Positions of the Multi Purpose Valve
The Multi Purpose Valve allows easy software controlled switching between
different modes of operation.
Normal Operating Mode Without Mixer
In normal operating mode, the flow comes from the pump head, passes
the pressure sensor and arrives at the central port of the Multi Purpose
Valve. The flow passes the inline filter and leaves the valve through port 4
to the system (autosampler etc.).
