MR95 Series

Principle of OperationThe 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 orifice, restricting fluid flow 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 orifice. This allows fluid flow through the body to the downstream system. Types MR95H, MR95L, MR95HP and MR95HT use spring force to regulate outlet pressure. Types MR95HD, MR95HDP and MR95LD use spring force to maintain a differential pressure between spring case loading pressure and outlet pressure.

InstallationThe MR95 Series regulators may be installed in any position, as long as flow 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.

NACE ComplianceOptional 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 specified 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 Office for special ordering instructions. Customers have the responsibility to specify correct materials. Environmental limitations may apply and shall be determined by the user.

Capacity DataThe 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 flow 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 flow:

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, find 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 bar1/4 NPT Type MR95H with 15 to 30 psig / 1.0 to 2.1 bar spring rangeP2 = 20 psig / 1.4 barDetermine air capacity, QSolution:Qa = 1100 SCFH / 28.8 Nm3/hP2a = 15 psig / 1.0 barQb = 1700 SCFH / 46.5 Nm3/hP2b = 30 psig / 2.1 bar

1700 - 1100 1700 - Q 30 - 15 30 - 20

=

Q = 1300 SCFH

MR95 Series

46.5 - 28.8 46.5 - Q 2.1 - 1.0 2.1 - 1.4

Note The same interpolation procedure can be used for different inlet pressures.

Contact your local Sales Office if you should have any questions about selecting the proper regulator.

Air CapacitiesRegulating capacities at selected pressures and outlet pressure flows 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 specific gravity natural gas, 0.808 for propane, 0.707 for butane or 1.018 for nitrogen. For gases of other specific gravities, divide by the square root of the appropriate specific gravity.Then, if capacity is desired in Nm3/h at 0°C and 1.01325 bar, multiply SCFH by 0.0268.Capacities in Tables 11, 12, 13, 14 and 15 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 flow 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 flow, 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 coefficient from Table 6

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 CapacitiesCapacities in Tables 16, 17, 18, 19 and 20 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 flow 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 flow, lbs/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 coefficient from Table 6

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 CapacitiesAll water capacities in Tables 21, 22, 23, 24 and 25 are in gallons per minute (GPM). Capacities in Tables 21, 22 and 24 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 flow capacity for liquid relief valve sizing, refer to the Fisher Sizing Program using the Cv coefficients given in Table 6. The Km values listed in Table 6 can be used to predict choked flow on liquid service.

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