerts
A CAUTION alert describes actions that may result in a
personal injury. In addition, they may describe preventive
measures that must be taken to avoid personal injury.
Cautions include:
• Heed all service manual warnings. Read installation
instructions before installing valve(s).
• Wear hearing protection when testing or operating
valves.
• Wear appropriate eye and clothing protection.
• Wear protective breathing apparatus to protect against
toxic materials.

Proper installation and start-up is essential to the safe and reliable operation of all valve
products. The relevant procedures recommended by Baker Hughes, and described in
these instructions, are e󰀨ective methods of performing the required tasks.
It is important to note that these instructions contain various “safety messages” which
should be carefully read in order to minimize the risk of personal injury, or the possibility
that improper procedures will be followed which may damage the involved Baker
Hughes product, or render it unsafe. It is also important to understand that these “safety
messages” are not exhaustive. Baker Hughes cannot possibly know, evaluate, and
advise any customer of all of the conceivable ways in which tasks might be performed,
or of the possible hazardous consequences of each way. Consequently, Baker Hughes
has not undertaken any such broad evaluation and, thus, anyone who uses a procedure
and/or tool, which is not recommended by Baker Hughes, or deviates from Baker Hughes
recommendations, must be thoroughly satised that neither personal safety, nor valve
safety, will be jeopardized by the method and/or tools selected. Contact Baker Hughes if
there are any questions relative to tools/ methods.
The installation and start-up of valves and/or valve products may involve proximity to
uids at extremely high pressure and/or temperature. Consequently, every precaution
should be taken to prevent injury to personnel during the performance of any procedure.
These precautions should consist of, but are not limited to, ear drum protection, eye
protection, and the use of protective clothing, (i.e., gloves, etc.) when personnel are
in, or around, a valve work area. Due to the various circumstances and conditions in
which these operations may be performed on Baker Hughes products, and the possible
hazardous consequences of each way, Baker Hughes cannot possibly evaluate all
conditions that might injure personnel or equipment. Nevertheless, Baker Hughes does
o󰀨er certain Safety Alerts, listed in Section II, for customer information only.
It is the responsibility of the purchaser or user of Consolidated valves/ equipment to
adequately train all personnel who will be working with the involved valves/equipment.
For more information on training schedules, please contact your local Green Tag
Center. Further, prior to working with the involved valves/equipment, personnel who
are to perform such work should become thoroughly familiar with the contents of these
instructions.
Wear necessary personal
protective equipment to
prevent possible injury
III. Safety Notice

8 | Baker Hughes © 2020 Baker Hughes Company. All rights reserved.
V. Terminology for Safety Relief
Valves (SRV)
1. Accumulation
The pressure increase over the maximum allowable working
pressure of the vessel during discharge through the SRV,
expressed as a percentage of that pressure or in actual
pressure units.
2. Backpressure
The pressure on the discharge side of the SRV:
a. Built-up Backpressure - the pressure that develops at the
valve outlet, after the SRV has been opened, as a result
of ow.
b. Superimposed Backpressure - the pressure in the
discharge header before the SRV is opened.
3. Constant Backpressure
The superimposed backpressure that is constant with time.
4. Variable Backpressure
The superimposed backpressure that varies with time.
5. Blowdown
The di󰀨erence between set pressure and re-seating
pressure of the SRV, expressed as a percentage of the set
pressure or in actual pressure units.
6.ColdDi󰀨erentialSetPressure
The pressure at which the valve is adjusted to open on the
test stand. This pressure
includes the corrections
for backpressure and/
or temperature service
conditions.
Di󰀨erential Between Operating and Set Pressures Valves- in
installed process services will generally give best results if
the operating pressure does not exceed 90 percent of the
set pressure. However, on pump and compressor discharge
lines, the di󰀨erential required between the operating and set
pressures may be greater because of pressure pulsations
coming from a reciprocating piston. The valve should be set
as far above the operating pressure as possible.
7. Lift
The actual travel of the disc away from the closed position
when a valve is relieving.
8. Maximum Allowable Working Pressure
The maximum gauge pressure permissible in a vessel
at a designated temperature. A vessel may not be
operated above this pressure, or its equivalent, at any
metal temperature other than that used in its design.
Consequently, for that metal temperature, it is the highest
pressure at which the primary pressure SRV is set to open.

