Idex - Valves - Manual Valves

Manual Valves are ideal if your application involves low frequency of use, demands operator control, or involves injection of varying sample volumes. We offer a wide selection of easy to use manual valves that include switching, injection, and selection valves. Note: For Valves please allow an additional 8 days lead time.

Available models

Our reliable Two-Position Switching Valves are designed to alternate between two fluid paths without manually disconnecting plumbing. In Chromatography, these valves can be used for sample injection, column switching, back flushing, sample enrichment, and other applicable techniques. In diagnostic or sequencing applications these switching valves may alternate flow paths to enable necessary fluidic tasks within the instrument.

Note: For Valves please allow an additional 8 days lead time.
