Overview
Overview
The CV25-K2K2-NOVV-24D Compact Vacuum Valve with angle ports, ISO-KF NW25 flanges, Viton seals and 24 VDC solenoid actuation is manufactured from 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. Vacuum exposed parts are clean and free of lubricants.
