Gas Pilot Operated Regulators Gas Fluids coming in Back Pressure Regulator Liquid Heater Treater Kimray Back Pressure Regulator Horizontal Separator Back Pressure Regulators Back Pressure Regulator Maintains constant upstream pressure Intermittent bleed pilot Pressure range: 5 to 280 psig Single adjustment Accurate control Full line size opening Available in cast iron, ductile iron, or steel Available in sizes 1” through 6” Back Pressure Regulator • What do they do? • Where would I see one? • How do they work? Back Pressure Regulator Below Setpoint-Closing Valve Above Setpoint - Venting At Setpoint – Both Ports Closed The Truth About P-Nuts Understanding a few basic facts about the Pilot Plug will equip you to trouble shoot 90% of Pilot and Regulator problems. The Truth About P-Nuts The Pilot Plug operates within a few thousandths of an inch of both its seats. Gas flowing past the Pilot Plug must be clean. Gas flowing past the Pilot Plug must be dry. A loose seat can keep the lower Pilot Plug port from opening.
