Main Valve Materials
3900 Series Valve Materials Overview
The main valve has six basic components. Assembly and
disassembly are accomplished through top entry. As long
as there is no pressure in the system, routine maintenance,
such as replacement of O-rings and seals, can done with the
valve in place, eliminating the need for cranes and additional
manpower.
There are three essentials to a tighter and more secure seal:
1.
Concentric Alignment
The nozzle bore and O-ring retainer are both machined
to an angle of 50 degrees. This ensures that as the valve
disc opens and closes the O-ring is aligned concentrically
against the lip of the nozzle. Close tolerance between the
nozzle and the body also helps to ensure a tight seal when
the valve is closed.
2.
Maximum Sealing Force
On the back side of the O-ring retainer, there are two small
slots. When the valve is closed, process media enters
between the machined seat of the nozzle and the O-ring
retainer, and proceeds up the slots behind the O-ring. This
pressure forces the O-ring against the lip of the nozzle and
the curved recess of the disc.
Base
The base is cast with integral flanges. It forms the main
structure and is a pressure boundary component, as it is
exposed to process media. To ensure integrity and reliability,
all base castings are manufactured to the latest ASME Boiler
& Pressure Vessel Codes. The standard materials are Grade
WCC carbon steel, and Grade CF8M 316 stainless steel. Other
materials such as Monel, Hastelloy, and additional codeapproved materials are available to satisfy more demanding
requirements. The discharge side of the body is drilled
and tapped for pilot venting. If the pilot is vented to the
atmosphere, a pipe plug is installed to secure this area.
As the pressure within the valve rises to the set point ,the
O-ring is pressed tightly against the nozzle to maintain
maximum sealing force until valve set pressure is reached.
Nozzle
3.
The 316 stainless steel nozzle performs two functions: It forms the
lower sealing surface, and it controls the capacity. The orifice is
machined into the nozzle, ensuring that rated flow capacities will
be obtained should an overpressure condition occur. The nozzle
is threaded or bolted into the body and sealed with an O-ring.
Threading or bolting the nozzle facilitates easy removal for repair
or replacement.
Cover Plate
Guide
This one-piece 316 stainless steel guide ensures true
alignment of the disc and nozzle for positive, bubble-tight
sealing. The heavy guide construction is designed to
prevent warping or egging when the valve is in service.
Disc
The disc is 316 stainless steel. An O-ring (part 10) is used for
isolating the dome chamber when used on air, gas or liquid
service. A spring energized Teflon® seal (part 17) is used on the
top side of the disc for steam service. A graphite impregnated
Teflon® guide ring (or rings) (part 16) provides a low coefficient
of friction for the guiding function between the disc and guide.
An O-ring seat (part 12) performs the primary sealing function
for the disc to ensure bubble tightness. The metal-to-metal
stop for the seat allows the valve to function even if the O-ring
is damaged or destroyed.
Two unique features distinguish GE's O-ring seat seal safety
relief valve from other designs. These features are the 50
degree metal-to-metal load bearing seats and the slotted
O-ring retainer.

O-ring Retention
When the valve opens, the pressure behind the O-ring
escapes from these same two slots on the O-ring retainer.
This prevents the O-ring from being ejected. Additionally, the
O-ring encapsulating retainer prevents the O-ring from being
ejected by the high velocity, low pressure discharge inside
the upper valve body.
The cover plate secures the guide and seals the main body.
Each cover plate is drilled and tapped for eye bolts which are
used for ease of assembly or disassembly of the main valve and
for handling the assembled valve.
Sensing Tube
The sensing tube is machined from 316 stainless hex bar stock
and is threaded into the main body at a location below the
nozzle. The sensing tube picks up media pressure and feeds this
pressure through the sensing line to the pilot. To ensure proper
orientation, one side of the hex is marked UP. This marking
is to be oriented upward when the valve is sitting on its inlet
flange. The pilot valve can also be installed in applications
where remote sensing of pressure is used to actuate the pilot.
In this case, the sensing tube is installed at the desired sensing
location and connected by the sensing line to the pilot. The
sensing tube port in the main valve is then sealed with a pipe
plug.
Other
The remaining parts -- studs, nuts, spring, nameplate, and
lead seal -- complete the assembly of the main valve. A wire
and lead seal are affixed to the pilot to protect the pilot valve
adjustments.

