The standard version lets a single input be switched between two, up to six, output ports. An optional version with built-in check valves lets two, up to six, input ports be switched to a single output port. This eliminates multiple pressure gauges. Both versions come with detents for manual operation with a knob, or without them, for automatic operation with servos or stepper motors. The outside diameter of the valve head is about 1 in.
