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壓器噪聲低6-8dBa。
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。
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。
行程指示器—簡化了維護過程的檢測和系統(tǒng)故障排查
功能多樣—通過將泄壓先導系統(tǒng)轉變?yōu)闇p壓先導系統(tǒng),EZR型泄壓閥或背壓調節(jié)器可以輕松地轉變?yōu)闇p壓調壓器。
