Fisher? EZR 系列減壓調(diào)壓器

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，帶來的關(guān)斷效果，延長維護(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)品較同類的柔性元件調(diào)壓器噪聲低 6-8 dBa。

使用壽命長—經(jīng)現(xiàn)場驗(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，其公布的產(chǎn)品流體數(shù)據(jù)皆能 實(shí)現(xiàn)。

行程指示器—簡化了維護(hù)過程的檢測和系統(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)過壓或失壓時(shí)會中斷供氣。

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

Features

Tight Shutoff—The metal plug is designed to deflect particles and debris away from the diaphragm, providing superior shutoff and increasing the time between maintenance intervals.

Debris Protection—The revolutionary flow path of the EZR Series cage minimizes the damage from debris while the stainless steel inlet strainer prevents large particles from damaging the diaphragm.

Quiet Operation—The standard cage provides best-in-class noise reduction, making the EZR Series 6-8 dBa quieter than comparable flexible element regulators.

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

High Capacity—The flow path of the EZR Series produces best-in-class capacity combined with the quietest operation. Fisher? products are laboratory tested so of the published flow capacity can be used with confidence.

Trel Indicator—Simplifies in-service inspection and system troubleshooting

High Accuracy—Multiple outlet pressure ranges and narrow proportional bands offered by the 161EB Series, 161AY Series and Type PRX/120 pilots provide the EZR Series with tight, accurate cool.

Integrated Slamshut—Type EZR-OSX slam-shut interrupts gas service during an overpressure or underpressure condition.
