2.6.5 Check Valve (Part No. K9292DN or K9292DS)
This valve is mounted on the calibration gas line in the system such as the one using
flow setting units for manual calibration or the one performing when unburnt gas is
generated.
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.
