    Introduction


    DDC-JQ electro-vacuum charging valve is a safety valve for vacuum pump. It is mounted at the intake nozzle of vacuum pump. In case that vacuum pump stops working or power supply is suddenly broken off, valve will be closed automatically to maintain the vacuum constant and inject air into the pump chamber, thus to prevent the pollution of vacuum system due to reverse flow of oil. Applicable medium can be pure air and noncorrosive gases.
