11.  L9852CB/G7016XH Stop Valve
The stop valve and the nipple are mounted on the calibration gas line.
The nipple is used to connect the stop valve. They are attached when the option code (/SV) is selected for the ZR22S or the ZR202S.
Connection: Rc1/4 (L9852CB) or 1/4 NPT (F) (G7016XH)
Material: SUS316 (JIS) Weight: Approx. 80 g

12.  K9292DN/K9292DS Check Valve
This is used to prevent entry of sample gas into calibration gas line. Purpose is the same as stop valve, but is convenient, as it does not need to be opened or closed for calibration.
Mount directly on calibration gas inlet of detector in place of stop valve. However as source pressure of 150 kPa G or more is needed, standard gas unit cannot be used. When option code “/CV” of the ZR22S or the ZR202S is specified, check valve is provided.
Connection: Rc1/4 (K9292DN) or 1/4 NPT (F) (K9292DS)
Weight: Approx. 40g
