For what it's worth, here's the Stein-Dinse diagram for the 600 (with no oil cooler).
It looks from this as though the tap is just on/off rather than a bypass. Oil flowing out of the engine along hose 4 to the tap 8, then to the first float bowl via hose 10, to the second bowl via link-hose 9, and then finally back to the engine via hose 3.
The later model, without the heater, just appears to have the two oil ports blanked off with bolts 42.
So when the tap is closed on the earlier model, it's effectively replicating the blanking bolts on the later model.
Or not?
