Introduction

Scope of the Manual

This manual provides instructions for the installation,

adjustment, maintenance and parts ordering for

MR95 Series pressure regulators. These regulators

are usually shipped separately for line or panel

mounting or installed on other equipment. Instructions

and parts lists for other equipment are found in

separate manuals.

Product Description

MR95 Series regulators are suitable for steam, air,

gas, water, oil and similar uids. Types MR95L,

MR95H, MR95HP and MR95HT are direct-operated

pressure reducing regulators for pressure control

requiring constant outlet pressures between

2 and 400 psig / 0.14 and 27.6 bar. Types MR95LD

and MR95HD are small-size, large-capacity,

differential pressure regulators. The differential

pressure range is from 2 to 150 psi / 0.14 to 10.3 bar.

Typical MR95 Series regulators are shown in Figure 1.

Pressure Reducing Regulators

Type MR95L—Pressure reducing regulator suitable

for controlling many gases and liquids. Gray Cast Iron,

Steel, Stainless steel, Hastelloy® C and Monel® bodies

are available. Outlet pressure range is from 2 to

30 psig / 0.14 to 2.1 bar with three different springs

available. Body sizes are available from 1/4 NPT and

1/2 through 1 in. / DN 15 through 25 with a variety

of end connections. The standard orice sizes are

0.284, 0.416 and 0.631 in. / 7.22, 10.56 and 16.02 mm

diameter, dependent on body sizes.

Type MR95H—Basically the same as Type MR95L,

but permits higher outlet pressure ranges from

15 to 150 psig / 1.0 to 10.3 bar for the 1/4 NPT and

1/2, 3/4 and 1 in. / DN 15, 20 and 25 sizes. Also

available in 1-1/2 and 2 in. / DN 40 and 50 sizes with a

1.142 in. / 29 mm orice to give outlet pressure ranges

from 5 to 150 psig / 0.34 to 10.3 bar.

Type MR95HP—Basically the same as Type MR95H,

but permits even higher outlet pressure ranges from

15 to 400 psig / 1.0 to 27.6 bar.

Type MR95HT—Basically the same as Type MR95H,

but permits higher outlet pressures at higher

temperatures. Outlet pressure ranges are available

from 15 to 300 psig / 1.0 to 20.7 bar and temperatures

up to 650°F / 343°C.

Differential Pressure Regulators

Type MR95LD—Small-size, large-capacity, differential

pressure regulators. Typical applications include use

on testing xtures, wash tanks, sterilizers, steam

tables, fuel lines and plant air supplies. Gray Cast

Iron, Steel, Stainless steel, Hastelloy® C and Monel®

bodies are available. Differential pressure range is

from 2 to 30 psi / 0.14 to 2.1 bar with three different

spring ranges.

Type MR95HD—Basically the same as Type MR95LD,

but permits higher differential pressure ranges from

5 to 150 psi / 0.34 to 10.3 bar with seven different

spring ranges.

Principle of Operation

For Types MR95H, MR95L,

MR95HP and MR95HT

Pressure Reducing Regulators

Types MR95L, MR95H, MR95HP and MR95HT

(see Figure 2) are direct-operated regulators

and use spring force to regulate outlet pressure.

Downstream pressure is registered either internally

through the body or externally through a control

line to the under side of the diaphragm. When the

downstream pressure is at or above the set pressure,

the disk is held against the orice and restricting

ow through the regulator. When demand increases,

downstream pressure drops slightly allowing the spring

to extend, moving the stem down and the disk away

from the orice. This allows uid ow through the body

to the downstream system.

For Types MR95LD and MR95HD

Differential Pressure Regulators

Types MR95LD and MR95HD regulators maintain

a differential pressure between the loading supply

pressure and the downstream pressure of the regulator.

See Figure 2. The design of the regulator isolates the

diaphragm and pressure response chamber from the

main ow stream. The downstream pressure (outlet

pressure) is registered under the diaphragm through

the pitot tube or registration hole. If the downstream

pressure increases, pressure under the diaphragm

also increases. This force overcomes the spring

compression and loading supply pressure, allowing

the stem to rise. The valve plug spring forces the valve

plug closer to the orice. Flow through the regulator

is reduced so that downstream pressure returns to

the desired differential level. When the downstream

pressure decreases, the opposite action takes place.

Pressure under the diaphragm decreases. The valve

stem pushes the valve plug downward, opening the

ow stream and increasing the uid ow through the

regulator. Downstream pressure rises back to the

desired differential level.

