or 4 position manifold configuration for use in chromatography, solvent selection, and process sampling.
? PTFE diaphragm shields the internal components of the solenoid from the media to handle the most aggressive fluids
? Compact size saves valuable space in equipment ? Low power consumption

Inert Isolation Type 2-Way “TFE” Isolation Valves 1/4 - 28 UNF Porting, In-line Mount
The Series 190 & 330 are 2-way, normally closed isolation valves constructed with TFE materials,
 which makes them virtually impervious to chemical attack.
The Series 190 is a single valve while the Series 330 offers the same valve in a 2, 3,
