BURKERT膜片閥2032系列用于調(diào)節(jié)高純度、無(wú)菌的、侵蝕性或磨損性介質(zhì)。借助于這種系統(tǒng)，可以進(jìn)行*的抽樣、以及排空或循環(huán)臨界性工藝介質(zhì)。閥體由一個(gè)*的材料塊機(jī)械加工而成（單塊結(jié)構(gòu) - 無(wú)焊縫）。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2032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
不銹鋼外殼
質(zhì)量認(rèn)證 FDA / 3A
