In gauge isolation applications, the Cv Valve’s high conductance ensures more accurate readings and helps improve gauge response time. The Cv Valve can isolate the sensor from the chamber during venting to atmosphere. If a capacitance manometer is being used, the isolation valve will prevent overpressuring the diaphragm. Where the gauge is used to monitor pressure, and not required for process control, it can be isolated during the process to prevent process gases from contaminating the gauge.

The Cv 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. 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.
