The DYC-JQ series electromagnetic vacuum pressure inflation valve is a special valve installed on the mechanical vacuum pump. It is installed in the intake port of the mechanical vacuum pump and opens and closes simultaneously at the pump. When the pump stops working or the power supply suddenly interrupts, the valve can rely on the pressure difference between the air and the vacuum to make the valve plate automatically close, the vacuum system is closed, to maintain its vacuum, and the air through the valve throttle hole filled into the pump cavity, thereby avoiding the pump oil countercurrent pollution of the vacuum system.

The DYC-JQ series of electromagnetic vacuum pressure charging valves are suitable for working air and non corrosive gases.
