Principle of OperationThe Type 95 (refer to figure 4) is a direct operated reg-ulator. Downstream pressure is registered internallythrough the body to the under side of the diaphragm.When the downstream pressure is at or above the setpressure, the disk is held against the seat, and there isno flow through the regulator. When demand in-creases, downstream pressure drops slightly allowingthe spring to extend, moving the stem down and thedisk away from the seat. This allows flow through thebody to the downstream system. Types 95H, 95L,95HT, 95HC and 95LC use spring force to regulateoutlet pressure. Types 95HD and 95LD use springforce to maintain a differential pressure betweenspring case loading pressure and outlet pressure.

Capacity DataThe capacity information on the following pages isbased on three offset factors, 10, 20 and 40 percent.Offset, or droop, is deviation from the set point of theregulator, and is usually stated in percentage of setpoint value.
For example, refer to the air flow rate curve in figure 5.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 standardcubic feet per hour (8.5 cubic meters per hour) flowrate. Capacity at 10 percent offset is read at the inter-section of a line projected horizontally to the right fromthe 13.5 psig (0.5 bar) outlet pressure point and the
100 psig (6.9 bar) inlet curve. The 13.5 psig (0.9 bar)is derived by applying the offset factor of 10 percent tothe regulator setting of 15 psig (1.0 bar). The samemethod is employed for 20 percent offset, except thecapacity value is read at the 12 psig (0.8 bar) outletpressure point, 20 percent less than the 15 psig (1.0bar) setting.
For highest capacity and the most accurate controlwithin a particular type of the 95 Series regulators, usethe lowest range spring that can be adjusted to the
Bulletin 71.1:95
desired set point (see table 5 for part numbers of ap-propriate springs for each body size). See table 1 forsizing example for the Types 95HD and 95LD regula-tors.
If closer control is necessary, a regulator of larger ca-pacity or different design should be selected, so thatthe necessary flow can be obtained with a smaller off-set factor.
Sometimes it may be necessary to interpolate the ca-pacity table data to determine capacity for outlet set-tings not given. To maintain accuracy, it is importantwhen interpolating to stay within a spring range if pos-sible. The following is a procedure for interpolating thedata to calculate flow:
1. Determine which spring is to be used.
2. Find the two outlet settings (P2a & P2b) that bracket theactual outlet pressure P2.
3. For a given body size and inlet pressure, find the capacityQa for P2a and Qb for P2b.
4. Use the following formula to determine the interpolatedcapacity (Q).
Qb - QP2b - P2
=Qb - QaP2b - P2a
Example:
P1 = 100 psig1/4 inch Type 95H with 15 to 30 psigspring range
P2 = 20 psigDetermine air capacity, Q.
Solution:
Qa = 1000 SCFH
1900 - 1000 1900 - Q30 - 20
=30 - 15
Qb = 1900 SCFHP2b = 30 psigP2a = 15 psig
Q = 1300 SCFH
NOTE: The same interpolation procedure can be usedfor different inlet pressures.
An alternative method for interpolating capacities is toback calculate Cv’s as shown in table 2.
Contact your nearest Fisher Representative if youshould have any questions about selecting the properregulator.

Air CapacitiesRegulating capacities at selected pressures and outletpressure flows are given in SCFH (60_F and 14.7psia) of air at 60_F. To determine the equivalent ca-

Bulletin 71.1:95
pacities for other gases, multiply the table capacitiesby the following appropriate conversion factors: 1.29for 0.6 specific gravity natural gas, 0.810 for propane,0.707 for butane, or 1.018 for nitrogen. For gases ofother specific gravities, divide by the square root of theappropriate specific gravity.Then, if capacity is desired in normal cubic meters perhour at 0_C and 1.01325 bar, multiply SCFH by0.0268.
Capacities in tables 8, 9 and 11, are for regulators us-ing elastomer diaphragms. Depending on regulatorconstruction, a multiplier must be used to convert tocapacities for regulators using metal diaphragms.
To determine wide-open flow capacity for relief valvesizing of air at a temperature of 60_F, use the equa-tion for critical pressure drops (absolute outlet pres-sure equal to one-half or less than one-half the abso-lute inlet pressure).
Q = P1(abs)Cg
where,
Q = Gas flow, SCFH (60_F and 14.7 psia)
P1(abs) = Absolute inlet pressure psia (add 14.7 psito gauge inlet pressure to obtain absoluteinlet pressure)
Cg = Wide-open gas sizing coefficient from table 4.
For pressure drops lower than critical (absolute outletpressure greater than one-half the absolute inlet pres-sure), use the sizing nomographs in Fisher Catalog10, or the Fisher Sizing Program.
To obtain capacities in normal cubic meters per hourat 0_C and 1.01325 bar, multiply the capacity deter-mined in SCFH by 0.0268.
Steam Capacities
Capacities in tables 13, 14, 15, 16, and 17 are inpounds per hour of saturated steam. To obtain capaci-ties in kilograms per hour, multiply the capacities givenin the table by 0.4535. Capacities have been calcu-lated for stainless steel diaphragms only since steamservice exceeds the elastomer diaphragm temperaturelimits.
To determine wide-open flow capacity for relief valvesizing of steam, use the equation for critical pressuredrops (absolute outlet pressure equal to one-half orless than one-half absolute inlet pressure).
Q = P1(abs)Cs
6
where,
Q = Steam flow, lb/hr
P1(abs) = Absolute inlet pressure, psia (add 14.7 psito gauge inlet pressure to obtain absolute inletpressure)
Cs = Wide-open steam sizing coefficient from table 4.
For pressure drops lower than critical (absolute outletpressure greater than one-half absolute inlet pres-sure), use the sizing nomographs in Fisher Catalog10, or the Fisher Sizing Program.
Water Capacities
All water capacities in tables 18, 19, 20, 21 and 22 arein gallons per minute. Capacities in tables 18, 19 and21 are for regulators using only elastomer diaphragms.Depending on regulator size, a multiplier, given inthese tables, must be used to convert to capacities forregulators using metal diaphragms.
To determine flow capacity for liquid relief valve sizing,refer to Fisher Catalog 10, or the Fisher Sizing Pro-gram using the Cv coefficients given in table 4. The Kmvalues listed in table 4 can be used to predict chokedflow on liquid service.
To convert capacities to cubic meters per hour, multi-ply gallons per minute by 0.2271.
InstallationThe 95 Series regulators may be installed in any posi-tion, as long as flow will be in the same direction asthat indicated by the body arrow. The Types 95H, 95L,95HT, 95HP 95HC and 95LC regulators should beinstalled so that their spring case vents are protectedfrom anything that might clog them.

