DDC-JQ series electromagnetic vacuum with inflation valveDetailed product description：

The DDC-JQ series electromagnetic vacuum belt inflation valve is a specialized valve installed on rotary vane vacuum pumps. The valve and pump are connected to the same power source, and the opening and stopping of the pump directly control the opening and closing of the valve. When the pump stops working or the power is suddenly interrupted, the valve can automatically seal the vacuum system and fill the pump chamber with atmosphere through the pump's inlet, avoiding pump oil backflow and pollution of the vacuum system.
