The company's selector valve is designed for use as a quiet replacement for solenoid valves. A single input can be switched between 2, 3, 4, 5, or 6 output ports. It can be ordered with detents for manual operation with a knob or without detents for automatic operation with a servo or stepper motor. The non-selected ports are vented to atmosphere. The outside diameter of the valve head is a little over 1 inch, and the valve length depends on the choice of tube fittings. Beswick Engineeringhttp://rbi.ims.ca/4911-581
