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)品較同類的柔性元件調(diào)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(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)過程的檢測(cè)和系統(tǒng)故障排查
