NORGREN三位電磁閥與數(shù)字閥：三位電磁閥的閥芯有三個工作位置，平時不通電，處于微啟狀態(tài)，閥門提供初始流量；給一種電信號，電磁閥全開，提供大流量；給另種電信號，閥門關(guān)閥。閥門還帶有手動裝置， 使得長期關(guān)閥時也不需耗電。三位電磁閥可視為一種結(jié)構(gòu)更為緊湊的雙聯(lián)電磁閥，它很方便地實(shí)現(xiàn)三位調(diào)節(jié)，得到了很多應(yīng)用。進(jìn)一步的思路是n個大小成一定比例的電磁閥組成2n種流量,類似于數(shù)字電路稱這種組合閥為數(shù)字閥。實(shí)際上兩個大小不同的雙聯(lián)閥或三位閥就可產(chǎn)生24=16或32=9種流量,已經(jīng)能達(dá)非常高的精度。從原理上說,它與工控計算機(jī)配套具有優(yōu)勢,但由于應(yīng)用領(lǐng)域還沒有提出大量的需求,這項技術(shù)尚處于試驗階段。8241300.9186.230.50

寶碩電磁閥：自保持型電磁閥就是只需瞬間通電即完成閥門開關(guān)動作,閥芯位置不需電來保持。它的優(yōu)點(diǎn)在于節(jié)約能源尤其是用電池作電源的場合，而且可不考慮溫升，從而線圈壽命長，在高低溫、防爆等場合有較高安全性。常見的有機(jī)械式保持和永磁體保持，又分雙線圈和單線圈，以單線圈磁保持結(jié)構(gòu)zui為簡單。它是以改變直流電源極性改變對應(yīng)閥門開關(guān)的兩種狀態(tài)。這種電磁閥單獨(dú)安裝線圈外部接線需加轉(zhuǎn)換開關(guān)，而與智能儀表配套則十分方便。IC卡預(yù)收費(fèi)煤氣表和水表所配的電磁閥是儀表成敗的關(guān)鍵之一，其中的自保持技術(shù)又是電磁閥的成敗的重要因素，國內(nèi)的自保持電磁已日趨成熟
