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 valves select one of 4 to 16 dead-ended streams, directing it through the valve outlet to a sample valve, pressure sensor, detector, column, etc. The same configuration can also direct one stream to a number of outlets for fraction collection. Air actuators are useful in situations where any spark could be disastrous, where heat could coMostrar mais