Pop Pilot Product Operation
Pop Pilot (PV)
Operating Principles and Performance
GE's MPV (Modular Pilot Valve) Pilot-Operated Safety Relief Valve is offered as both a non-flowing pop pilot and a non-flowing
modulating pilot within a single assembly. The unique modular design construction allows vented bonnet and easy field
conversion from one configuration to the other. The pilot valve operates by sensing system pressure and using this pressure to
control the closing force on the main valve disc. Increasing inlet valve pressure results in increased closing force until the pilot
valve opens. Pressure is relieved at a designated set point as process media is allowed to discharge through the main valve. Use
of the pop pilot configuration will result in a main valve disc “pop” action from the seated position to 100 percent open. When the
overpressure condition is relieved, the main valve disc will reseat due to the increased media pressure directed through the pilot
valve to the top of the valve disc (dome).

Dome
area
System pressure from the main valve inlet is fed to the dome
area by the pilot through interconnecting tubing. This equalizes
the pressure on the top of the disc with inlet pressure on the
seating surface (bottom) of the disc. Since the area of the top
of the disc is larger than the area of the seating surface, the
differential area results in a net downward force keeping the
main valve tightly closed.
As inlet pressure increases, the pilot piston strokes and seals
off the main valve inlet pressure from the dome pressure. The
pilot simultaneously opens the vent seal to relieve the dome
pressure to atmospheric pressure.
Discharge Through Main Valve
Return to Normal Position
When the discharging main valve reduces the inlet pressure
to the preset blowdown pressure of the pilot, the pilot piston
closes the vent seal. Simultaneously, the inlet seal is reopened
in the pilot. The main valve inlet pressure is again allowed
to enter the dome above the main valve disc. As the dome
pressure equalizes with the inlet pressure, the downward force
created by the differential areas of the disc closes the main
valve.
The main valve disc is allowed to lift off the seat as the fluid force
overcomes the now removed pressure load above the main valve
disc. The valve discharges to relieve system pressure.

Modulating Pilot Product Operation
Modulating Pilot (MV)
Operating Principles and Performance
GE's MPV (Modular Pilot Valve) Pilot-Operated Safety Relief
Valve is also offered as a non-flowing modulating pilot design,
using a unique modular configuration that allows for easy
field conversion from pop operation to modulating operation.
The modulating pilot operation is very similar to the pop
pilot operation with the added ability to hold a percentage
of system pressure above the main valve disc, producing a
modulating action. Increasing the system pressure results in
3900 Series SRV with Modulating Pilot
reduced closing force due to venting through the pilot valve.
Pressure relief begins at a designated set point as process
media is discharged through the main valve. However, the
actual lift of the main valve disc is based on the specific system
overpressure condition instead of “popping” instantaneously
to the 100 percent open position (as with the pop pilot). This
“modulating” action results in improved operating efficiencies
through reduced media loss and lower emissions.

Modulating Pilot Operation
MV Valve Closed (Normal Position)
Modulating Position
Dome
area
System pressure from the main valve inlet is fed to the dome
area by the pilot through interconnecting tubing. This equalizes
the pressure on the top of the disc with inlet pressure on the
seating surface (bottom) of the disc. Since the area of the top
of the disc is larger than the area of the seating surface, the
differential area results in a net downward force keeping the
main valve tightly closed.
MV Fully Open
As inlet pressure increases, the pilot piston strokes and seals
off the main valve inlet pressure from the dome pressure. The
pilot simultaneously opens the vent seal to relieve the dome
pressure to the bottom of the modulator piston. The modulator
piston has a differential area with the smaller area being on
top. The top of this piston always sees the main valve inlet
pressure. When the dome pressure is applied to the bottom of
the modulator piston, there is a net upward force. This is due to
both pressures being equal (at this point), and the lower area
is larger than the upper area. The modulator relieves pressure
from the dome to the atmosphere until force from the inlet
pressure on top of the modulator piston is sufficient to move it
to the closed position. A certain amount of pressure remains in
the dome. This pressure is controlled by the differential area in
the modulator. Since the dome pressure has not been dropped
to atmospheric pressure, the main valve only partially opens
at the set point. The modulator piston will remain closed until
the main valve disc is forced into higher lift by increasing inlet
pressure. As this occurs, the modulator piston may relieve
further pressure from the dome as necessary to achieve the
required main disc lift within 10 percent overpressure.
Return to Normal Position
As the inlet pressure increases further, the net upward force
on the main valve increases, allowing the main valve to relieve
more pressure. The disc obtains full lift (full capacity) within 10
percent of set pressure.
© 2016 General Electric Company. All rights reserved.
When the discharging valve reduces the inlet pressure to the
pre-set blowdown pressure of the pilot, the pilot piston closes
the vent seal. Simultaneously, the inlet seal is reopened in the
pilot. The main valve inlet pressure is again allowed to enter
the dome above the main valve disc. As the dome pressure
equalizes with the inlet pressure, the downward force created
by the differential areas of the disc closes the main valve.

