詳細(xì)介紹
GDC-J型電磁高真空擋板閥是以電磁力為動(dòng)力直接帶動(dòng)閥板動(dòng)作，使閥門開啟或關(guān)閉。適用于真空系統(tǒng)中，用來(lái)切斷或?qū)饬?。適用介質(zhì)為純凈空氣和非腐蝕性氣體。
帶反饋信號(hào)。
■ GDC-J型－電磁高真空擋板閥
Electro High Vacuum Flapper Valve
■ GDC-JQelectro high vacuum butterfly valve uses electromagnetic force to directly drive valve disc working. thus to make valve opened ro closed. It is applicable for vacuum system to cut off or put through the airflow. When valve is closed. and there is atmospheric pressure above the sealing face and vacuum below the sealing face, here the sealing effect is the best. Applicable medium can be pure air and noncorrosive gases.
