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.

SD and SC valves select and isolate one of 4 to 16 streams, with the remainder dead-ended in the SD and flowing to a common outlet in the SC. The SF selector is similar, but carries the evolution a step further with the non-selected streams flowing through individual outlets.

The Modular Universal Actuator offers the same functionality as the Universal, in a flexible design that lets you mount the motor and electronics in different locations
