DDC-JQ 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.

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.

GQC-1.5, GQC-5 series electromagnetic high vacuum inflatable valve is driven by electromagnetic force. When the power is turned on, the valve is closed to isolate the vacuum system from the atmosphere. When the power is cut off, the valve is in the open state, and the atmosphere The vacuum system is introduced from the outside. GQC-4A series electromagnetic high vacuum inflation valve has two functions of power-on and power-off. There is an air filter inside the valve, which can be used to inflate the vacuum system. The applicable medium of the valve is air and non-corrosive gas.

C-Q5 electromagnetic high vacuum belt charging valve is connected to the high and low vacuum system, the valve is powered on and the valve is opened, and the charging port is closed at the same time, and the P and A end pipelines are connected; when the power is off, the valve plate is closed, and the P and A ends are cut off. Pipeline to ensure the vacuum of the system, and at the same time open the inflation port, and inflate the A end through the F end. GDC-5 electromagnetic high vacuum flapper valve is connected to the high and low vacuum pipelines to connect or cut off the air flow of the vacuum system. GDC-Q5 and GDC-5 vacuum valves are suitable for clean air and non-corrosive gases.
