GDC-J型高真空电磁挡板阀Electro High Vacuum Flapper Valve GDC-J型高真空电磁挡板阀是以电磁力为动力直接带动阀板动作，使真空阀门开启或关闭。GDC-J型电磁高真空挡板阀适用于真空系统中，高真空电磁挡板阀用来切断或导通气流。高真空电磁挡板阀适用介质为纯净空气和非腐蚀性气体。带反馈信号。温州奥斯科阀门科技有限公司专业生产的真空阀门广泛适用各类气体，液体等正、负压力管道系统，符合GMP标准。
GDC-JQelectro high vacuumbutterfly valveuses 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. GDC-J型高真空电磁挡板阀、电磁真空挡板阀 主要技术性能Main Technical Performance
