Swagelok^® Calibration and Switching Modules

The Swagelok calibration and switching module (CSM) provides a discrete switch between multiple process samples and conditions and selects process streams for analysis. The CSM pre-conditions the sample by ensuring samples are inserted into the analyzer at the appropriate pressure, temperature, flow, and filtration levels. Integrated flow loop design ensures consistent delivery times to the analyzer across all streams and eliminates any deadlegs or chance for cross-stream contamination.

The CSM is built on the Swagelok modular platform component platform, utilizing Swagelok stream selector valves (SSV), which allows the user to select the required configuration. The standard model accepts up to 10 process and two calibration fluids (liquid or gas). The main function of the CSM is to condition and select process streams, or to select a calibration stream for analysis. The system selects a fluid for analysis in response to a pneumatic pressure signal from an external source, typically the analyzer. The signal opens one of the SSV double block-and-bleed valve modules corresponding to the stream containing the fluid to be analyzed.

The Swagelok CSM offers several additional advantages, including:

• A variety of sample conditioning configurations available to meet application requirements
• A manual calibration option that allows the operator to calibrate the analyzer at any time
• Color-coded stream identification—process stream inlets will always be blue, calibration streams orange, bypass green, and outlet white
• A vented air gap that prevents the hazardous possibility of pneumatic air mixing with system fluid under pressure
• A modular design that allows easy maintenance
• A bypass option that allows high flow—and subsequent reduced sample time delay—to the CSM
