Dead-end flowpath –
SD configuration

Multiposition valves – high pressure – UW Type

SD valves select one of 4 to 16 dead-ended streams. The selected stream flows from the outlet to a sample valve, pressure sensor, detector, column, etc. The same flowpath can also be used to direct one stream to a number of outlets in applications such as fraction collection. See application suggestion.
