GQC-1.5 and GQC-5 electromagnetic high vacuum inflation valves are powered by electromagnetic force. When the power is turned on, the valve is closed, isolating the vacuum system from the atmosphere; When the power is cut off, the valve is in the open state, and the atmosphere is introduced into the vacuum system from the outside. The GQC-4A electromagnetic high vacuum inflation valve has two functions: power on opening and power on closing. The valve is equipped with an air filter and can be used to inflate the vacuum system.  
The medium suitable for valves is air and non corrosive gases.
