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 fluids. 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 orifice 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 orifice 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 fixtures, 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.

MR95 Series Operational Schematics 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. 4 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 orifice and restricting 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.

Figure 2. MR95 Series Operational Schematics (continued) 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 flow 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 orifice. 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 flow stream and increasing the fluid flow through the regulator. Downstream pressure rises back to the desired differential level. 5 MR95 Series Table 1.

Differential Pressure Regulator Installation Schematics Installation Before installing the regulator: ! 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 Specifications 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 flow 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. • 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 flanged bodies. • Make sure gas flow 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. 11 MR95 Series 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: 1. Check that proper installation is completed and downstream equipment has been properly adjusted. • Overpressured • Installed where service conditions could exceed the limits given in the Specifications section and on the appropriate nameplate • Where conditions exceed any ratings of adjacent piping or piping connections 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. 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 Specifications section and Tables 3 and 4 show the maximum inlet, the differential and the outlet pressures for 12 specific constructions. Use pressure gauges to monitor inlet pressure, outlet pressure and any loading pressure during startup. 2. Make sure all block and vent valves are closed. 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 first 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. 13 MR95 Series Replacement or Maintenance of Orifice and Valve Plug If it appears that the valve does not shut off tightly, the orifice 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 orifice (key 3). If damage is noted, unscrew the orifice 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 fluid leaks or vents to the spring case (pressure reducing regulators) or the loading pressure seems to leak to the downstream 14 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.

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 flat surface down and the thread stem up (metal diaphragm pusher post has a recessed diameter in the bottom surface). Then, find one smaller composition gasket (key 29) and fit 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. R eplace 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 finger 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 16 completely removed and turn it clockwise. This allows proper positioning of the diaphragm (key 12) to permit full travel of the valve plug (key 4). Finish tightening the cap screws (key 16). See Table 8 for proper torque values. 13. Complete reassembly procedures and turn the adjusting screw (key 15) or handwheel (key 38) to produce the desired outlet pressure. For Types MR95L, MR95H, MR95HP and MR95HT, tighten the jam nut (key 17) to maintain the desired setting. Replacement of Packing (Types MR95LD and MR95HD only) Leakage around the adjusting screw may indicate worn packing material. Follow the instructions below to replace the packing rings. 1. Shut down the regulator. Refer to “Shutdown” section for the proper procedure. 2. Take out the machine screw (key 41) and lift off the washer (key 44) and handwheel (key 38). 3.
