DDC-JQ-B serise
electromagnetic vacuumwith inflation valve
DDC-JQ-B series electromagnetic vacuum filling valve is a special valve installed on the mechanical vacuum pump. The valve and the 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 supply is interrupted suddenly, the valve can automatically close the vacuum system and fill the air into the pump cavity through the pump inlet to avoid the backflow of pump oil from polluting the vacuum system. The applicable working medium is air and non-corrosive gas.
