Furthermore when I finished cleaning the 3 of them I had, and reassembling them, all 3 operated and transferred back and forth with the outputs open to air.
As far as testing them without air first, electrically, you should hear the electric solenoid transfer. (a small click)

There is no need to "kink" the output hoses for the valve to switch, but there is a need for a minimum amount of pressure to be available on the input side for the valve to fully switch as many of the valves used in FRC are air piloted. So if you hook it directly to a compressor and try to make it switch the loss of air out of the side that is currently activated may be large enough so that pressure doesn't build high enough for the valve to switch.
