Specifications

GDC-J electromagnetic high vacuum damper valve is used to open or close the valve by electromagnetic and spring-return force, applying itself to open or cut off the air current within the vacuum system. It allows to bear the atmospheric pressure over the valve sealed surface while the downside is full of vacuum as the valve is closed. Under such circumstance can the valve be opened regularly after connecting the electrical control power.