V. Terminology for Safety Relief Valves (Contd.)
9. Operating Pressure
The gauge pressure to which the vessel is normally
subjected in service. A suitable margin is provided between
operating pressure and maximum allowable working
pressure. For assured safe operation, the operating pressure
should be at least 10 percent under the maximum allowable
working pressure or 5 psi (.34 bar), whichever is greater.
10. Overpressure
A pressure increase over the set pressure of the primary
relieving device. Overpressure is similar to accumulation
when the relieving device is set at the maximum allowable
working pressure of the vessel. Normally, overpressure is
expressed as a percentage of set pressure.
11. Rated Capacity
The percentage of measured ow at an authorized percent
overpressure permitted by the applicable code. Rated
capacity is generally expressed in pounds per hour (lb/hr) for
vapors, standard cubic feet per minute (SCFM) or m3/min for
gases, and in gallons per minute (GPM) for liquids.
12. Relief Valve
An automatic pressure-relieving device, actuated by static
pressure upstream from the valve. A relief valve is used
primarily for liquid service.
13. Safety Relief Valve (SRV)
An automatic pressure-relieving device used as either a
safety or relief valve, depending upon application. The SRV
is used to protect personnel and equipment by preventing
excessive overpressure.
14. Safety Valve
An automatic pressure-relieving device actuated by the static
pressure upstream of the valve, and characterized by a rapid
opening or “pop” action. It is used for steam, gas, or vapor
service.
15. Set Pressure
The gauge pressure at the valve inlet for which the relief
valve has been adjusted to open under service conditions. In
liquid service, the inlet pressure at which the valve starts to
discharge determines set pressure. In gas or vapor service,
the inlet pressure at which the valve pops determines the set
pressure.
16. Simmer
The audible passage of a gas or vapor across the seating
surfaces just before “pop.” The di󰀨erence between this start-
to-open pressure and the set pressure is called “simmer.”
Simmer is generally expressed as a percentage of set
pressure.
VI. Handling, Storage
Handling
Valves should not be shipped with the inlet ange down.
These valves should be kept in their factory foam-lled car-
ton until installation.
ATTENTION!!
Never lift the valve by the lifting lever.
ATTENTION!!
Handle carefully. Do not drop or strike the valve.
Do not subject SRVs, either crated or uncrated, to sharp
impact. Ensure that the valve is not bumped or dropped
during loading or unloading from a truck. While hoisting the
valve, take care to prevent bumping the valve against steel
structures and other objects.
ATTENTION!!
Prevent dust and debris from entering inlet or
outlet of the valve.
Storage
Store SRVs in a dry environment and protect them from the
weather. Do not remove the valve from the skids or crates
until immediately before installation.
Do not remove ange protectors and seating plugs until the
valve is ready to be bolted into place during the installation.
Screwed/portable valves should be kept in their factory foam-
lled carton until installation to avoid damage to external inlet
threads.

VII. Pre-Installation and Installation Instructions
When SRVs are uncrated and the ange protectors or sealing plugs are removed, exercise meticulous care to prevent dirt and
other foreign materials from entering the inlet and outlet ports while bolting the valve in place.
VIII. Design Features and Nomenclature
A. General Information
The Consolidated 19000 Series Portable Safety Relief Valve
has 316 stainless steel trim as standard material. Reliable
performance and easy maintenance procedures are
characteristics of this valve, when properly installed in
suitable applications for its design.
The Consolidated 19000 Series SRV has three pressure
classes—19000L 5-290 psig (0.34-19.99 barg), 19000M
291-2000 psig (20.06-137.90 barg) and 19000H 2001
psig (137.96 barg) and up. Standard Consolidated 19000
Series parts are used for both liquid applications and gas
applications. It is designed for short blowdown on all types
of media, typically less than 10 percent.
All Consolidated 19000 Series safety relief valves have
xed blowdown. This means that the parts are designed so
that there is no blowdown adjustment required when setting
or testing the valve.
B. Design Options
B.1 Consolidated 19000 Series MS & DA
Safety Relief Valves
O-Ring Seat Seal Valves
All Consolidated 19000 Series Valves are available with an
O-ring seat seal as a design option. This optional design is
bubble tight at 97 percent of set pressures over 100 psig
(6.89 barg), in order to meet application requirements
beyond the normal capabilities of metal to metal seat
valves. Consolidated Series 19000 valves with the O-ring
seat seal option are identied by the su󰀩x DA, see Table
14.
Lifting Levers, Caps and Gags
All Consolidated 19000 Series Valves are designed so that
eld conversion from the standard screwed cap to a plain
lifting lever cap, or to a packed lifting lever cap (or vice
versa), does not require valve disassembly or resetting.
The lifting lever option is designed to open the valve at
75 percent of the valve set pressure, in compliance with
ASME Code Section VIII. Further, all available Consolidated
19000 Series Valve caps may be equipped with a gag upon
customer request.
Inlet/Outlet Connections
All Consolidated 19000 Series can be provided by Baker
Hughes Consolidated with anged, or socket weld inlet and
outlet connections, upon customer request.
B.2 19096M-DA-BP Safety Relief Valves
(See Figure 6)
In this design, the bonnet and the spindle are di󰀨erent—there
are two added parts and two additional O-rings. The bonnet
is a two-piece design rather than a one-piece. The top of the
bonnet (7) is the male piece and it screws into the female
bottom bonnet (8). The bottom bonnet has a machined shelf in
the top on which a metal backup plate (39) seats via an O-ring
(40), part number 310XX030. (The “XX” in the part number
designates the material and durometer of the O-ring.) The
spindle (9) is modied to have a larger diameter in the lower
section to accommodate a 310XX011 O-ring (40), which slides
through the inside diameter of the backup plate (39), providing
an area nearly equal to the area of the base which balances
the e󰀨ects of the back pressure.
C. Nomenclature
Applicable valve nomenclature for Types Consolidated
19000 Series Male and Female inlet congurations
are illustrated in Figures 1 through 6. Relevant parts
nomenclature for optional lifting levers, caps and the gag,
as applicable, are provided in Figures 1 through 6.

