| The Cheminert design involves a flat rotor
which is engraved with slots to connect the ports and a stator
which is held against the rotor at a constant, preset force. When
repairs are required, just take out two or three screws,
replace the rotor, and put the screws back in and tighten them.
No adjustments are possible, much less required. Other advantages
of the design include easy panel mounting, low actuating torque,
and compact size. The Cheminert design offers configurations for
basic flow switching, sample injection, and stream selection up
to 10 positions (26 positions in some models).
