功 能

嚴(yán)密關(guān)斷—金屬塞設(shè)計(jì)可使顆粒和碎屑偏離閥膜，帶來(lái)卓越的關(guān)斷效果，延長(zhǎng)維護(hù)間隔。

防碎屑保護(hù)—EZR 系列閥籠創(chuàng)新性的流體通路可以減少碎屑帶來(lái)的損傷，而不銹鋼入口粗濾器可以防止大塊的碎屑損傷閥膜。

運(yùn)行安靜—標(biāo)準(zhǔn)閥籠可實(shí)現(xiàn)的減噪效果，使 EZR 產(chǎn)品較同類(lèi)的柔性元件調(diào)壓器噪聲低 6-8 dBa。

使用壽命長(zhǎng)—經(jīng)現(xiàn)場(chǎng)驗(yàn)證的閥膜具有分層纖維結(jié)構(gòu)，凸起式焊邊和模制形狀，從而具有更高的強(qiáng)度、更好的耐用性和更長(zhǎng)的使用壽命。

更大的液體處理能力—EZR 系列的流體路徑可獲得的液體處理能力，且運(yùn)行極為安靜。 Fisher? 產(chǎn)品經(jīng)實(shí)驗(yàn)室檢測(cè)，其公布的產(chǎn)品流體數(shù)據(jù)皆能 實(shí)現(xiàn)。

行程指示器—簡(jiǎn)化了維護(hù)過(guò)程的檢測(cè)和系統(tǒng)故障排查

高精度—161EB 系列、161AY 系列和 PRX/120 先導(dǎo)型提供了多出口壓力范圍和窄比例段，賦予 EZR 系列緊密且的控制能力。

一體化切斷—EZR-OSX 型切斷在出現(xiàn)過(guò)壓或失壓時(shí)會(huì)中斷供氣。

TypeEZR pilot-operated, pressure reducing regulator designed to giveaccurate, smooth, quiet operation, tight shutoff, and long life,even in dirty service. EZR Series can be installed in variousapplications such as natural gas transmission/distribution systems,industrial and commercial facilities. The Type EZROSX is availablewith a slam-shut device which provides overpressure protectionand/or under pressure protection by completely shutting off theflow of gas to the downstream system.

Features

TightShutoff—The metal plug isdesigned to deflect particles and debris away from the diaphragm,providing superior shutoff and increasing the time betweenmaintenance intervals.

DebrisProtection—The revolutionary flow path of the EZR Series cageminimizes the damage from debris while the stainless steel inletstrainer prevents large particles from damaging thediaphragm.

Quiet Operation—Thestandard cage provides best-in-class noise reduction, making theEZR Series 6-8 dBa than comparable flexible elementregulators.

LongLife—The field proven dipahragm design incorporates layered fabric,a raised bead edge and molded shape to increase strength,durability, and service life

HighCapacity—The flow path of the EZR Series produces best-in-classcapacity combined with the operation. Fisher? products arelaboratory tested so of the published flow capacity can beused with confidence.

TravelIndicator—Simplifies in-service inspection and systemtroubleshooting

HighAccuracy—Multiple outlet pressure ranges and narrow proportionalbands offered by the 161EB Series, 161AY Series and Type PRX/120pilots provide the EZR Series with tight, accuratecontrol.

IntegratedSlamshut—Type EZR-OSX slam-shut interrupts gas service during anoverpressure or underpressure condition.
