6 mpos Trapping Path Selector, manual, 1/16'' Fitting, 0.4 mm Port, 75°C / 5000psi, for Liquid, N60/E

Selectors (multiposition valves) step incrementally through continuous revolutions, instead of switching back and forth like two position valves. (Selectors step bi-directionally with electric and universal actuators.) The preload design allows the rotor to be inspected or replaced without taking the valve off the actuator. Valves ordered with a electric actuator are permanently aligned.Valco selectors are available in five lower pressure flowpaths typically used in gas chromatography applications (most also available with the built-in purge feature), and two high pressure flowpaths suitable for high performance liquid chromatography.

ST selectors are used for multi-column, multi-sample, or multi-trap operations, and are available for use with 4 to 16 loops, or positions. Valves can be ordered with matched loops already installed.

Manual actuation offers the advantages of simplicity and low cost.
