Not really. Either the air flows directly *through* a valve
or - when the valve is pressed - it enters the valve, goes
through the extra loop back to the valve and leaves the
valve on the other side. In any case *all* valves are *always*
passed.

The only wrong thing with your model is the (visible) connection
between valves 1 and 2. This should be a very short U-loop starting
and ending on valve 2. Like the loops on valve 1 and 3, just shorter.

Otherwise a very nice model, BTW! (The brass could have a touch
less roughness.)
