Fisher? EZR 系列減壓調壓器

EZR 型指揮器作用式減壓調壓器運行準確、流暢、安靜，關斷嚴密，使用壽命長，即使在臟污工況中也能有很好的表現。 EZR 系列可安裝在各種應用中，如天然氣輸送/分輸系統、工業和商業設施。 EZROSX 型可用于關斷設備，通過完全地阻止氣體流向下流系統，提供過壓和/或欠壓保護。廣州奧麗斯特燃氣設備有限公司是美國FISHER產品華南區域（廣東?。┌瘓F授權代理商。2020美國FISHER技術選型020*叁貳貳0162張S費希爾調壓網 【張工同微XIN】

功 能

嚴密關斷—金屬塞設計可使顆粒和碎屑偏離閥膜，帶來的關斷效果，延長維護間隔。

防碎屑保護—EZR 系列閥籠創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。

運行安靜—標準閥籠可實現的減噪效果，使 EZR 產品較同類的柔性元件調壓器噪聲低 6-8 dBa。

使用壽命長—經現場驗證的閥膜具有分層纖維結構，凸起式焊邊和模制形狀，從而具有更高的強度、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佳的液體處理能力，且運行為安靜。 Fisher? 產品經實驗室檢測，其公布的產品流體數據皆能 實現。

行程指示器—簡化了維護過程的檢測和系統故障排查

—161EB 系列、161AY 系列和 PRX/120 先導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 型切斷在出現過壓或失壓時會中斷供氣。

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 available 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 dipahragm 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.

Travel 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 control.

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