IX. Introduction
A. 19000 MS & DA
Safety Relief Valves
Consolidated Series 19000 Portable Pressure Relief Valves
are designed to meet ASME Section VIII requirements for
xed blowdown pressure relief valves and liquid relief valves.
They may be used for various media such as air, liquids,
process steam and hydrocarbons and may serve as either a
safety valve or a relief valve, depending upon the application.
B. 19096M-DA-BP
Safety Relief Valves
The 19000 back pressure version is only available in the .096"
(2.44 mm) orice with an O-ring seat. It is available for steam,
liquid or gas applications and may be furnished with a plain
or screwed cap. The 19096M-DA-BP variation is furnished as
a 19096M designation with a pressure range of 50-2000 psig
(3.45-137.90 barg). The standard medium pressure valve is
limited to a minimum of 290 psig (19.99 barg) in the standard
19000 design. The designation will be used since most of the
parts are from the 19096M bill of material.

XI. Recommended Installation Practices
A. Mounting Position
Mount SRVs in a vertical (upright) position (in accordance with API RP 530). Installing a
safety relief valve in any position other than vertical (±1 degree) will adversely a󰀨ect its
operation as a result of the induced misalignment of moving parts.
A stop valve may be placed between the pressure vessel and its relief valve only as
permitted by code regulations. If a stop valve is located between the pressure vessel and
SRV, the stop valve port area should equal or exceed the nominal internal area associated
with the pipe size of the SRV inlet. The pressure drop from the vessel to the SRV shall not
exceed three (3) percent of the valve’s set pressure, when owing at full capacity.
The threaded inlet and outlet ports and sealing faces of the valve and all connecting
piping must be free from dirt, sediment and scale.
In the case of screwed/portable valves, use caution to avoid unscrewing bonnet from the
base; if a pipe wrench is used to install or remove the base, ensure that the wrench is
placed on the ats of the base and not on the bonnet. If the bonnet/ base joint is broken,
the valve should be retested to ensure proper set pressure and function of the valve.
Position SRVs for easy access and/or removal so that servicing can be properly
performed. Ensure su󰀩cient working space is provided around and above the valve.
B. Inlet Piping
The inlet piping (see Figure 7) to the valve should be short and directly from the vessel
or equipment being protected. The radius of the connection to the vessel should permit
smooth ow to the valve. Avoid sharp corners. If this is not practical, then the inlet should
be at least one additional pipe diameter larger.
The pressure drop from the vessel to the valve shall not exceed three (3) percent
of valve set pressure when the valve is allowing full capacity ow. The inlet piping
should never be smaller in diameter than the inlet connection of the valve. Excessive
pressure drop in gas, vapor, or ashing-liquid service at the inlet of the SRV will cause
the extremely rapid opening and closing of the valve, which is known as “chattering.”
Chattering will result in lowered capacity and damage to the seating surfaces. The most
desirable installation is that in which the nominal size of the inlet piping is the same as,
or greater than, the nominal size of the valve inlet ange and in which the length does
not exceed the face-to-face dimensions of a standard tee of the required pressure class.
Do not locate SRV inlets where excessive turbulence is present, such as near elbows,
tees, bends, orice plates or throttling valves.
Section VIII of the ASME Boiler and Pressure Vessel Code requires the inlet connection
design to consider stress conditions during valve operation, caused by external loading,
vibration, and loads due to thermal expansion of the discharge piping.
The determination of reaction forces during valve discharge is the responsibility of the
vessel and/or piping designer. Baker Hughes publishes certain technical information
about reaction forces under various uid ow conditions, but assumes no liability for the
calculations and design of the inlet piping.
External loading, by poorly designed discharge piping and support systems, and forced
alignment of discharge piping can cause excessive stresses and distortions in the valve
as well as the inlet piping. The stresses in the valve may cause a malfunction or leak.
Therefore, discharge piping must be independently supported and carefully aligned.
Heed all service
manual warnings. Read
installation instructions
before installing valve(s).
Do not mount valve at
the end of pipe through
which there is normally
noowornearelbows,
tees, bends, etc.
Mount safety relief valves
in a vertical, upright
position only.

