WebWhen activating a valve for gas sampling injection in On/Off position, the sample loop is either connected or removed from being in series with the carrier gas. The carrier gas pressure will change/drop for a very short period. This is normal observations. A quick GSV activation will result in almost not notable pressure drops. WebApr 16, 2024 · SF valves allow a gas flow to be selected while the other unselected channels continue to flow through the valve. This type of valve has the advantage of easily and quickly bringing a representative sample to the analyzer. However, since the gas flow is constantly circulating, the sample consumption towards the valve is significant.
