Vacuum Angle Valve-Pneumatically Actuated

GDQ series electric pneumatic high vacuum flapper angle valve is one of the important components in the vacuum system. It uses electrical signals as valve switch signals and relies on compressed air as the starting force for the valve plate to lift. When the power supply or compressed air is lost, the valve will automatically close by spring force. As the opening and closing mechanism in the high vacuum pipeline, this valve has the advantages of stable operation, reliable sealing, and long service life. It is one of the preferred valves for vacuum equipment automation. The valve is suitable for air or low-corrosive gas.
