Fisher Types 1098-EGR and 1098H-EGR pilot-operated pressure reducing regulators for natural gas distribution systems, fuel gas supply to industrial boilers, furnaces, ovens and mixers, large commercial and industrial establishments, plant air and liquid service. Inlet pressure is reduced through the pilot to load the actuator diaphragm; the two-path control system responds quickly to outlet changes while the pilot amplifies small changes for precise control. Knife-edged seats in the cage-guided metal valve plug give bubble-tight shutoff; differential as low as 1 psi / 70 mbar and no atmospheric bleed. Top-entry in-line maintenance, quick change trim package and in-service travel inspection. Body sizes NPS 1, 2, 3, 4, 6, 8 x 6 and 12 x 6 (DN 25 to 300 x 150): cast iron NPT or CL125 FF (NPS 1-2) and CL125 FF (NPS 3-6); steel or stainless steel NPT, CL150 RF, CL300 RF, CL600 RF, BWE, SWE or PN 16/25/40 (NPS 1-2), CL150/300/600 RF, BWE or PN 16/25/40 (NPS 3-6), CL150/300/600 RF or BWE (8 x 6 and 12 x 6). Main valve maximum inlet pressure 400 psig / 27.6 bar or body rating limit, whichever is lower; maximum pilot supply pressure 600 psig / 41.4 bar. Type 1098 actuator sizes 30, 40 and 70; Type 1098H size 30. Pilots 6351, 6352, 6353, 6354L/M/H, 61L, 61LD, 61LE, 61H, 61HP and Y600AM, with outlet ranges from 4 in. w.c. to 300 psig depending on pilot and spring. Body in cast iron, WCC steel or CF8M stainless steel; NBR (-20 to 180 °F), FKM (0 to 300 °F) or EPR (-20 to 275 °F) elastomers. Options: NACE construction, monitor configuration, boiler fuel construction, aqueous (liquid) service construction and Whisper Trim noise abatement cages (up to 30 dBA reduction). Approximate weight 55 to 1187 lb depending on body size and actuator.
