BURKERT膜片閥180346特點(diǎn)：
有利于流動(dòng)且*的外殼
通過隔膜將介質(zhì)與驅(qū)動(dòng)裝置嚴(yán)格分離
自動(dòng)化單元及 ELEMENT 的簡(jiǎn)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(rèn)證
BURKERT膜片閥180346由一個(gè)氣動(dòng)的活塞驅(qū)動(dòng)裝置、一個(gè)隔膜以及一個(gè)二通閥體構(gòu)成。帶有不銹鋼套的高品質(zhì)驅(qū)動(dòng)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(dòng)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(dòng)裝置設(shè)計(jì)允許將自動(dòng)化單元簡(jiǎn)單地集成到所有結(jié)構(gòu)分級(jí)中，從電氣/光學(xué)位置反饋裝置，經(jīng)過氣動(dòng)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(dòng)化單元構(gòu)成，其特征在于設(shè)計(jì)的緊湊性和表面光滑性、集成式的控制空氣管道、防護(hù)級(jí) IP65/67/NEMA4X 以及高化學(xué)抗性。
