MR98 Series Operational Schematics (continued) Principle of Operation Relief or backpressure valves respond to changes in upstream pressure. Pressure changes register under the diaphragm (see Figure 2) through a registration hole in the valve body or through an external control line. When the pressure increases above the spring setting, the pressure underneath the diaphragm overcomes the spring compression. This causes the valve plug to move away from the orifice. The flow path through the valve is open and excess pressure is vented. When upstream pressure drops below setpoint, the valve closes. Differential relief valves are used to maintain a differential pressure between the controlled pressure and loading pressure of a system. The spring setting determines the differential. The differential relief valve responds to both controlled pressure and loading pressure and opens or closes as these pressures change. If the loading pressure increases, pressure on the upper side of the diaphragm increases. The valve plug moves closer to the orifice and restricts the flow through the relief valve. When loading pressure decreases, pressure on the upper side of the diaphragm decreases. This allows the valve plug to move away from the orifice and allow more flow through the differential relief valve (to atmosphere or back into the system). The differential relief valve opens and closes in response to changes in the controlled pressure. In this way, the differential pressure between the controlled and uncontrolled pressures is maintained. 5 MR98 Series Table 1.

Installation Schematics for Types MR98LD and MR98HD Relief Valves 10 MR98 Series Installation ! Warning Personal injury or system damage may result if this backpressure regulator, relief or differential relief valve is installed where service conditions could exceed the limits given on the Specifications section and/or regulator nameplate. Additionally, physical damage to the backpressure regulator or relief valve may result in personal injury or property damage due to escaping of accumulated gas. To avoid such injury and damage, install the backpressure regulator or relief valve 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. Before installing the regulator: • Unpack the backpressure regulator or relief valve and remove the protective shipping plugs from the end connections of the body and the pressure connection in the spring case. • Check the backpressure regulator or relief valve 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 backpressure regulator or relief valve is in the same direction as the arrow on the body. • For a differential relief valve, the design of the valve isolates the diaphragm and pressure loading spring case from the main flow stream. The higher pressure is measured inside the body through a registration hole on the inlet side of the body or through the external control line. If loading pressure is required, connect the loading pressure line to the 1/4 NPT connection in the spring case. If loading pressure is not required, vent this connection to the atmosphere. Overpressure Protection ! Warning Overpressuring any portion of this equipment may result in equipment damage, leaks in the relief valve/ backpressure regulator or personal injury due to bursting of pressurecontaining parts. Relief, differential relief or backpressure ranges are from 2 to 375 psig / 0.14 to 25.9 bar. The individual spring range of your valve is stamped on the nameplate. Maximum inlet pressure depend upon body materials and temperatures. See Specifications section or the maximum inlet pressure of the valve and the maximum spring case loading pressures stamped on the nameplate of Types MR98LD, MR98HD and MR98HHD. The valve should be inspected for damage after any overpressure condition. Vents and Relief Valve Outlet ! Warning If using an MR98 Series backpressure regulator, relief or differential relief valve on hazardous or flammable gas service, personal injury and property damage could occur due to fire or explosion of vented gas that may have accumulated. To prevent such injury or damage, provide piping or tubing to vent the gas to a safe, well-ventilated area. All vents 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 vent or vent line. 11 MR98 Series Table 4.

Install remote vent lines in the spring case and outlet openings. The vent lines must have the largest practical diameter and be as short as possible with a minimum number of bends or elbows. Install the vent line according to applicable federal, state and local codes and regulations. Types MR98L, MR98H and MR98HH 1. Loosen the jam nut (key 17, Figures 4, 6, 7 and 10). 2. To increase the set pressure or pressure setting, turn the adjusting screw (key 15) clockwise. Turn the adjusting screw counterclockwise to decrease the set pressure or pressure setting. 3. Tighten the jam nut (key 17). Startup Note The Specifications section and Table 4 show the maximum inlet and the differential pressures for specific constructions. Use pressure gauges to monitor inlet pressure, outlet pressure and any loading pressure during startup. Key numbers are shown in Figures 4 through 10. Types MR98LD, MR98HD and MR98HHD Turn the handwheel (key 38, Figures 5, 8 and 9) clockwise to increase differential pressure setting. Turn the handwheel counterclockwise to decrease the differential pressure setting. Shutdown Relief Valve 1. Check that proper installation is completed and downstream equipment has been properly adjusted. 1. Close the upstream shutoff valve to the regulator inlet. 2. Make sure all block and vent valves are closed. 2. Close the downstream shutoff valve to the regulator outlet. 3. Decompress the control spring by turning the adjusting screw (for Types MR98L, MR98H and MR98HH) or handwheel (for Types MR98LD, MR98HD and MR98HHD) counterclockwise. 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 set pressure according to the Adjustment procedure. Adjustment Each unit is factory set for the pressure setting specified on the order or at the mid-point of the spring range. The allowable spring range is stamped on the nameplate. If a pressure setting beyond the indicated range is required, replace with the appropriate spring. Be sure to label the regulator/valve to indicate the new pressure range. Always use a pressure gauge to monitor pressure when making adjustments. All MR98 Series regulator springs can be backed off to zero pressure. Recommended set pressure ranges available, maximum inlet pressures and temperatures and color codes of the respective springs are shown in the Specifications section and Table 3. 3. Slowly open the downstream vent valve to vent downstream pressure. 4. Leave the downstream vent valve open to vent inlet pressure and to release all remaining pressure in the regulator by opening the upstream vent valve or by turning the adjusting screw fully counterclockwise. Differential Valve (Pressure-Loaded System) 1. Close the upstream shutoff valve to the regulator inlet. 2. Close the downstream shutoff valve to the regulator outlet. ! Warning To avoid damage of internal parts from a pressure-loaded actuator, carefully vent the regulator spring case pressure prior to inlet pressure. 3. Vent the loading pressure slowly to release pressure in the spring case. 13 MR98 Series Table 7.

