1098-EGR 和 1098H-EGR 型減壓器功能特點:
低壓差應用—可在壓力差低至 1 psid / 70 mbar d 的情況下執行精確的控制
精確壓力控制—無論負載或入口壓力如何變化,都能夠提供穩定、精確的下游壓力控制。
運行安靜—Whisper Trim™ 閥籠選項*高可降噪 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、清潔及更換閥內件。
完全無大氣排放—利用先導式控制系統將所有氣體排放至下游系統,因此不會將任何有害廢氣排放至空氣中。
較高的流量比—超大尺寸的閥膜和線性閥籠可實現較高的可調流量,面對下游流量需求的大幅變化,可為系統內提供出色的壓力控制。
嚴密切斷—銳利的金屬塞和軟閥座提供氣密切斷,可用于終端系統等需要正壓關閉的應用。
行程指示器—簡化了維護過程的檢測和系統故障排查

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 |
