Column selection valve
The motorized column selection valve enables the system to switch solvent
flow to one of several columns. Such valves are only recognized by Alliance if
they are installed in the column heater.
The column selection valve is usually mounted in the column heater or column
heater/cooler (see the figure on page 43). It is installed on site as an add-on
option.
