GDQ型气动高真空挡板阀概述 I. Overview of GDQ Pneumatic High Vacuum Baffle Valve

GDQ type pneumatic high vacuum baffle valve is vacuum The valve series uses electromagnetic reversing valves to change the direction of the gas path, and controls and executes the cylinder to drive the valve to open and close. Used to switch on or off the air flow in the vacuum line. The applicable medium is pure air and non-corrosive gas. With feedback signal device.

Second, the main technical performance

Scope of application