Figure 3. Differential Pressure Regulator Installation Schematics

Installation

WARNING

!

Personal injury or system damage

may result if this regulator is installed,

without appropriate overpressure

protection, where service conditions

could exceed the limits given in the

Speci cations section and/or regulator

nameplate. Refer to Overpressure

Protection section for recommendations

on how to prevent service conditions

from exceeding those limits.

Additionally, physical damage to the

regulator may result in personal injury

or property damage due to escaping of

accumulated gas. To avoid such injury

and damage, install the regulator in a

safe location.

Under enclosed conditions or indoors,

escaping gas may accumulate and be an

explosion hazard. In this case, the vent

should be piped outdoors.

For regulator constructions with a

spring case vent, the vent should be

kept open to permit free  ow of gas

to the atmosphere. Protect openings

against entrance of rain, snow, insects

or any other foreign material that may

plug the spring case vent or vent line.

Before installing the regulator:

• Unpack the regulator and remove the protective

shipping plugs from the end connections of

the body and the pressure connection in the

spring case.

• Check the regulator and make sure it has not

been damaged or collected foreign material

during shipping.

• Remove any debris or dirt in the tubing and

the pipeline.

• Apply pipe compound to the external pipe thread

for NPT bodies or use appropriate gaskets for

 anged bodies.

• Make sure gas  ow through the regulator is in the

same direction as the arrow on the body.

On 1-1/2 or 2 in. / DN 40 or 50 Types MR95H, MR95HP

and MR95HT regulators, the spring case vent is tapped

so a vent line can be connected to provide venting to a

remote location. On 1/4 NPT, 1/2, 3/4 and 1 in. / DN 15,

20 and 25 Types MR95H, MR95HP and MR95HT body

sizes, the tapped vent option is available on request.

Protect the exposed end of the vent pipe with a weather

and insect resistant vent assembly. Periodically check

all vents and remote vent lines to ensure that they

are unobstructed.

On Types MR95LD and MR95HD regulators, the

loading pressure is connected to the 1/4 NPT

connection in the spring case.

Overpressure Protection

WARNING

!

Personal injury, equipment damage or

leakage due to escaping accumulated gas

or bursting of pressure-containing parts

may result if this regulator is:

• Overpressured

• Installed where service conditions

could exceed the limits given in the

Specications section and on the

appropriate nameplate

• Where conditions exceed any ratings of

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.

The Types MR95H and MR95HD regulators have an

outlet pressure rating equal to the inlet pressure rating.

The Types MR95L, MR95LD, MR95HP and MR95HT

regulators have an outlet pressure rating lower than

the inlet pressure rating.

The recommended pressure limitations are

stamped on the regulator nameplate. Some type of

overpressure protection is needed if the actual inlet

pressure exceeds the maximum operating outlet

pressure rating. Provide external overpressure

protection if the regulator inlet pressure is greater than

the safe working pressure of downstream equipment.

Common methods of external overpressure protection

include relief valves, monitoring regulators, shutoff

devices and series regulation.

Regulator operation below the maximum pressure

limitations does not preclude the possibility of damage

from external sources or from debris in the pipeline. If

the regulator is exposed to an overpressure condition,

inspect it for any damage that may have occurred.

Startup

Note

The Specications section and Tables 3

and 4 show the maximum inlet, the

differential and the outlet pressures for

specic constructions. Use pressure

gauges to monitor inlet pressure, outlet

pressure and any loading pressure

during startup.

1. Check that proper installation is completed

and downstream equipment has been

properly adjusted.

2. Make sure all block and vent valves are closed.

3. Decompress the control spring by turning the

adjusting screw (for Types MR95L, MR95H,

MR95HP and MR95HT) or handwheel (for

Types MR95LD and MR95HD) counterclockwise.

4. Slowly open the valves in the following order:

a. Loading supply and control line valve(s), if used

b. Inlet block valve

c. Outlet block valve

5. Set the regulator to the desired outlet (control)

pressure according to the Adjustment procedure.

Adjustment

WARNING

!

To avoid personal injury, property

damage or equipment damage caused

by bursting of pressure containing parts

or explosion of accumulated gas, never

adjust the control spring to produce an

outlet pressure higher than the upper

limit of the outlet pressure range for that

particular spring. If the desired outlet

pressure is not within the range of the

control spring, install a spring of the

proper range.

The factory setting of the regulator can be varied

within the pressure range stamped on the nameplate.

Follow the following procedures for the proper

adjustment of the outlet (control) spring. If the spring

range was changed, be sure to change the stamped

spring range on the nameplate.

