BURKERT膜片閥0262系列這種外部控制的直通閥經(jīng)由氣動(dòng)操作。它由一個(gè)隔膜驅(qū)動(dòng)裝置和一個(gè)二通閥套構(gòu)成。隔膜驅(qū)動(dòng)裝置能夠使主軸連同閥錐朝彈簧的方向運(yùn)動(dòng)，進(jìn)而接通閥門(mén)。主軸設(shè)計(jì)有雙層密封件，但沒(méi)有壓蓋。驅(qū)動(dòng)裝置外殼由環(huán)氧樹(shù)脂構(gòu)成。
BURKERT膜片閥0262系列特點(diǎn)：
無(wú)流量時(shí)關(guān)閉或打開(kāi)
外殼材料：黃銅、不銹鋼
雙主軸密封件
緊湊型結(jié)構(gòu)
