Valve Applications – Diaphragm Valves

These illustrations show basic sample injection techniques using VICI diaphragm valves. The unique advantage of 10 port valves is that they reduce extra column volume by combining sampling and switching functions in a single valve. This minimizes expense, maintenance, service, and risk of leaks as compared to multiple 6 port valve systems.
