Introduction

The MR95 Series regulators are compact, large-capacity,

direct-operated pressure regulators (see Figure 1). The units

are available in 1/4 NPT through 2 in. / DN 50 sizes and are

offered in several different end connection congurations.

They are designed to handle pressures up to 1000 psig /

68.9 bar and temperatures up to 650°F / 343°C.

These products can help solve the toughest pressure control

applications. Typical applications include superheated steam,

steam injection, steam tracing, nitrogen purging, boiler feed

water, process chemicals, cooling water, test xtures, wash

tanks, sterilizers/autoclaves, fuel lines, pneumatic supply and

many others.

Features

• Handwheels/Tee Handles—Allow easy pressure

setting changes and are standard on Types MR95LD

and MR95HD, and optional on the Types MR95L,

MR95H, MR95HP and MR95HT regulators.

• Versatile—Can be used with all process media

including air, steam, gas, water, liquids (oils and

process chemicals) and oxygen.

• Tight Shutoff With Elastomer Seats—Metal seats

available for high temperatures.

• Direct-Operated—Design maximizes speed

of response.

• Robust—Up to 1000 psig / 68.9 bar inlet pressure.

• P1 = P2—Inlet equals outlet rating in Types MR95H and

MR95HD up to 300 psig / 20.7 bar.

• Rugged Construction—Available in a variety of body

and spring case materials to address the toughest service

conditions. Severe service elastomers and corrosion

resistant trims are also available and provide excellent

uid compatibility.

• Differential Pressure Capability—Spring-loaded

Polytetrauoroethylene (PTFE) packing and

tapped connections permit pressure loading of the

Types MR95LD and MR95HD spring cases.

• Special Service Capabilities—Optional materials

are available for applications handling sour gases,

cryogenics and superheated steam.

• Large Turndown Ratio—No need for low Cv trims at

low ows.

• Graphite Gaskets—For high temperature applications

up to 650°F / 343°C (optional).

• Set Pressures up to 400 psig / 27.6 bar

• Multiple End Connection Options—To match

your application.

• Easy Maintenance—Seating parts are easily accessible

by removing the plug on the bottom of the regulator.

• API 614 Compliant—Steel and Stainless steel

constructions meet API 614 requirements.

Principle of Operation

The MR95 Series (refer to Figure 2) is a direct-operated

regulator. Downstream pressure is registered internally

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,

restricting uid 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. Types MR95H, MR95L, MR95HP

and MR95HT use spring force to regulate outlet pressure.

Types MR95HD and MR95LD use spring force to maintain

a differential pressure between spring case loading

pressure and outlet pressure.

1. For Types MR95LD and MR95HD regulators, the pressure ranges indicate the differential pressure that can be obtained with the indicated spring. The differential pressure

(spring setting) is added to the spring case loading pressure to determine the actual outlet pressure.

2. Springs meet NACE MR0175-2002 and NACE MR0103 requirements only for applications in which the spring is not exposed to the sour gas.

4. Use the following formula to determine the interpolated

capacity (Q):

Qb - Qa Qb - Q

P2b - P2a P2b - P2

=

Example:

P1 = 100 psig / 6.9 bar

1/4 NPT Type MR95H with 15 to 30 psig / 1.0 to 2.1 bar

spring range

P2 = 20 psig / 1.4 bar

Determine air capacity, Q

Solution:

Qa = 1100 SCFH / 28.8 Nm3/h

P2a = 15 psig / 1.0 bar

Qb = 1700 SCFH / 46.5 Nm3/h

P2b = 30 psig / 2.1 bar

1700 - 1100 1700 - Q

30 - 15 30 - 20

=

Q = 1300 SCFH

46.5 - 28.8 46.5 - Q

2.1 - 1.0 2.1 - 1.4

Q = 35 Nm3/h

=

Note

The same interpolation procedure can be

used for different inlet pressures.

Contact your local Sales Ofce if you should have any

questions about selecting the proper regulator.

Air Capacities

Regulating capacities at selected pressures and outlet

pressure ows are given in SCFH (60°F and 14.7 psia)

of air. To determine the equivalent capacities for other gases,

multiply the table capacities by the following appropriate

conversion factors: 1.29 for 0.6 specic gravity natural gas,

0.808 for propane, 0.707 for butane or 1.018 for nitrogen.

For gases of other specic gravities, divide by the square root

of the appropriate specic gravity.

Then, if capacity is desired in Nm3/h at 0°C and 1.01325 bar,

multiply SCFH by 0.0268.

