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 leaves the valve through port 4 to the system (autosampler etc.).
