GDQ-J大口径真空气动挡板阀安装及选型简介：

GDQ型气动高真空挡板阀是通过电磁换向阀改变气路方向，控制执行气缸驱动阀门作启闭运动。用于接通或切断真空管路中的气流。适用介质为纯净空气和非腐蚀性气体。带反馈信号装置。是通过电磁换向阀改变气路方向，控制执行气缸驱动阀板作上下运动，达到阀门的开启或关闭。阀门用于接通或切断真空管路中的气流。适用介质为纯净空气和非腐蚀性气体。带反馈信号装置,CCQ pneumatic ultra-high vacuum gate valve uses solenoid directional valve to change the direction of air passage, and controls the actuating cylinder to drive the valve disc up and down to make the valve opened or closed. It is used to put through or cut off the air passage in vacuum pipeline. Applicable medium can be pure air and noncorrosive gases.

With signal feedback device.
