Used to extract fluids for manual analysis. Install this valve to the side
of the pipe in the case of horizontal installation. It is recommended that
a 1-inch ball valve be installed to the side of the pipe.
detector pipe for zero point adjustment. Install this valve at the top of
the pipe in the case of horizontal installation. It is recommended that a
1-inch ball valve be installed in the top of the pipe and zero point water
is supplied through this inlet using a vinyl hose etc.
If valve water pipe is connected to this valve, air cannot be extracted.
Therefore, another valve (vent valve) is needed to extract air.
Used to vent process fluids to open air when performing zero
adjustment. This helps the drinking water (density or consistency 0%)
enter the detector pipe easily. Install this valve in the top of the pipe in
the case of horizontal installation.
Used to drain the fluids before supplying drinking water (density or
consistency 0%) to the detector pipe for zero adjustment. Install this
valve at the lowest point of the pipe. It is recommended that a 1-inch
ball valve be installed at the lowest point of the pipe.
