GDQ-KF series straight-through pneumatic high-vacuum flapper valve uses compressed air as the power, changes the direction of the air path through the electromagnetic reversing valve, pushes the cylinder piston to move up and down, drives the valve stem to move up and down, and makes the valve plate open or close, so as to achieve The purpose of turning on or off the air flow in the vacuum system. The applicable working medium is air and non-corrosive gas.
