The Series CV Compact Vacuum Valve has many configurations to suit your system’s particular needs. The angle and inline valves include pneumatic or manual actuation. The manual actuation is attained either through a rotary knob or toggle lever. The rotary knob option allows for conductance variability and includes a visual position indicator. The angle Cv Valve is available in two body sizes, ¾ inch and 1 inch. The inline model is available in the 1 inch size. Both models are available with a variety of flange options, including CF and ISO-KF flanges. The body is comprised of high grade, corrosion resistant, 304 stainless steel with non-magnetic properties to ensure more accurate gauge readings. MKS utilizes clean, tungsten inert gas (TIG) welding for significantly fewer entrapment areas. A formed 321 stainless steel bellows is incorporated into the Cv Valve. The stroke length has been optimized to ensure a longer life cycle while maintaining high conductance. Seal choices for the Cv Valve include Viton® and Chemraz® elastomers for leak-tight operation with a metal bonnet seal option in UHV applications. Vacuum exposed parts are clean and free of lubricants.
