Vacuum Angle Valve-Manually Actuated

GD-JISO-KF/B series high vacuum manual baffle angle valve is one of the important components in the vacuum system. It opens or closes the valve plate by rotating the knob upward or downward. It adopts ISO-KF standard flange interface, which is quick to install and can be used as the opening and closing mechanism in the high vacuum pipeline. The valve plate of this valve has a limit device for moving up and down to ensure the life of the valve plate sealing ring and bellows. The valve is suitable for air or low-corrosive gas.
