Introduction

The 95 Series regulators are compact, large-capacity,

direct-operated pressure regulators (see Figures 1 and 2).

The units are available in NPS 1/4 through 2 (DN 15

through 50) sizes and are offered in several different

end connection congurations. They are designed

to handle pressures up to 600 psig (41,4 bar) and

temperatures up to 650°F (343°C).

This product 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—Allow easy pressure setting changes

and are standard on Types 95LD, 95HD, and optional

on the NPS 1/2 (DN 15) body size of the Types 95L

and 95H regulators. Tee-handles are optional on all

other Types 95L and 95H body sizes.

• 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 600 psig (41,4 bar) inlet pressure.

• P1 = P2—Inlet equals outlet rating in 95H Series up

to 600 psig (41,4 bar).

• Rugged Construction—Available in a variety of

materials including Cast iron, Carbon steel, Stainless

steel, Monel®, Hastelloy® C, Peruoroelastomer

(FFKM), and Fluorocarbon (FKM) to address the

toughest service conditions. Severe service

elastomers and corrosion resistant trims are also

available - excellent uid compatibility.

• Differential Pressure Capability—Spring-loaded

Polytetrauoroethylene (PTFE) packing and tapped

connections permit pressure loading of the

Types 95LD and 95HD spring cases.

• Special Service Capabilities—Optional materials

are available for applications handling sour gases,

cryogenics, and superheated steam. These

constructions comply with the recommendations

of NACE International Standards MR0175

and MR0103.

• 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 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.

Principle of Operation

The 95 Series (refer to Figure 2) is a direct-operated

regulator. Downstream pressure is registered

internally through the body 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 there is no 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

ow through the body to the downstream system.

Types 95H, 95L, 95HP, and 95HT use spring force to

regulate outlet pressure. Types 95HD and 95LD use

spring force to maintain a differential pressure between

spring case loading pressure and outlet pressure.

Installation

The 95 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 95H, 95L,

95HT, and 95HP regulators should be installed so that

their spring case vents are protected from anything that

might clog them.

Emerson™ provides an instruction manual with

every regulator shipped. Refer to this for complete

installation, operation, and maintenance instructions.

Included is a complete listing of individual parts and

recommended spare parts.

Table 1. Sizing Types 95HD and 95LD Pressure Regulators

STEPS EXAMPLE - PSIG EXAMPLE - bar

1. Determine service conditions.

P1 = 135 psig, P2 = 25 to 40 psig,

Bias = 10 psig

Loading pressure = 15 to 30 psig

Qmax = 1100 SCFH air

Specic Gravity = 1

Allowable droop = 20%

Line size = 1/2-inch

P1 = 9,31 bar, P2 = 1,7 to 2,8 bar,

Bias = 0,69 bar

Loading pressure = 1,0 to 2,1 bar

Qmax = 29,5 Nm3/h air

Specic Gravity = 1

Allowable droop = 20%

Line size = 13 mm

2. Select type number and spring range

using Tables 3 and 5.

Since the bias set is 10 psig, select the Type 95LD

with a 5 to 15 psig spring range. (The Type 95LD

will withstand the pressure for the application, and

also has the lightest spring available.)

Since the bias set is 0,69 bar, select the Type 95LD

with a 0,34 to 1,0 bar spring range. (The Type 95LD

will withstand the pressure for the application, and also

has the lightest spring available.)

3. Using the Fisher® Sizing Program,

calculate Cg from data given in the

capacity tables. Use the table inlet

pressure closest to the service condition.

Also calculate using the table outlet

pressure which is closest to the

spring bias.

For the purpose of sizing, use the spring setpoint

(bias) of 10 psi as outlet pressure, and an inlet

pressure of 150 psig.

The closest capacity data in Tables 4 and 8

shows the following:

C1 = 35 (Table 4)

P1table = 150 psig

P2table = 10 psi

Droop = 10 psig x 20% = 2 psig

∆Ptable = 150 psig - (10 psig - 2 psig) = 142 psid

Q = 1400 SCFH for size NPS 1/2 Type 95LD at

20% droop

For the purpose of sizing, use the spring setpoint

(bias) of 0,69 bar as outlet pressure, and an inlet

pressure of 10,3 bar.

The closest capacity data in Tables 4 and 8 shows

the following:

C1 = 35 (Table 4)

P1table = 10,3 bar

P2table = 0,69 bar

Droop = 0,69 bar x 20% = 0,14 bar

∆Ptable = 10,3 bar - (0,69 bar - 0,14 bar) = 9,8 bar d

Q = 37,5 Nm3/h for size DN 15 Type 95LD at

20% droop

4. Use the information in Step 3 to calculate

Cg using the Fisher Sizing Program. Cg calculated = 8.5 Cg calculated = 8.5

5. Calculate ow for application based upon

actual conditions and calculated Cg.