Manual Blowdown Valve
Filters
An optional manual blowdown valve is available for relieving
the pilot-operated safety relief valve. Consult the factory
for applications requiring a pneumatic or electrical solenoid
blowdown valve, which may be connected to a distant location,
such as an operator station, for remote actuation. The blowdown
valve is ported directly to the main dome area, so that the media
in the dome is vented when the blowdown valve is actuated, thus
allowing the main valve to open.
Filter options are available for dirty applications. These filters
are installed in the pilot inlet sensing line.
For all applications on air, water over 140°F (60°C), or steam
service, ASME Section VIII - Division 1 requires each pressure
relief valve to have a lifting device such as a blowdown valve or
a means of connecting or applying pressure to the pilot to verify
that the moving parts essential to good operation are free to
move. (Reference UG 136(a)(3).)
The lifting lever or blowdown valve may be omitted under Code
Case 2203. All orders for pressure relief valves without levers
or blowdown valves for steam, air and water over 140°F (60°C)
must state specifically that the valves are being purchased per
Code Case 2203. The purchaser is responsible for obtaining
jurisdictional authorization for use of Code Case 2203.
Field Test Connection
A 1/4” FNPT field test connection is standard on all pilot valve
types. This allows the stroking of the valve with an auxiliary
media (e.g., air or nitrogen). An internal check valve is present
in the field test connection isolating the inlet media from the
test media, and at the same time, allowing the valve to open
normally in the event of a system over-pressurization during a
field test.
© 2016 General Electric Company. All rights reserved.
For the 39PV and 39MV, an optional sensing line filter is
available. This filter has a 316 stainless steel body, Teflon®
seals, and a 40-50 micron stainless steel filter element. This
filter is standard for steam service.
Other high capacity filter options include: (1) a carbon steel
cadmium coated filter body with a 35 micron stainless steel
element, (2) a stainless steel filter body, and (3) an entirely
stainless steel filter arrangement. The O-ring in the filters for
steam service will be Teflon®. These filters may be equipped
with a manually operated needle valve which allows for purging
the filtered material while the valve is in operation.
All filter elements are stainless steel, and all filters, including
carbon steel, conform to NACE Standard MR0175.
A dual filter arrangement is available for applications in which
the customer is unsure of the filter maintenance requirements.
In these cases, a preventive maintenance program may be
developed by monitoring the filters without taking the valve off
line.
Backflow Preventer
When the pilot-operated safety relief valve is not vented
directly to the atmosphere, it is possible to build up back
pressure in the discharge line. This is typical in situations
where several valves manifold into a common discharge
header. Should the discharge line pressure exceed the valve
inlet pressure, it could cause the piston to lift and allow
reverse flow through the main valve. This can be eliminated
through the use of the Backflow Preventer.
3900 MPV Series Pilot Operated Safety Relief Valve Tech Spec | 23
Pilot Design Options
Pilot Valve Tester
Pressure Differential Switch
The pilot valve test indicator is available for the modulating
and pop action pilot valves. The valve test indicator measures
the set pressure of the pilot, while maintaining pressure on
the main valve dome area; thereby, allowing only the pilot to
actuate. The system shown below is available for remote or
local testing.
Electrical: A pressure differential switch is available that may
be wired to an operator station or some other remote location.
The switch will provide a signal that indicates when the main
valve is opening. The standard pressure differential switch is
a single pole, double throw, rate at 5 amps and 30 volts DC
with a NEMA 4 enclosure. (For other configurations, consult the
factory.)

Pneumatic: For applications that do not permit an electrical
differential switch, an option is available to provide pneumatic
signal to indicate when the main valve opens.
Remote Pilot Mounting
The 39PV and 39MV pilots can be mounted separately from
the main valve. Remote pilot mounting will allow heating or
cooling the pilot in case ambient conditions are outside the
scope of the pilot. It will also enable the user to group several
pilots together for control of ambient conditions in a smaller
space. This also promotes easier maintenance.
Dual Pilots
A dual pilot arrangement is available for applications in
which the pilot valve's O-rings require monitoring and/
or maintenance more frequently than the main valve. In
this installation, the pilot valves may be alternated for
maintenance without bringing the system down.
Note:
For all option and accessory material variations, contact the factory.
Remote Sensing
The pilot valve inlet may be piped to a location remote from
the main valve. In this application, the customer may pipe
the inlet sensing line to some location other than where the
main valve is located and where the pressure will be relieved
(for tubing size and maximum length, consult factory for
recommendations).

