In-Line Check Values
The ASI in-line check valve incorporates many of the innovations
of our self-priming replacement check valves. It is a rapid closure
cartridge valve that features very low resistance to flow, low internal
volume, and operates independently of gravity. It is protected
from solvent contamination by a 1/4" diameter 2 micron frit, and features
crush-proof construction. The valve may be used whenever fluid
flow needs to be restricted to one direction. Applications include prevention
of post column derivitization fluids from back-flowing into the column
in the event of mobile phase pump failure. This valve is also available in a high temperature version that will
operate at up to 125º C and 5000 PSI. (Please call for more information).
