Pneumatic high vacuum flapper valve
GDQ-J series pneumatic high-vacuum flapper valve uses compressed air as 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 switching on or off flow in a vacuum system. Pneumatic high vacuum baffle valve can be divided into GDQ-J type rubber seal and GDQ-J(b) type bellows seal according to the shaft seal structure. GDQ-J type is the angle through type,
