美國阿斯卡隔離型微型閥,阿斯卡微型閥特點
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.
?PTFE diaphragm shields the internal components of
the solenoid from the media to handle the most
aggressive fluids
