I believe you are talking about a valve body that has been added to the tractor to run the loader. If it is plugged into the tractors factory outlet, and the lever is tied back to allow you to use a 2 lever spool valve for loader, then yes there should or can be oil flowing through the valve when in neutral. Someone has added an open centre spool valve to a closed system. That can cause the oil to warm up faster and could potentially cause some problems if used for extended heavy work. I would not worry about it as long as it works. If you put the tractor out in the field at full load for 10 hrs I would probably want to disconnect the loader spool, or untie the lever if that's how it operates. It is better to use open spool ad on if not sure if tractor is open or closed. If open centre and you use closed spool you cause the relief valve to run all the time and the oil will boil
