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, or 4 position manifold configuration 

for use in chromatography, solvent selection, and process sampling.

Valve

Alternative Constructions Many alternative constructions are available and include a variety of voltages, 

electrical connectors, and materials of construction. 

ASCO Scientific can also custom design a valve for your specific application.
