Fisher™ 1098-EGR和1098H-EGR 型减压器

1098-EGR和 1098H-EGR 型减压器功能特点：

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Zui高可降噪 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，不会将任何有害废气排放至空气中。

较高的流量比—超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，可为系统内提供出色的压力控制。

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 Types1098-EGR and 1098H-EGR regulators provide economical and accuratepressure control in a wide variety of applications; natural gasdistribution systems; fuel gas supply to industrial boilers,furnaces, ovens, and mixers; and large commercial / industrialestablishments such as shopping centers and schools. They are alsoused in plant air service and in liquid service.

Features

LowDifferential Applications—Can accuratelycontrol at pressure differentials as low as 1 psid / 70 mbard

Precise PressureControl—Provides stable and accurate downstream pressure controlregardless of load changes or inlet pressure variations.

Quiet Operation—TheWhisper Trim™ Cage option reduces noise by up to 30 dBa.

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

Absolutely NoAtmospheric Bleed—Eliminates nuisance and wasteful bleed gas toatmosphere by utilizing a pilot-operated control system, whichbleeds of the gas to the downstream system.

HighTurn Down Capability—The oversized diaphragm and linear cage allowfor high turn down, providing superior pressure control in systemswith large variations in downstream flow demand.

Tight Shutoff—Aknife-edged metal plug and soft seat provide bubble tight shutofffor use in applications where positive shutoff is required such asdead-end systems.

TravelIndicator—Simplifies in-service inspection and systemtroubleshooting
