Fisher EZL Series regulators are accurate pilot-operated, pressure balanced, soft-seated regulators. They are designed for use in natural gas distribution applications such as district regulating stations and commercial/industrial meter sets. They provide low differential, smooth, reliable operation, tight shutoff and long life.FeaturesLow Differential Applications—Can accurately control at pressure differentials as low as 2.9 psid / 0,2 bar dBubble-Tight Shutoff—A knife-edged metal plug and soft seat provide bubble tight shutoff for use in applications where positive shutoff is required such as dead-end systems.Absolutely No Atmospheric Bleed—Eliminates nuisance and wasteful bleed gas to atmosphere by utilizing a pilot-operated control system, which bleeds 100% of the gas to the downstream system.Easy In-Line Maintenance—Top entry design enables easier maintenance. Trim parts can be inspected, cleaned and replaced without removing the body from pipeline.Precise Pressure Control—Provides stable and accurate downstream pressure control regardless of load changes or inlet pressure variations.Travel Indicator—Simplifies in-service inspection and system troubleshootingFull Pressure Rating—The equal inlet and outlet pressure rating of 290 psig / 20 bar, which allows easier selection and requires no special startup or shutdown procedures.Integral Slam Shut Configurations—Type EZLOSX interrupts gas service during an overpressure or underpressure condition.SpecificationsAvailable ConfigurationsType EZL: Control range of 7 inches w.c. to 300 psig / 17 mbar to 20,7 barType EZLOSX: Type EZL with an integrated Type OS2 slam-shut deviceBody Sizes and End Connection StylesBody Sizes: NPS 2, 3, or 4 / DN 50, 80, or 100Main Valve Body Material: WCC or Cast ironEnd Connection Styles: NPT, SWE, BWE, CL150 RF, CL250 RF, CL300 RF, CL600 RF, or CL125 FFMaximum Allowable PressuresInlet Pressure: 290 psig / 20,0 barOutlet (Casing) Pressure: 290 psig / 20,0 barEmergency Casing Pressure: 290 psig / 20,0 barOperating Differential Pressure: 290 psid / 20,0 bar dOutlet Pressure Range0.25 to 350 psig / 0,02 to 24,1 barTemperature Capabilities-20° to 180°F / -29° to 82°C
