Electromagnetic high vacuum flapper valve
GDCJ series electromagnetic high vacuum flapper valve is used to open or close the valve by electromagnetic force and spring return force. It is suitable for opening or blocking air flow in vacuum system. When the valve is closed, the upper side of the sealing surface of the valve plate is allowed to bear high pressure, and the lower side is vacuum. In this state, the valve plate can be opened normally after the power supply of the electrical control box is turned on. The applicable working medium is air, non-corrosive gas and gas without particle dust.
