詳細介紹
BURKERT膜片閥187240由一個氣動的活塞驅(qū)動裝置、一個隔膜以及一個二通閥體構(gòu)成。帶有不銹鋼套的高品質(zhì)驅(qū)動裝置，確保了在衛(wèi)生或侵蝕性環(huán)境條件下的使用。利于流動的*閥體，能夠?qū)崿F(xiàn)較高的流量值和多樣化的使用可能性。驅(qū)動裝置設(shè)計允許將自動化單元簡單地集成到所有結(jié)構(gòu)分級中，從電氣/光學位置反饋裝置，經(jīng)過氣動的控制裝置，直至集成式總線接口和防爆的設(shè)備類型。高度集成的系統(tǒng)由閥門和自動化單元構(gòu)成，其特征在于設(shè)計的緊湊性和表面光滑性、集成式的控制空氣管道、防護級 IP65/67/NEMA4X 以及高化學抗性。
BURKERT膜片閥187240特點：
有利于流動且*的外殼
通過隔膜將介質(zhì)與驅(qū)動裝置嚴格分離
自動化單元及 ELEMENT 的簡單集成
帶有連接套頭、壓合接頭或焊接接頭的不銹鋼外殼
獲得 FDA 認證
