費希爾Fisher 63EG 型指揮器作用式泄壓閥可用于液體和氣體應用。63EG 也適合節(jié)流背壓或旁路應用。 兩種結(jié)構(gòu)的主閥門都使用快速更換閥芯包以便于快速進行維護。 對于遠程監(jiān)控，63EG 型閥門可使用位置監(jiān)控器支架 (PMB) 將 4300 系列無線位置監(jiān)控器安裝到行程指示器。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?。┌瘓F授權(quán)代理商。2020美國FISHER技術(shù)選型020*叁貳貳0162張S中國費希爾調(diào)壓網(wǎng)【張工15876552411手機同微XIN】

功能

運行安靜—Whisper Trim? 籠選項可將高速氣體的噪聲降低 10 分貝。 帶有 Whisper Trim 的調(diào)壓器專為泄壓閥出口上經(jīng)常出現(xiàn)聲速氣體的高壓應用設計。

嚴密關(guān)斷—刀刃金屬塞和軟閥座提供氣密性關(guān)斷。

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。

低壓升—6358 系列泄壓閥指揮器能減小壓升，避免系統(tǒng)過壓。

流通能力—Fisher 產(chǎn)品經(jīng)實驗室檢測，其公布的產(chǎn)品流體數(shù)據(jù)皆能 實現(xiàn)。

行程指示器—簡化了維護過程的檢測和系統(tǒng)故障排查

穩(wěn)定啟動—指揮器的獨特中空閥桿可在主閥塞頂部快速取壓，避免正常系統(tǒng)啟動期間主閥打開

Fisher Type 63EG pilot-operated pressure relief valves may be used for both liquid and gas service.Type 63EG is also suitable for throttling backpressure or bypass applications. The main valves in both constructions use quick-change trim package for fast maintenance. For remote monitoring, a Position Monitor Bracket (PMB) is available for the Type 63EG to mount the 4300 Series Wireless Position Monitors to the travel indicator.

Features

Quiet Operation—The Whisper Trim? cage option can reduce noise from high-velocity gas by as much as 10 decibels. Whisper Trim equipped regulators are especially engineered for high-pressure applications where sonic gas velocities are often encountered at relief valve outlets.

Tight Shutoff—A knife-edged metal plug and soft seat provide bubble tight shutoff.

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

Low Buildup—6358 Series relief valve pilots reduce the buildup required to protect system from overpressure.

Full Usable Capacity—Fisher brand products are laboratory tested. of the published flow capacity can be used with confidence.

Travel Indicator—Simplifies in-service inspection and system troubleshooting

Stable Startup—The unique hollow valve stem in the pilot provides quick pressure registration on top of the main
