The main valve nameplate is located on the main valve body. The pilot relief pressure range appears on the pilot nameplate. Principle of Operation As long as inlet pressure remains below set pressure, the pilot control spring keeps the pilot valve plug closed (Figure 2). This pressure provides the loading pressure to help the main valve spring keep the main valve plug tightly shutoff. An inlet pressure rise above the set pressure overcomes the pilot control spring and opens the pilot valve plug. Loading pressure bleeds out the pilot exhaust faster than it can be replaced through the pilot restriction. This permits inlet pressure to unbalance the main valve plug and open the main valve. As inlet pressure drops below set pressure, the pilot control spring closes the pilot valve plug. Loading pressure again builds up to close the main valve plug. ! Warning Personal injury, equipment damage or leakage due to escaping gas (or liquid) or bursting of pressure-containing parts may result if the relief valve is installed where its capabilities can be exceeded or where conditions exceed any ratings of the adjacent piping or piping connections. To avoid this, install a Type 63EG-98HM relief valve where: • Service conditions are within unit capabilities (including those given in the Specifications section) • Service conditions are within applicable codes, regulations or standards Additionally, physical damage to the relief valve could break the pilot off the main valve, causing personal injury and property damage due to escaping gas (or liquid). To avoid such injury or damage, install the unit in a safe location. 3 TO OR GREATER THAN SETPOINT) Type 63EG-98HM Table 4.

Minimum differential is defined as the difference between the inlet pressure to the main valve body and the exhaust pressure from the pilot outlet. If the pilot exhaust is piped to the immediate downstream system, the differential is between the inlet and outlet pressure of the backpressure regulator. The pilot exhaust also may be discharged to atmosphere. 2. CL150 steel body is limited to 290 psig / 20 bar. 1. Call a qualified personnel when installing, operating, and maintaining relief valves and backpressure regulators. Before installing, inspect the main valve, pilot and tubing for any shipment damage or foreign material that may have collected during crating and shipment. Make certain the body interior is clean and the pipelines are free of foreign material. Apply pipe compound only to the external pipe threads with an NPT body, or use suitable line gaskets and good bolting practices with a flanged body. 2. A Type 63EG-98HM may be installed in any orientation, as long as flow through the valve matches the direction of the arrow on the main valve body. ! Warning Type 63EG relief valves vent from the main valve outlet and from the pilot exhaust. In hazardous or flammable gas service, personal injury, death or property damage may occur due to fire or explosion or exposure of vented gas (or liquid) that has accumulated. To 4 prevent such injury or damage, provide piping or tubing to vent the gas (or liquid) to a safe location. The exhaust piping must be designed and installed to guard against excessive flow restriction. This piping must be protected against condensation or anything else that could clog it. For safety during shutdown, vent valves are required immediately upstream and downstream of the main valve on a backpressure or bypass installation. 3. If system operation is necessary during maintenance or inspection, install isolating and vent valves as needed. 4. A relief valve must be installed so that the pilot exhausts properly and in a safe place. Make sure to keep the pilot spring case vent open to atmospheric pressure. 5. If the exhaust is to be piped to the main valve outlet or remotely vented, install obstruction-free tubing or piping with a minimum number of bends into the 1/2 NPT pilot exhaust connection. Type 63EG-98HM 6. If using pipe, apply a good grade of pipe compound to the external pipe threads before making the connection. Install tubing or piping into the appropriate pilot connection. 7. Set pressure is defined as the pressure at which the pilot starts to discharge. The set pressure of a unit is adjusted by changing the control spring compression on the pilot, by using the adjusting screw. 8. Each pilot is factory set for the relief set pressure specified on the order. If no setting is specified, set pressure is factory set at the midrange of the pilot control spring. Startup and Adjustment Key numbers are referenced in Figures 4, 5 and 6 unless otherwise indicated. 1. With proper installation and adjustment completed, slowly open the upstream shutoff valve while using gauges to monitor pressure. On backpressure or bypass applications using an isolating bypass, also open the downstream shutoff valve and close the bypass valve. 2. If set pressure adjustment is necessary, monitor inlet pressure with a gauge during the adjustment procedure. Pilot Adjustment Adjust the set pressure by loosening the pilot jam nut (key 17) and turning the pilot adjusting screw (key 15) clockwise to increase or counterclockwise to decrease the set pressure. When the required set pressure is maintained for several minutes, tighten the jam nut to lock the adjusting screw in position. Shutdown Relief Installations Slowly close the upstream shutoff valve. Release all pressure from the main valve and pilot by opening the upstream vent valve. Backpressure or Bypass Installations Slowly close the upstream shutoff valve while opening the bypass valve if an isolating bypass is used. Then close the downstream shutoff valve and open both vent valves to release all pressure from the main valve and pilot. Maintenance Relief valve and backpressure regulator parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of inspection and replacement of parts depends upon the severity of service conditions or the requirements of local, state and federal regulations. Due to the care Emerson™ takes in meeting all manufacturing requirements (heat treating, dimensional tolerances, etc.), use only replacement parts manufactured or furnished by Emerson. All O-rings, gaskets and seals should be lightly lubricated with a good grade of general purpose grease and installed gently rather than forced into position. Be certain that the nameplates are updated to accurately indicate any field changes in equipment, materials, service conditions or pressure settings. ! Warning To avoid personal injury and equipment damage, isolate the valve from all pressure. Cautiously release pressure from the valve before attempting disassembly.

Install the spring (key 9) and place the fl ange O-ring (key 21) on the fl ange plug (key 27). Install the fl ange plug; if necessary, compress the spring enough to ensure secure engagement of plug and body fl ange threads before fi nal tightening of the plug. Type MR98h Pilot ! WARnIng To avoid personal injury, property damage or equipment damage caused by sudden release of pressure or uncontrolled process fluid, do not attempt any maintenance or disassembly without first isolating the regulator from system pressure and relieving all internal pressure from the regulator. 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 and damage that may occur from external sources, relief valve parts such as the O-rings, gaskets, diaphragm, orifi ce 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. The following instructions explain the disassembly of the Type MR98H relief or backpressure pilot. Lightly apply a good quality lubricant when reassembling. Key numbers are referenced in Figure 7.
