Introduction
This section provides instructions for removal and replacement of 3-port valves, and
applies to Buffer valve, Sample valve, Wash valve, and Outlet valve. Illustrations show
the Wash valve: the principles are the same for all four 3-port valves. Note that the ori-
entation of the valve ports on the instrument is different for the different valves.
NOTICE
The 3-port valves are similar in appearance. Make sure that the
correct part number is used when replacing valves, according to
the table below. Interchanging valves between positions can cause