Capacities in Tables 10, 11, 12, 13 and 14 are for regulators

using elastomer diaphragms. Depending on regulator

construction, a multiplier must be used to convert to capacities

for regulators using metal diaphragms.

Installation

The MR95 Series regulators may be installed in any

position, as long as ow will be in the same direction as that

indicated by the body arrow. The Types MR95H, MR95L,

MR95HT and MR95HP regulators should be installed so

that their spring case vents are protected from anything that

might clog them.

Emerson Process Management Regulator Technologies, Inc.

(Emerson™) provides an instruction manual with every regulator

shipped. Refer to this for complete installation, operation and

maintenance instructions. Included is a complete list of individual

parts and recommended spare parts.

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

Emerson assure that all products specied for sour gas

service comply with the chemical, physical and metallurgical

requirements of NACE MR0175 ISO-2002 and/or

NACE MR0103. Optional materials are available to meet

ANSI/NACE MR0175/ISO 15156, please contact your local

Sales Ofce for special ordering instructions. Customers have

the responsibility to specify correct materials. Environmental

limitations may apply and shall be determined by the user.

Capacity Data

The capacity information on the following pages is based on

three droop factors, 10%, 20% and 40%. Droop is deviation

from the setpoint of the regulator, and is usually stated in

percentage of setpoint value.

For highest capacity and the most accurate control within a

particular type of the MR95 Series regulators, use the lowest

range spring that can be adjusted to the desired setpoint

(see Table 3 for part numbers of appropriate springs for

each body size).

If closer control is necessary, a regulator of larger capacity

or different design should be selected, so that the necessary

ow can be obtained with a smaller droop factor.

Sometimes it may be necessary to interpolate the capacity

table data to determine capacity for outlet settings not given.

To maintain accuracy, it is important when interpolating to

stay within a spring range if possible. The following is a

procedure for interpolating the data to calculate ow:

1. Determine which spring is to be used.

2. Find the two outlet settings (P2a and P2b) that bracket

the actual outlet pressure P2.

3. For a given body size and inlet pressure, nd the

capacity Qa for P2a and Qb for P2b.

To determine wide-open ow capacity for relief valve sizing of air

at a temperature of 60°F, use the equation for critical pressure

drops (absolute outlet pressure equal to one-half or less than

one-half the absolute inlet pressure).

Q = P1(abs)Cg

where,

Q = Gas ow, SCFH (60°F and 14.7 psia)

P1(abs) = Absolute inlet pressure, psia (add 14.7 psi

to gauge inlet pressure to obtain absolute

inlet pressure)

C g

= Wide-open gas sizing coefcient from

Table 5

For pressure drops lower than critical (absolute outlet

pressure greater than one-half the absolute inlet pressure),

use the sizing nomographs in Fisher® Catalog 10, or the

Fisher Sizing Program.

To obtain capacities in Nm3/h at 0°C and 1.01325 bar,

multiply the capacity determined in SCFH by 0.0268.

Steam Capacities

Capacities in Tables 15, 16, 17, 18 and 19 are in lbs/h

of saturated steam. To obtain capacities in kg/h, multiply

the capacities given in the table by 0.4535. Capacities

have been calculated for stainless steel diaphragms only

since steam service exceeds the elastomer diaphragm

temperature limits.

To determine wide-open ow capacity for relief valve sizing

of steam, use the equation for critical pressure drops

(absolute outlet pressure equal to one-half or less than one-

half absolute inlet pressure).

Q = P1(abs)Cs

where,

Q = Steam ow, lbs/h

P1(abs) = Absolute inlet pressure, psia (add 14.7 psi

to gauge inlet pressure to obtain absolute

inlet pressure)

C s = Wide-open steam sizing coefcient from

1. To obtain capacities for Type MR95HT (metal diaphragm), multiply the table values by 0.6.

2. To obtain capacities for regulators with reduced ow orices, multiply the table values by 0.7.

For pressure drops lower than critical (absolute outlet

pressure greater than one-half absolute inlet pressure),

use the sizing nomographs in the Fisher® Sizing Program.

Water Capacities

All water capacities in Tables 20, 21, 22, 23 and 24 are in

gallons per minute (GPM). Capacities in Tables 20, 21 and

23 are for regulators using only elastomer diaphragms.

Depending on regulator size, a multiplier, given in these

tables, must be used to convert to capacities for regulators

using metal diaphragms.

To determine ow capacity for liquid relief valve sizing, refer

to the Fisher Sizing Program using the Cv coefcients given

in Table 5. The Km values listed in Table 5 can be used to

predict choked ow on liquid service.

To convert capacities to m3/h, multiply GPM by 0.2271.
