Electro-vacuum Charging Valve

DDC-JQ electro-vacuum charging valve is a safety valve for vacuum⊙ ⊙︿ , pump. It is mounted at the intake nozzle of vacuum pump⊙ ⊙︿ , synchronously opened and closed with the vacuum pump. In case that vacuum pump stops working or power supply is suddenly broken off⊙ ⊙︿ , valve will be cosed automatically to keep the vacuum system vacuum and the air charged into the cavity of vacuum pump⊙ ⊙︿ , thus to prevent pump oil from reverse flow that can pollute the vacuum system. Applicable medium can be pure air and noncorrosive gases.
