BURKERT膜片閥2033系列用于控制高純度、無菌、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程。閥體由一個錠塊構(gòu)成，該錠塊無焊縫，由優(yōu)質(zhì)不銹鋼制造而成。底部排放閥的法蘭具有兩個斜角。這種結(jié)構(gòu)簡化了其在容器中的定位和焊接過程。高品質(zhì)的隔膜將臨界性介質(zhì)與伺服驅(qū)動裝置密封分離。通過氣動先導(dǎo)式閥（單個先導(dǎo)式閥、閥島或控制頭），可以控制氣動的伺服驅(qū)動裝置。控制功能 A，通過彈簧力在靜止位置關(guān)閉。
BURKERT膜片閥2033系列特點：
*的外殼，沒有焊縫
通過隔膜將介質(zhì)與驅(qū)動裝置嚴(yán)格分離
堅固的通用驅(qū)動裝置，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
