2.7.3 Check Valve (Part No. K9292DN or K9292DS)
This valve is mounted on the calibration gas line (directly connected to the detector).
This is applied to a system based on the (System 2 and 3) system configuration .
This valve prevents the process gas from entering the calibration gas line. Although it
functions as a stop valve, operation is easier than a stop valve as it does not require
opening/closing at each calibration.
Screw a check valve, instead of a stop valve into the calibration gas inlet of the detector.
