Using an M-SWITCH™ valve
4.1
Fluidic principle
The M-SWITCH™ is an 11-port / 10-position valve. This means that eleven (11) ports can be connected with
tubings, and that it is possible to choose between ten (10) positions linking one of the ten (10) external ports to
the central port of the valve.
Here is the fluidic diagram of an M-SWITCH™. The
dark blue port at the centre of the M-SWITCH™ is
the
central port
. The light blue ports are the
external ports
. The central port can be connected
in turns to each external port, from port #1 to port
#10
depending
on
the
chosen
position
(respectively from Position 1 to Position 10).
The
Default position of the M-SWITCH™
when
the M-SWITCH™ is not powered is
the last
actuated position
.
The M-SWITCH™ is a
bidirectional valve
,
meaning that the fluid can flow inside the M-
SWITCH™ in both directions:
Distributor mode
: fluid flows from the
central port to one external port
(according to the selected position).
Selector mode
: fluid flows from one of
the external ports (according to the
selected position) to the central port.
The
non used ports must be closed with
plugs
(gray squares on the diagram) to
preserve the M-SWITCH™ good operation.
In the same way as the 2-SWITCH™, it is
possible to use a plugged position to close
a fluidic path.
