費希爾Fisher EZR 型先導式泄壓閥或背壓調(diào)壓器通常在城市門站和區(qū)站中用作過壓保護泄壓閥，或在商業(yè)和工業(yè)應用中用作背壓調(diào)壓器。 其運行安靜、順暢，關(guān)斷嚴密且使用壽命長，即使在臟污的工況下也能有很好的表現(xiàn)。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—標準閥籠可實現(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。

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，且運行極為安靜。 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)。

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

防碎屑保護—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。

嚴密關(guān)斷—金屬塞設計可使顆粒和碎屑偏離閥膜，帶來的關(guān)斷效果，延長維護間隔。

Fisher Type EZR pilot-operated, pressure relief valve or backpressure regulator is typically used in city gate and district stations as a relief valve for overpressure protection, or in commercial and industrial applications as a backpressure regulator. It provides smooth, quiet operation, tight shutoff, and long life, even in dirty service.

Features

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

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.

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

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.

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.

Travel Indicator—Simplifies in-service inspection and system troubleshooting

Versatility—By changing from a relief piloting system to a pressure reducing piloting system, a Type EZR relief valve or backpressure regulator easily becomes a pressure reducing regulator.