All MR95 Series regulator springs can be backed off

to provide zero outlet. Recommended outlet pressure

ranges available, maximum inlet pressures and color

codes of the respective springs are shown in Tables 3

and 4.

MR95 Series

Types MR95L, MR95H, MR95HP

and MR95HT

Key numbers are referenced in Figure 6, 8 or 9.

1. Loosen the jam nut (key 17).

2. Turn the adjusting screw (key 15) clockwise to

increase outlet pressure or counterclockwise to

decrease it.

3. Monitor the outlet pressure with a test gauge

during the adjustment.

4. Tighten the jam nut (key 17) to maintain the

desired setting.

Types MR95LD and MR95HD

Key numbers are referenced in Figure 7 or 10.

1. Turn handwheel (key 38) clockwise to increase

outlet pressure or counterclockwise to decrease it.

2. Monitor the outlet pressure with a test gauge

during the adjustment.

Shutdown

1. Close the upstream block valve to the regulator inlet.

2. Close the downstream block valve to the

regulator outlet.

3. Vent the downstream pressure by slowly opening

the bleed valve between the regulator and the

downstream shutoff valve. Without changing

regulator spring adjustment, all pressure between

the upstream and downstream shutoff valves

will be released through the bleed valve, since

the Type MR95L, MR95H, MR95HP or MR95HT

regulator opens in response to the decreased outlet

pressure. For Types MR95L, MR95H, MR95HP

and MR95HT regulators, skip steps 4, 5 and 6. For

Types MR95LD and MR95HD continue steps 4

through 6.

4. Close the block valve to the loading pressure.

5. Vent loading pressure slowly to release pressure

in the spring case.

6. Vent inlet pressure slowly (through the bleed

valve) to release all remaining pressure in

the regulator.

Maintenance

WARNING

!

To avoid personal injury, property damage

or equipment damage caused by sudden

release of pressure or explosion of

accumulated gas, do not attempt any

maintenance or disassembly without

rst isolating the regulator from system

pressure and relieving all internal

pressure from the regulator.

To avoid possible personal injury from

spring or pressure-loaded actuator, make

certain the adjusting screw is completely

backed off and the spring case pressure

is vented prior to disassembly. Otherwise,

the spring load or loading pressure could

forcefully eject the spring case.

Regulators that have been disassembled

for repair must be tested for proper

operation before being returned to

service. Only parts manufactured by

Emerson™ should be used for repairing

Fisher® regulators.

Due to normal wear or damage that may

occur from external sources, this regulator

should be inspected and maintained

periodically. The frequency of inspection

and replacement of parts depends upon

the severity of service conditions or the

requirement of local, state and federal

rules and regulations.

Due to normal wear that may occur, inspect the

parts periodically and replace if necessary. The

frequency of inspection depends on the severity of

service conditions or the requirements of state and

federal laws.

Replace parts such as the O-rings, gaskets, diaphragm

and packing as necessary. Always apply lubricants as

the regulator is being reassembled. Suitable lubricants

are shown in the assembly drawings.

The regulator does not have to be taken out of the

pipeline to be disassembled. All key numbers are

referenced in Figures 4 to 10.

Replacement or Maintenance of Orice

and Valve Plug

If it appears that the valve does not shut off tightly, the

orice and valve plug could be worn out or damaged.

Proceed as follows to check and/or replace them.

1. Shut down the regulator. Refer to Shutdown section

for the proper procedure.

2. Unscrew the valve plug guide (key 5) from the

body (key 1). The valve plug spring (key 26) and

the valve plug (key 4) will normally come out of the

body along with the valve plug guide. On 1-1/2 or

2 in. / DN 40 or 50 body size regulators, the stem

(key 6) will also come out of the regulator body.

3. Inspect the seating surface of the valve plug (key 4),

make sure that the elastomer, PTFE or polished

metal surface of the valve plug is not damaged. Also

inspect the external O-ring (key 4c) on the valve

plug of Type MR95HP. Replace the valve plug

assembly if damage is noted.

4. Inspect the seating edge of the orice (key 3).

If damage is noted, unscrew the orice from

the body (key 1) and replace it with a new part.

Reference Table 8 for proper torque values.

5. Reassemble the regulator in the reverse order of

the above steps. When installing the valve plug

guide (key 5), coat the threads and sealing surface

with sealant to ensure an adequate metal-to-metal

seal. Reference Table 8 for proper torque values.

