Vacuum Angle Valve-Manually Actuated

GD-JISO-K/B series high vacuum manual baffle angle valve is one of the important components in the vacuum system. It relies on turning the knob up or down to open or close the valve plate. It adopts ISOK standard flange interface, which is quick to install and can be used as an opening and closing mechanism in high vacuum pipelines. The valve plate of this valve has a limit device for up and down movement to ensure the life of the valve plate sealing ring and bellows. The valve is suitable for air or low-corrosive gas.
