費希爾 1098-EGR 和 1098H-EGR 型調(diào)壓器可在多種應用中實現(xiàn)經(jīng)濟而的壓力控制，如天然氣分輸系統(tǒng)；工業(yè)鍋爐、熔爐、烤爐和混合器的氣體燃料供應；以及大型商業(yè) / 工業(yè)機構(gòu)（例如購物中心和學校）等應用場合。 它們也用于裝置供氣和液體應用。廣州奧麗斯特燃氣設備有限公司是美國FISHER產(chǎn)品華南區(qū)域（廣東省）艾默生集團授權(quán)代理商。2020美國FISHER技術(shù)選型020*叁貳貳0162張S費希爾調(diào)壓網(wǎng)www.zgfisher.com

低壓差應用—可在壓力差低至 1 psid / 70 mbar d 的情況下執(zhí)行的控制

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。

運行安靜—Whisper Trim? 閥籠選項*可降噪 30 dBa。

簡單直通式維護—頂部進入式設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。

完全無大氣排放—利用先導式控制系統(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。

較高的流量比—大尺寸的閥膜和線性閥籠可實現(xiàn)較高的可調(diào)流量，面對下游流量需求的大幅變化，可為系統(tǒng)內(nèi)提供*的壓力控制。

嚴密切斷—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)閉的應用。

行程指示器—簡化了維護過程的檢測和系統(tǒng)故障排查

Fisher Types 1098-EGR and 1098H-EGR regulators provide economical and accurate pressure control in a wide variety of applications; natural gas distribution systems; fuel gas supply to industrial boilers, furnaces, ovens, and mixers; and large commercial / industrial establishments such as shopping centers and schools. They are also used in plant air service and in liquid service.

Features

Low Differential Applications—Can accurately control at pressure differentials as low as 1 psid / 70 mbar d

Precise Pressure Control—Provides stable and accurate downstream pressure control regardless of load changes or inlet pressure variations.

Quiet Operation—The Whisper Trim? Cage option reduces noise by up to 30 dBa.

Easy In-Line Maintenance—Top entry design enables easier maintenance. Trim parts can be inspected, cleaned and replaced without removing the body from pipeline.

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.

High Turn Down Capability—The oversized diaphragm and linear cage allow for high turn down, providing superior pressure control in systems with large variations in downstream flow demand.

Tight Shutoff—A knife-edged l plug and soft seat provide bubble tight shutoff for use in applications where positive shutoff is required such as dead-end systems.

Travel Indicator—Simplifies in-service inspection and system troubleshooting
