费希尔 1098-EGR 和 1098H-EGR 型调压器可在多种应用中实现经济而的压力控制，如天然气分输系统；工业锅炉、熔炉、烤炉和混合器的气体燃料供应；以及大型商业 / 工业机构（例如购物中心和学校）等应用场合。 它们也用于装置供气和液体应用。广州奥丽斯特燃气设备有限公司是美国FISHER产品华南区域（广东省）艾默生集团授权代理商。2020美国FISHER技术选型020*叁贰贰0162张S费希尔调压网www.zgfisher.com

低压差应用—可在压力差低至 1 psid / 70 mbar d 的情况下执行的控制

压力控制—无论负载或入口压力如何变化，都能够提供稳定、的下游压力控制。

运行安静—Whisper Trim™ 阀笼选项*可降噪 30 dBa。

简单直通式维护—顶部进入式设计使得维护更加简单。 无需从管线上卸下阀体即可检查、清洁及更换阀内件。

完全无大气排放—利用先导式控制系统将所有气体排放至下游系统，因此不会将任何有害废气排放至空气中。

较高的流量比—大尺寸的阀膜和线性阀笼可实现较高的可调流量，面对下游流量需求的大幅变化，可为系统内提供*的压力控制。

严密切断—锐利的金属塞和软阀座提供气密切断，可用于终端系统等需要正压关闭的应用。

行程指示器—简化了维护过程的检测和系统故障排查

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 nt 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 reced 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