Pilot Design Options
Dirty Service Option
Severe dirty service, precipitation and viscous fluid problems
can be solved using the dirty service option offered on the
3900 Series POSRV. A dirty service option can be added to
the standard pilot valve. The kit contains a 316 SS chamber,
an isolation seal and an extended pilot piston. The module
is positioned at the top of the pilot valve body and below
the pilot valve yoke. Crucial valve components such as the
modulator, dome assembly, vent, and inlet seals never come
in contact with the dirty system media. The process media
pressure still controls the set pressure and blowdown of the
POSRV.
For applications requiring the main valve to relieve the dirty
fluid, an alternate clean media supply is piped to the pilot.
The alternate clean media must be set at the same pressure
as the set pressure of the pilot valve, but cannot exceed 3750
psig (258.55 barg), which is the design limit of the pilot valve.
In the event that the alternate clean media supply is lost, the
main valve will fail in the open position.
For applications requiring the main valve to relieve clean fluid
upstream of the dirty process in order to maintain the dirty
process pressure at safe levels, the dirty process pressure is
supplied to the dirty service module. The sensing line from
the main valve and the connection to the main valve dome
is connected to the pilot in the normal manner. The pilot is
set to operate at the design pressure of the dirty process.
When the dirty process pressure reaches the set to open
pressure of the pilot, the pilot is stroked by the increase in the
dirty process pressure and the pilot performs the block and
bleed operations to effect opening of the main valve. When
the dirty process pressure reaches the set to close pressure
of the pilot, the pilot is stroked by the reduction in the dirty
process pressure and the pilot performs the block and bleed
operations to bring about the closing of the main valve.
The dirty service module is a closed chamber. The flow of
dirty process media to the pilot valve is only that volume
required to stroke the pilot in response to increasing dirty
process pressure. The limited volume of flowing dirty media
entering the pilot makes plugging of the module an unlikely
possibility. However, if plugging of the module is a concern,
the module can be filled with a compatible clean liquid and a
siphon tube can be fitted in the connection line between the
pilot module and the dirty process.
The dirty service option can provide cost savings in material
selection for corrosive service. It is possible that only the
material of construction for the dirty service option will need
to be upgraded. The remaining parts in contact with clean
media can be of standard construction materials.
Note:
For special material options on the dirty service
option consult the factory.

3900 MPV Series Pilot Operated Safety Relief Valve Tech Spec | 65
Valve Installation
Valve Connections
The Consolidated 39MPV Series flanged valves are equipped
with ANSI B16.5 flanges. For other standards, contact the
factory.
connection to the vessel should be provided with a radius
to permit smooth flow to the valve. Sharp corners should be
avoided. Should this not be practical, then the inlet should be
swaged out at least one additional pipe diameter.
All flange drilling straddles the centerlines of the valve.
In any case, the pressure drop from the vessel to the valve
should not exceed 3 percent of set pressure when the valve
is flowing full capacity. In no event should the inlet piping be
smaller in diameter than the inlet connection of the valve.
Handling and Storage
Outlet Piping
Safety relief valves should be handled carefully. The internal
parts of a Pilot-Operated safety relief valve are precision
machined and fitted together to maintain perfect alignment.
Rough handling may damage the external tubing, pilot, and
main valve seats or may cause misalignment sufficient to incur
leakage or erratic operation. Safety relief valves are shipped
with a protective covering over the inlet and the outlet. This is
to prevent damage to the flanged surfaces and to prevent entry
of foreign material into the valve. If the valves are to be stored
before installation, the protective covering should be left intact
until installation. A clean, dry storage area is recommended.
Valves should always be protected with a suitable covering to
prevent entry of foreign material.
Alignment of the internal parts of a Pilot-Operated safety relief
valve is important to ensure proper operation. Although the
valve body will withstand a considerable mechanical load,
unsupported discharge piping should not impose loads any
higher than those stated in the Technical Information section
of this catalog, consisting of more than a companion flange,
long radius elbow and a short vertical pipe. Care should be
taken to ensure thermal expansion of piping and supports
does not produce strains on the valve. Spring supports are
recommended where necessary to avoid this condition.
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 discharge lines.
Inlet Piping
Consideration should be given to discharge pipe movement
resulting from wind loads. Any oscillation of the discharge
piping introduces stress distortion in the valve body, and the
resultant movement of the internal parts may cause leakage.
The facing on raised flanges is a spiral finish, 125 to 250 micro
inch roughness (Ra).
Pilot-operated safety relief valves must be installed in a vertical
upright position. The inlet piping to the valve should be short
and direct from the vessel or equipment being protected. The
