功能
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。
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)。
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。
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。
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)的關(guān)斷效果，延長(zhǎng)維護(hù)間隔。
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

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.
