Function of the Versatile valve
The Versatile valve is a 4-port, 4-position valve, which can be used to add extra features
to the flow path. For example, the valve can be used to connect external equipment to
the flow path during parts of a run. The versatile valve is labeled V9-V or V9H-V.
It is possible to install up to four versatile valves simultaneously in ÄKTA avant. The
configuration is defined by the module's Node ID. The Node ID is set by positioning the
arrows of the two rotating switches at the back of the valve, see Section 9.15 Check and
change the Node ID of a module, on page 515.
The valve can be installed in any free module position. It is also possible to install the
valve in an Extension box. See Section 2.6.3 Extension box, on page 53.
