The DDC-JQ-B series electromagnetic vacuum belt inflating valve is a special valve installed on the mechanical vacuum pump. The valve and the pump are connected to the same power supply, and the opening and stopping of the pump directly controls the opening and closing of the valve. When the pump stops working or the power supply suddenly interrupts, the valve can automatically close the vacuum system, and the air through the pump inlet into the pump cavity, to avoid oil reflux pollution of the vacuum system.

The DDC-JQ-B series electromagnetic vacuum belt inflatable valves are suitable for working air and non corrosive gases.
