DOLDR型電動超高真空插板閥產(chǎn)品概述：
DOLDR型電動超高真空插板閥是通過電動裝置驅(qū)動閥桿帶動閥板作上下運(yùn)動，達(dá)到閥門的開啟或關(guān)閉。閥門用于接通或切斷真空管路中的氣流。適用介質(zhì)為純凈空氣和非腐蝕性氣體，帶反饋信號裝置。
DOLDR electric ultra-high vacuum gate valve uses electric device to drive the stem, moving valve disc up and down to make the valve opened or closed. It is used to put through or cut off the airflow in vacuum pipeline. Applicable medium can be pure air and noncorrosive gases. With signal feedback device.