Backpressure Regulator 1. Close the upstream shutoff valve to the regulator inlet. 2. Close the downstream shutoff valve to the regulator outlet. 3. To avoid internal damage due to reverse pressurization of main valve components, bleed backpressure regulator inlet pressure first before bleeding outlet pressure. 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 relief valve or regulator from system pressure and relieving all internal pressure from the relief valve or regulator. To avoid possible personal injury from spring or pressure-loaded actuator, make sure that the adjusting screw is completely backed off or the spring case pressure is vented prior to disassembly. 14 Diaphragm Material Neoprene (CR) Fluorocarbon (FKM) Ethylenepropylene (EPDM) Metal Metal Neoprene (CR) Fluorocarbon (FKM) Ethylenepropylene (EPDM) Metal Neoprene (CR) Fluorocarbon (FKM) Ethylenepropylene (EPDM) Metal Number of Diaphragm 1 2 2 1 2 1 2 2 2 1 2 2 2 Otherwise, the spring load or loading pressure could forcefully eject the spring case. Relief valves or 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® relief valves and regulators. Due to normal wear or damage that may occur from external sources, this relief valve or backpressure 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 and damage that may occur from external sources, relief valve parts such as the O-rings, gaskets, diaphragm, orifice and valve plug should be inspected periodically and replaced as necessary. The frequency of inspection and replacement depends upon the severity of service conditions or the requirements of state and federal laws. Instructions are given below for disassembly of the MR98 Series. These valves do not have to be removed from the pipeline to inspect internal parts. Suitable lubricants are indicated on the assembly drawings. Apply the recommended lubricants as the relief valve is being reassembled. Refer to Figures 4 to 10 while servicing the relief valve. Flange Cap Screw Torque Inspection Retorquing of spring case cap screws may be necessary for some MR98 Series regulators after a period of use. Retorque the cap screws as follows: MR98 Series 1. Shut down the relief valve or backpressure regulator. Refer to Shutdown section for the proper procedure. 2. Retighten the cap screws (key 16) in a crisscross pattern. See Table 6 for proper torque values. 3. Follow the Startup section to repressurize the relief valve or backpressure regulator. 4. Refer to the Disassembly to Replace Diaphragm and Seats section as needed. Disassembly to Replace Diaphragm and Seats Caution Metal diaphragms have thin sharp edges. To avoid hand cuts, be careful when handling the diaphragm, particularly the diaphragm edge. If the relief valve is leaking, the diaphragm may be ruptured or the seating surfaces nicked or scratched. Proceed as follows to inspect or replace the diaphragm, orifice and valve plug. 1. Shut down the backpressure regulator or relief valve. Refer to Shutdown section for the proper procedure. 2. For Types MR98LD, MR98HD and MR98HHD: Release all spring compression by turning the adjusting screw or handwheel (key 33 or 38) counterclockwise until it turns freely without resistance from the spring. For Types MR98L, MR98H and MR98HH: Relieve the spring tension by loosening the jam nut (key 17) and turning the adjusting screw (key 15) counterclockwise. 3. Remove cap screws (key 16) and lift off the spring case (key 2), upper spring seat (key 9) and relief valve spring (key 11). Lift out the diaphragm unit which includes the lock nut (key 31), lock washer (key 28), pusher post (key 10), gasket (key 29), lower spring seat (key 8), diaphragm (key 12), diaphragm head (key 21 for Types MR98L and MR98LD, all body sizes and for Types MR98H and MR98HD, 1-1/2 and 2 in. / DN 40 and 50 body sizes), valve plug (key 4) and Type MR98HD has another washer (key 58) and an O-ring (key 45). 4. Check the orifice (key 3) for wear or damage. If it needs to be replaced, unscrew the valve plug guide (key 7) and then the orifice. The valve plug (key 4) can be removed by sliding it off of the pusher post (key 10). 5.

Slip the valve plug (key 4) onto the pusher post (key 10). Place a gasket (key 29) on the shaft of the pusher post over the threaded portion until it rests on the base of the post. If elastomer diaphragm (key 12) is used, place a metal washer (key 58) on top of the gasket. For Type MR98H, 1-1/2 to 2 in. / DN 40 to 50 with metal diaphragm, place another gasket on the shaft of the pusher post until it rests on the bottom diaphragm head (key 21), see Figure 7. Note If a metal diaphragm is to be replaced by an elastomer diaphragm or an elastomer diaphragm by a metal diaphragm, a new pusher post is required. Each diaphragm material requires a different pusher post length and make sure the proper number of metal or elastomer diaphragm that will be used is followed. Refer to the Parts List section or Table 7 for the correct number of diaphragm to be used. 9. See Figures 4 to 10. For the metal diaphragms (key 12), replace the large diaphragm gasket (key 19) on the surface of the body (key 1) that will support the diaphragms. There will be two diaphragms used per regulator, except for 1/4 NPT Types MR98L and MR98LD with 2 to 7 psi / 0.1 to 0.5 bar spring range, which use only one 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 diaphragm is being used then the raised surface should be facing down (towards the body) (see Figure 2). For elastomer diaphragms, the printed side should be facing upwards when installed. 15 MR98 Series 10. Slip the lower spring seat (key 8) and lock washer (key 28) back onto the pusher post (key 10). Lubricate the threads of the pusher post and tighten the pusher post lock nut (key 31) until the lock washer is flat and then turn the nut an additional 1/8 to 1/4 turn.