Flange Cap Screw Torque Inspection

Retorquing of spring case cap screws may be

necessary for some MR95 Series regulators after a

period of use. Retorque the cap screws as follows:

1. Shut down the regulator. Refer to Shutdown

section for the proper procedure.

2. Retighten the cap screws (key 16) in a crisscross

pattern. See Table 8 for proper torque values.

3. Follow the Startup section to repressurize

the regulator.

4. Refer to the Replacement of Diaphragm section

as needed.

Replacement of Diaphragm

When the regulator does not respond to differential or

downstream pressure changes, if uid leaks or vents

to the spring case (pressure reducing regulators) or

the loading pressure seems to leak to the downstream

piping (differential pressure regulators), the diaphragm

could be worn out or ruptured. Inspect/replace the

diaphragm as follows:

CAUTION

Metal diaphragms have thin sharp

edges. To avoid hand cuts, be careful

when handling the diaphragm and

particularly the diaphragm edge.

1. Shut down the regulator. Refer to “Shutdown”

section for the proper procedure.

2. For Types MR95L, MR95H, MR95HP and

MR95HT—loosen the jam nut (key 17) and turn

the adjusting screw (key 15) counterclockwise to

remove all spring compression.

For Types MR95LD and MR95HD—turn the

handwheel (key 38) counterclockwise to remove

all spring compression.

CAUTION

Provide adequate support to the spring

case when disassembling MR95 Series

regulator installed in a vertical

installation or other application where

the spring case is not oriented upward.

Without adequate support, the spring

case may fall and cause physical injury

when the cap screws are loosened.

3. Remove the cap screws (key 16) from the

diaphragm casing. Lift the entire spring case

(key 2) off of the body (key 1).

4. Remove the upper spring seat (key 9) and

regulator spring (key 11). For Types MR95H,

MR95HP and MR95HT with body sizes 1-1/2 and

2 in. / DN 40 and 50 skip steps 5 and 6.

5. For Type MR95HD and 1/4 NPT to 1 in. /

DN 25 body sizes of Types MR95H, MR95HP

and MR95HT—remove the lower spring seat (key 8).

For Types MR95L and MR95LD—remove the

diaphragm head assembly (key 21, lower spring

seat and diaphragm head threaded together).

6. Remove the diaphragm(s) (key 12) and examine

for damage. Replace if damage is noted. See

Table 7 for the required number of diaphragm(s).

Proceed to step 9.

7. For body sizes 1-1/2 and 2 in. / DN 40 and 50,

remove the diaphragm and diaphragm head. The

diaphragm head can only be disassembled for the

1. Reduce spring case bolt’s torque by 30% when using Ethylenepropylene (EPDM) diaphragms.

10. If the unit has metal diaphragms (see Figures 4

and 5):

a. (Applicable only for the lower diaphragm head

of Types MR95H, MR95HT and MR95HD, 1-1/2

and 2 in. / DN 40 and 50.) Find the pusher

post (key 10) and place on a surface with the

larger at surface down and the thread stem up

(metal diaphragm pusher post has a recessed

diameter in the bottom surface). Then, nd

one smaller composition gasket (key 29) and

t it over the threaded end of the pusher post.

Find and take one of the diaphragm heads and

slip it over the threaded end of the pusher post

with the chamfered side of the diaphragm head

toward the gasket. Take a second gasket and

place it over the threaded end of the pusher

post on top of the diaphragm head.

b. Replace one of the two large diaphragm gaskets

(key 19) on the surface of the body (key 1) that

will support the diaphragms (key 12). There will

be two diaphragms used per regulator, except

for Types MR95L and MR95LD, 1/4 NPT with

2 to 6 psi / 0.14 to 0.41 bar spring range setting

which use only one metal diaphragm (the

metal diaphragm is in between two diaphragm

gaskets). Another diaphragm gasket will be

placed on top of the second metal diaphragm.

The raised surfaces of the metal diaphragms

should be placed in the unit so that they are

facing toward the assembler (toward the spring)

except only when one metal diaphragm is

being used then the raised surface should be

facing down (towards the body). See Figure 2

as reference.

11. Reassemble in the reverse of the above

procedures. Lubricate the upper spring seat

(key 9) and the exposed threads of the adjusting

screw (key 15) with anti-seize lubricant. Install the

cap screws (key 16) in a crisscross pattern and

tighten to nger tight only.

12. To ensure proper slack in the diaphragm, install

the adjusting screw (key 15, for Types MR95L,

MR95H, MR95HP and MR95HT) or handwheel

(key 38, Types MR95LD and MR95HD), if

completely removed and turn it clockwise. This