P1 = 135 psig

P2max = 40 psi

Droop = 10 psig x 20% = 2 psig

∆P actual = 135 psig - (40 psig - 2 psig) = 97 psid

Cg calculated = 8.5

Q = 1248 SCFH air with droop equal to

20% of spring bias

P1 = 9,3 bar

P2max = 2,8 bar

Droop = 0,69 bar x 20% = 0,14 bar

∆P actual = 9,3 bar - (2,8 bar - 0,14 bar) = 6,7 bar d

Cg calculated = 8.5

Q = 33,4 Nm3/h air with droop equal to

20% of spring bias

Table 2. Back Calculating Sizing Coefcients

STEPS EXAMPLE - PSIG EXAMPLE - bar

1. Determine service conditions. P1 = 25 psig, P2 = 18 psig, Qmax = 10 GPM,

Medium = Water

P1 = 1,7 bar, P2 = 1,2 bar,

Medium = Water, Qmax = 37,8 l/min

2. Select Type number and spring range

using Tables 3 and 5.

The Type 95L with a 13 to 30 psig pressure range,

will provide the lightest spring for the application.

The Type 95L with a 0,90 to 2,1 bar pressure range,

will provide the lightest spring for the application.

3. Because the capacity table for a Type 95L

in Table 18 does not provide data for the

exact application, choose the values from

the table that most closely match the

application. An NPS 1 (DN 25) Type 95L

ts the closest.

P1table = 30 psig

P2table = 20 psig

Droop = 20 psig x 20% = 4 psig

∆Ptable = 30 psig - (20 psig - 4 psig) = 14 psid

Q = 13 GPM

Km = 0.67 (See Table 4)

P1table = 2,1 bar

P2table = 1,4 bar

Droop = 1,4 bar x 20% = 0,28 bar

∆Ptable = 2,1 bar - (1,4 bar - 0,28 bar) = 0,97 bar d

Q = 49,2 l/min

Km = 0.67 (See Table 4)

4. Use information in Step 3 to calculate Cv

using Fisher® Sizing Program. Cv calculated = 3.47 Cv calculated = 3.41

5. Determine ow capacity of Type 95 with

actual conditions using Cv calculated from

Step 4.

Cv = 3.47

P1 = 25 psig

P2 = 18 psig

Droop = 18 psig x 20% = 3.6 psig

∆P actual = 25 psig - (18 psig - 3.6 psig) = 10.6 psid

Q calculated = 11.3 GPM

Cv = 3.41

P1 = 1,7 bar

P2 = 1,2 bar

Droop = 1,2 bar x 20% = 0,25 bar

∆P actual = 1,7 bar - (1,2 bar - 0,25 bar) = 0,73 bar d

Q calculated = 42,8 l/min

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

and/or NACE MR0103. 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 example, refer to the air ow rate curve in

Figure 3. The regulator is set for 15 psig (1,0 bar)

at the outlet, with 100 psig (6,9 bar) at the inlet and a

300 SCFH (8,0 Nm3/h) ow rate. Capacity at 10%

droop is read at the intersection of a line projected

horizontally to the right from the 13.5 psig (0,93 bar)

outlet pressure point and the 100 psig (6,9 bar) inlet

curve. The 13.5 psig (0,93 bar) is derived by applying

the droop factor of 10% to the regulator setting of

15 psig (1,0 bar). The same method is employed for

20% droop, except the capacity value is read at the

12 psig (0,83 bar) outlet pressure point, 20% less than

the 15 psig (1,0 bar) setting.

For highest capacity and the most accurate control

within a particular type of the 95 Series regulators,

use the lowest range spring that can be adjusted

to the desired setpoint (see Table 5 for part numbers

of appropriate springs for each body size). See

Table 1 for sizing example for the Types 95HD and

95LD regulators.

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.

Bulletin 71.1:95

11

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

1,10325 bar, multiply SCFH by 0.0268.

Capacities in Tables 8, 9, 10, and 11 are for regulators

using elastomer diaphragms. Depending on regulator

construction, a multiplier must be used to convert to

capacities for regulators using metal diaphragms.

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)

Cg = Wide-open gas sizing coefcient from Table 4

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 13, 14, 15, 16, and 17 are in

pounds/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.

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

capacity Qa for P2a and Qb for P2b.

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)

NPS 1/4 Type 95H 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 (29,5 Nm3/h)

P2a = 15 psig (1,0 bar)

Qb = 1600 SCFH (42,9 Nm3/h)

P2b = 30 psig (2,1 bar)

1600 - 1100 1600 - Q

30 - 15 30 - 20

=

Q = 1270 SCFH

42,9 - 29,5 42,9 - Q

2,1 - 1,0 2,1 - 1,4

Q = 34,0 Nm3/h

=

Note

The same interpolation procedure can

be used for different inlet pressures.

An alternative method for interpolating capacities is to

back calculate Cv’s as shown in Table 2.

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

1. To obtain capacities for regulators using metal diaphragms, multiply the table values by 0.8.

- continued -

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, pounds/h

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

gauge inlet pressure to obtain absolute inlet pressure)

Cs = Wide-open steam sizing coefcient from Table 4

For pressure drops lower than critical (absolute

outlet pressure greater than one-half absolute inlet

pressure), use the sizing nomographs in Fisher

Catalog 10, or the Fisher Sizing Program.

Water Capacities

All water capacities in Tables 18, 19, 20, 21, and 22

are in GPM. Capacities in Tables 18, 19, and 21

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 Fisher® Catalog 10, or the Fisher Sizing

Program using the Cv coefcients given in Table 4.

The Km values listed in Table 4 can be used to predict

choked ow on liquid service.

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