The valve part and the actuator part (solenoid) of these valves are sectioned by a diaphragm so the fluid does not come into contact with the metal parts of the solenoid. The wetted materials are PTFE, PEEK, or PPS, etc so as to be compatible with a wide range of fluids.

List of Diaphragm Isolated Valves

FV series
The size of this valve is just 4.2mm square. This is an innovative and groundbreaking ultra-small solenoid-driven diaphragm isolated valve. The internal volume is now only 1.1μl - contributes to reductions in reagent and improvements in accuracy.
