One actuator can be used on any selector, from 2 to 96 positions, so you can stock only one type of actuator even if you have a variety of multiposition valves. Valve position memory is maintained even in the event of a power failure.
The direction reversal feature means that if a 6 position stream selection valve is on stream 1 and you select stream 6, you have the option of stepping "backwards" to stream 6 instead of passing through 2, 3, 4, and 5.
RS-232 control offers various commands like position access, direction control, shortest route, etc. (The RS-232 cable must be ordered separately.)
Some valves are harder or easier than others to rotate, so we offer two microelectric models - high speed and high torque.
