Introduction
The Type MR108 regulators are direct-operated,
backpressure, high-capacity, multi-purpose regulators.
They are designed to handle pressures up to 400 psig /
27.6 bar and temperatures up to 250°F / 121°C.
This product provides a fast, simple, reliable and
economical backpressure control in multi-purpose
applications suitable for different ow media including
liquid, air and gas. Applications include lube oil systems
and any application where speed of response is critical,
minimum differential pressure is a concern or uid
is not free of impurities. Type MR108 backpressure
regulators with low-pressure actuators can be set up to
35 psig / 2.4 bar and the high-pressure actuator version
can be set to 150 psig / 10.3 bar for constructions with
Fluorocarbon (FKM) diaphragm and 300 psig / 20.7 bar
for constructions with Nitrile (NBR) diaphragm.
The units are available in 4 sizes, NPS 1 through 4 /
DN 25 through 100 and are available in several
end connection congurations to meet demands on
application requirements.
Available with a quick-opening cage for quick speed
of response and high ow capacity. The cage-guided
metal plug provides superior control and stability.
The Type MR108 with Steel or Stainless steel body
construction has been designed to meet API 614 as
required by lube oil manufacturers.
Features
LargeFlow—Able to pass large ow rates with a
minimum pressure buildup.
Stability—The Type MR108 regulator’s cage-guided
metal plug design provides superior control stability of
delivery pressure.
FastResponse—Direct-operated for fast
response to meet the most demanding pressure and
ow requirements.
EasyDrain—Feature allows you to drain the
system without expensive spool pieces saving you
time and space.
EasyBleed—Feature allows you to purge the air
trapped underneath the diaphragm when the high-
pressure regulator is installed in the upright position,
which improves speed of response.

P1 = P2onHigh-PressureActuator—Inlet pressure
rating equals outlet pressure rating on high-pressure
actuator constructions up to 400 psig / 27.6 bar.
PrincipleofOperation
Refer to Figure 2. The Type MR108 is a multi-
purpose backpressure regulator. Upstream pressure
is registered externally through a 1/2 NPT control
line connection located at the low-pressure actuator
bonnet or high-pressure actuator lower casing. When
inlet pressure rises above the set pressure, the
pressure under the actuator diaphragm increases and
opens the regulator. This pressure overcomes the
regulator setting (which is set by the regulator control
spring). Through the action of the actuator stem, the
valve plug is pulled upward moving away from the seat
ring and allowing uid to escape through the cage into
the downstream system. When inlet pressure drops
back to set pressure, pressure under the actuator
diaphragm decreases. The control spring and the
valve spring forces push the actuator stem downward,
the valve plug moves closer to the seat ring and the
ow decreases downstream as the regulator closes
in response to the decreased pressure underneath
the diaphragm.

with actuator on the side, however, this could result in
premature wear of parts. Orientation of the two vents
should always be down. Vents may be rotated after
regulator installation to reposition so that the vent
screens are down.
A control line must be installed to allow inlet pressure
to register on the actuator’s diaphragm. The size of the
control line is indicated in the Specication sections
above and should be installed four to eight pipe
diameter before the backpressure regulator and in an
area of pipe that is free of turbulence.
An instruction manual is provided with every regulator
shipped. Refer to this for detailed installation,
operation, adjustment and maintenance instructions.
The instruction manual includes a complete listing of
individual parts and recommended spare parts.

1. Pressure ratings are based on a maximum operating temperature of 250°F / 121°C.
2. Maximum inlet, outlet and emergency pressures for constructions with Fluorocarbon (FKM) diaphragm are limited to 230 psig / 15.8 bar or the body rating limit, whichever is lower.
OverpressureCondition
Depending upon construction, backpressure control
ratings are from 5 to 300 psig / 0.34 to 20.7 bar.
The maximum inlet pressure can be found in
Table 5. System operation within these limitations
does not eliminate the possibility of damage from
external sources or from debris in the ow line. The
backpressure regulator should be inspected for damage
regularly and after any overpressure condition.
Installation
Note
Notallcodesorregulationswill

overpressureprotectiondevices.
Vertical installation with the actuator installed directly
above or below the main valve is recommended but for
optimal performance the actuator should be installed
below the main valve. The use of a bleed valve is
recommended for liquid installations that require the
high pressure actuator to be mounted above the main
valve. The unit will operate in horizontal installations

• Auxiliary pump (Pump 2) and lter system is brought
into operation while main pump is in operation.
• Auxiliary pump ramp up rate is one second.
• Auxiliary pump produces a pressure spike
that is beyond the limitations of the pressure
reducing regulator.
• The backpressure regulator relieves the excess
pressure back to the oil tank. Flow rate is 120% of
total pump rate.
Main pump can now be shut down to allow repair of
the system. High capacity direct-operated regulators
are recommended for this type of application where
speed of response is critical. The Type MR108 can
provide fast response to the pressure spikes as
described above while maintaining a constant delivery
pressure of oil to the bearing.
UniversalNACECompliance
Optional materials are available for applications
handling sour gases. These constructions comply with
the recommendations of NACE International Sour
Service Standards.
The manufacturing processes and materials used
by Regulator Technologies assure that all products
specied for sour gas service comply with the
chemical, physical and metallurgical requirements of
NACE MR0175 and/or NACE MR0103. Customers
have the responsibility to specify correct materials.
Environmental limitations may apply and shall be
determined by the user.
Figure 3. Lube Oil Skid Diagram
LubeOilSkids(Figure3)
Lube oil skids maintain oil ow to bearings, seals and
servo-controls on critical turbomachinery assets such
as air and gas compressors, steam turbines, power
recovery turbines and power generating equipment.
These skids are essential in keeping lube oil clean
at all times and ensure maximum service life for the
equipment. Because it is critical to maintain a constant
ow and pressure of oil to the equipment, it is normally
equipped with two pumps – the main pump and the
auxiliary pump, which will take over in case of main
pump failure – and lters.
In normal condition, the skids operate in the
following manner:
• Lube oil is stored in the tank at atmospheric pressure.
• It is then fed to the main pump (Pump 1) which
pressurizes the lube oil.
• Oil then goes through a lter.
• After ltration, oil ow is split such that a fraction is
sent to a backpressure regulator to limit the supply
pressure to the pressure reducing regulator. 20%
of the pump rate ows through the backpressure
regulator, sending back oil to the oil tank.
• The pressure reducing regulator decreases the
pressure to a safe and allowable range. Flow
through this regulator is 80% of pump rate.
• Oil ows to large rotating equipment lubricating
bearings, e.g. turbines and compressors.
The loss of pressure or ow to the bearings or these
turbomachinery assets may shut down the equipment
or even the whole plant. Failure of the main pump or
lter results in the following upset operation:
