DYC-JQ series electromagnetic vacuum differential pressure charging valve is a special valve installed on mechanical vacuum pump. It is installed in the air inlet of the mechanical vacuum pump and opens and closes synchronously with the pump. When the pump stops working or the power supply is suddenly interrupted, the valve can automatically close the valve plate depending on the pressure difference between the atmosphere and the vacuum, seal the vacuum system, maintain its vacuum degree, and fill the air into the pump cavity through the throttle hole of the valve to avoid the pump oil backflow polluting the vacuum system.

The applicable working medium is air and non corrosive gas.