2. Select type number and springrange using tables 3 and 4.
Since the bias set is 10 psig, select the Type95LD with a 5 to 15 psig spring range. (The Type95LD will withstand the pressure for the applica-tion, and also has the lightest spring available.)
Since the bias set is 0.7 bar, select the Type 95LD with a0.3 to 1.0 bar spring range. (The Type 95LD will withstandthe pressure for the application, and also has the lightestspring available.)
3. Using the Fisher SizingProgram, calculate a Cg from datagiven in the capacity tables. Usethe table inlet pressure closest tothe service condition. Also calcu-late using the table outlet pressurewhich is closest to the spring bias.
For the purpose of sizing, use the spring set point(bias) of 10 psig as outlet pressure, and an inletpressure of 150 psig.
The closest capacity data in Tables 4 and 8shows the following:
C1 = 35 (Table 4)P1table = 150 psigP2table = 10 psigDroop/offset = 10 psig x 20% = 2 psignPtable = 150 psig - (10 psig - 2 psig) = 142 psidQ = 1400 SCFH for size 1/2 inch Type 95LD at20% droop/offset
For the purpose of sizing, use the spring set point (bias) of0.7 bar as outlet pressure, and an inlet pressure of 10.3 bar.
The closest capacity data in Tables 4 and 8 shows thefollowing:
C1 = 35 (Table 4)P1table = 10.3 barP2table = 0.7 barDroop/offset = 0.7 bar x 20% = 0.1 barnPtable = 10.3 bar - (0.7 bar - 0.1 bar) = 9.7 bar differentialQ = 37.5 m3/h(n) for size 1/2-inch Type 95LD at 20%droop/offset
4. Use the information in Step 3 tocalculate Cg using the FisherSizing Program.
Cg calculated = 8.5 Cg calculated = 8.5
5. Calculate flow for applicationbased upon actual conditions andcalculated Cg.
P1 = 135 psigP2max = 40 psigDroop/offset = 10 psig x 20% = 2 psignP actual = 135 psig - (40 psig - 2 psig) = 97 psidCg calculated = 8.5Q = 1248 SCFH air with droop/offset equal to20% of spring bias
P1 = 9.3 barP2max = 2.8 barDroop/offset = 0.7 bar x 20% = 0.1 barnP actual = 9.3 bar - (2.8 bar - 0.1 bar) = 6.6 bar differentialCg calculated = 8.5Q = 33.4 m3/h(n) air with droop/offset equal to20% of spring bias

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 = 37.9 liters per minute
2. Select Type number and springrange using tables 3 and 4
The Type 95L with a 13 to 30 psig pressure range,will provide the lightest spring for the application.
The Type 95L with a 0.9 to 2.1 bar pressure range, willprovide the lightest spring for the application.
3. Because the capacity table for aType 95L in Table 18 does notprovide data for the exact applica-tion, choose the values from thetable that most closely match theapplication. A 1-inch Type 95L fitsthe closest.
P1table = 30 psigP2table = 20 psigDroop/offset = 20 psig x 20% = 4 psignPtable = 30 psig - (20 psig - 4 psig) = 14 psidQ = 13 gpmKm = 0.67 (See table 4)

4. Use information in Step 3 tocalculate Cv using Fisher SizingProgram.
Cv calculated = 3.47 Cv calculated = 3.41
5. Determine flow capacity of Type95 with actual conditions using Cvcalculated from Step 4
Cv = 3.47P1 = 25 psigP2 = 18 psigDroop/offset = 18 psig x 20% = 3.6 psignP actual = 25 psig - (18 psig - 3.6 psig) = 10.6 psid

1. Pressure ranges given for Types 95L, 95H, 95HT, 95HP, 95HC and 95LC regulators indicate actual outlet pressure. For Types 95LD and 95HD regulators,the pressure ranges indicate the differential pressure that can be obtained with the indicated spring. The differential pressure (spring setting) is added to thespring case loading pressure to determine the actual outlet pressure.
2. Type 95H is recommended where close regulation is not required. Type 95L is recommended where close regulation is required.
