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).