XI. Recommended Installation Practices (Contd.)
Vibrations in the inlet piping systems may cause valve seat
leakage and/or fatigue failure. These vibrations may cause
the disc seat to slide back and forth across the base seat
and may result in damage to the seating surfaces. Also,
vibration may cause separation of the seating surfaces and
premature wear to valve parts. High-frequency vibrations
are more detrimental to SRV tightness than low-frequency
vibrations. This e󰀨ect can be minimized by providing a larger
di󰀨erence between the operating pressure of the system
and the set pressure of the valve, particularly under high
frequency conditions.
Temperature changes in the discharge piping may be
caused by uid ow in from the discharge of the valve or by
prolonged exposure to the sun or heat radiated from nearby
equipment. A change in the discharge piping temperature will
cause a change in the length of the piping, which may cause
stresses to be transmitted to the
SRV and its inlet piping. Proper
support, anchoring or provision for
exibility of the discharge piping
can prevent stresses caused by
thermal changes. Do not use xed
supports.
C. Outlet Piping
Alignment of the internal parts of
the SRV is important to ensure
proper operation (see Figure
8). Although the valve body
will withstand a considerable
mechanical load, unsupported
discharge piping consisting of
more than a companion ange long-radius elbow, and a
short vertical pipe is not recommended. Use spring supports
to connect outlet piping to prevent thermal expansion from
creating strains on the valve. The discharge piping should be
designed to allow for vessel expansion as well as expansion
of the discharge pipe itself. This is particularly important on
long distance lines.
A continual oscillation of the discharge piping (wind loads)
may induce stress distortion in the valve body. The resultant
movement of the valve’s internal parts may cause leakage.
Where possible, use properly supported drainage piping to
prevent the collection of water or corrosive liquid in the valve
body.
When two or more valves are piped to discharge into a
common header, the built-up backpressure resulting from
The pressure drop (P.D.) between the source of pressure in the protected equipment and
the pressure relief valve inlet is not to exceed 3 percent of the valve set pressure.

XII. Disassembly of 19000 Series SRV
A. General Information
Consolidated SRVs can be easily disassembled for inspection, the reconditioning of
seats or the replacement of internal parts. Appropriate set pressure can be established
after reassembly. (See Figures 1 through 6 for parts nomenclature.)
Notes:
• Before starting to disassemble the valve,
be sure there is no material pressure in the
vessel.
• Many pressure vessels that are protected
by Consolidated safety relief valves contain
dangerous materials.
• Decontaminate and clean the valve inlet and
outlet and all external surfaces in accordance
with the cleaning and decontaminating
recommendations in the appropriate Material
Safety Data Sheet.
• Parts from one valve should not be
interchanged with parts from another valve.

recommendations in the
appropriate Material Safety

ATTENTION!!
Do not interchange parts from one valve with
parts from another valve.
the opening of one (or more) valve(s) may cause a superimposed backpressure in
the remaining valves. Under these conditions, the use of the 19096-DA-BP model is
recommended.
In every case, the nominal discharge pipe size should be at least as large as the nominal
size of the SRV outlet ange. In the case of long discharge piping, the nominal discharge
pipe size must sometimes be much larger.
As a nal point, the discharge piping size is never less than the size of the valve outlet,
nor heavier than schedule 40 pipe size. In addition, the discharge piping must be
designed to limit the total backpressure to a maximum of 10 percent of the valve set
pressure, or 400 psig (27.58 barg), whichever is smaller.
ATTENTION!!
Undersized discharge piping could create
built-up backpressure.
