Column valve

Introduction
The Column valve is used for connection of columns to the system, and to direct the flow
onto the column. Up to five columns can be connected to the Column valve simultane-
ously. The valve also has a built-in by-pass function that enables by-passing of connected
columns.
Pressure monitors that measure the actual pressure over a column are integrated into
the inlet and outlet ports of the Column valve. For further information on the pressure
monitors, see Section 3.8 Pressure monitors, on page 78.
The number of column positions can be increased by installing an extra Column valve.
For information on how to install extra valves, please refer to Section 4.1 System extension
overview, on page 101.
