IDA™ In Situ Diagnostic Access Isolation Valves increase the accuracy of, and reduces the time needed for, gauge or capacitance manometer zeroing and calibration during preventative maintenance intervals. They also provide a process chamber access port that enables additional functions, such as system leak checks and diagnostics. Accurate, absolute pressure measurement in-situ with the IDA valve ensures uniformity and repeatability on a system and a system-to-system basis. Process system uptime and productivity are also enhanced, and costs are reduced.

Features
Diagnostics Access Valve Design
The IDA Valve joins a pneumatically actuated primary valve with a manually actuated secondary valve, both based on the MKS Cv Valve design. Functionally, it resembles a pair of two-way valves joined by a tee where V1 is the primary valve and V2 is the secondary valve. This configuration allows for two standard, mirror-image port orientations for your system: a left-oriented body and a rightoriented body.
Applications
The IDA™ Valve (In-situ Diagnostics Access Valve) is a multi-purpose, multi-port, dual valve designed to replace the standard isolation valve used in capacitance manometer and other types of gauge isolation in the semiconductor industry. It is an extension of the proven family of compact, high conductance modular MKS Cv™ Valves.
Gauge Diagnostics and Calibration Verification
In the figure, the gauge is isolated from the process chamber (Vl closed). Valve V2 is then opened, creating a short, high conductance access path for in-situ gauge zeroing or calibration. This can be done via a high quality leak detector/high vacuum system or a complete transportable calibration system.
Left or Right Orientations
On the x-y-z axis to the bottom left, a right-oriented valve body is shown as an example. Ports F1, F2, and F3 (process chamber, gauge, and reference/access ports, respectively) correspond to the axes as follows:
- A right-oriented valve body has its three vacuum ports, F1, F2, and F3, aligned with the +x, +y, and +z axes, respectively.
- A left-oriented valve body has its three vacuum ports, F1, F2, and F3, aligned with the +x, -y, and +z axes, respectively.
