GDC-J series electromagnetic high vacuum flapper valve is a valve which is opened or closed by electromagnetic force and spring reset force. It is suitable for opening or separating airflow in vacuum system. When the valve is closed, the upper side of the sealing surface of the valve plate is allowed to bear atmospheric pressure, and the lower side is vacuum. Under this condition, the valve plate can be opened normally after the power box is connected to the power supply.
The suitable working medium is air, non corrosive and dust free gas.

GDQ series pneumatic high vacuum flapper valve


GDQ series pneumatic high vacuum flapper valve (also called the angle valve) is the use of compressed air as a driving force, through the electromagnetic valve to change the direction of air passage, push the cylinder piston moves up and down, to drive the valve stem up and down movement, the valve plate is opened or closed, which can turn on or cut off the gas flow in the vacuum system to. GDQ-J type is angle pass type, GDQ-S type is three pass type with pre pumping. The suitable working medium is air and non corrosive gas.
