BURKERT膜片閥2033系列用于控制高純度、無(wú)菌、侵蝕性或磨損性介質(zhì)。這種閥門具有很小的死角體積，能夠?qū)崿F(xiàn)*的容器灌注和排空過(guò)程。閥體由一個(gè)錠塊構(gòu)成，該錠塊無(wú)焊縫，由優(yōu)質(zhì)不銹鋼制造而成。底部排放閥的法蘭具有兩個(gè)斜角。這種結(jié)構(gòu)簡(jiǎn)化了其在容器中的定位和焊接過(guò)程。高品質(zhì)的隔膜將臨界性介質(zhì)與伺服驅(qū)動(dòng)裝置密封分離。通過(guò)氣動(dòng)先導(dǎo)式閥（單個(gè)先導(dǎo)式閥、閥島或控制頭），可以控制氣動(dòng)的伺服驅(qū)動(dòng)裝置?？刂乒δ?A，通過(guò)彈簧力在靜止位置關(guān)閉。
BURKERT膜片閥2033系列特點(diǎn)：
*的外殼，沒(méi)有焊縫
通過(guò)隔膜將介質(zhì)與驅(qū)動(dòng)裝置嚴(yán)格分離
堅(jiān)固的通用驅(qū)動(dòng)裝置，具有模塊化配件系列
帶有焊接接頭的不銹鋼外殼
質(zhì)量認(rèn)證 FDA / 3A
