FISHER EZL功能特點：
低壓差應(yīng)用—可在壓力差低至 2.9 psid / 0.2 bar d 的情況下執(zhí)行的控制
氣密切斷—銳利的金屬塞和軟閥座提供氣密切斷，可用于終端系統(tǒng)等需要正壓關(guān)閉的應(yīng)用。
完全無大氣排放—利用先導(dǎo)式控制系統(tǒng)將所有氣體排放至下游系統(tǒng)，因此不會將任何有害廢氣排放至空氣中。
簡單直通式維護—頂部進入式設(shè)計使得維護更加簡單。 無需從管線上卸下閥體即可檢查、清潔及更換閥內(nèi)件。
壓力控制—無論負載或入口壓力如何變化，都能夠提供穩(wěn)定、的下游壓力控制。
行程指示器—簡化了維護過程的檢測和系統(tǒng)故障排查
完整壓力等級—290 psig/20 bar 相等的入口和出口壓力等級，更易選擇，無需特殊的啟動或關(guān)閉程序。
一體化切斷組態(tài)—EZLOSX 型在出現(xiàn)過壓或失壓時會中斷供氣。

其他技術(shù)數(shù)據(jù)
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.
Features
Low Differential Applications—Can accurately control at pressure differentials as low as 2.9 psid / 0,2 bar d
Bubble-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 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 troubleshooting
Full 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.
